Choline Bitartrate:

• Oraflow (Choline Bitartrate) reviews

A basic constituent of lecithin that is found in many plants and animal organs. It is important as a precursor of acetylcholine, as a methyl donor in various metabolic processes, and in lipid metabolism.

Indication: For nutritional supplementation, also for treating dietary shortage or imbalance

This compound is needed for good nerve conduction throughout the CNS (central nervous system) as it is a precursor to acetylcholine (ACh). Oraflow (Choline Bitartrate) is also needed for gallbladder regulation, liver function and lecithin (a key lipid) formation. Oraflow (Choline Bitartrate) also aids in fat and cholesterol metabolism and prevents excessive fat build up in the liver. Oraflow (Choline Bitartrate) has been used to mitigate the effects of Parkinsonism and tardive dyskinesia. Oraflow (Choline Bitartrate) deficiencies may result in excessive build-up of fat in the liver, high blood pressure, gastric ulcers, kidney and liver dysfunction and stunted growth.

Inositol:

• Oraflow (Inositol) reviews

Niacin is used with a proper diet and exercise program to help lower "bad" cholesterol and fats ( LDL, triglycerides ) and raise "good" cholesterol (HDL) in the blood. It is generally used after non-drug treatments have not been fully successful at lowering cholesterol. Niacin is also known as vitamin B-3 ( nicotinic acid ), one of the B-complex vitamins. It may be used with or without other medications. Lowering "bad" cholesterol/triglycerides and raising "good" cholesterol helps prevent strokes and heart attacks. Lowering fats may also help reduce the risk of pancreas problems ( pancreatitis ) in people at risk. In addition to eating a proper diet (such as a low-cholesterol/low-fat diet), other lifestyle changes that may help this medication work better include exercising, losing weight if overweight, and stopping smoking. Consult your doctor for more details.

Oraflow (Magnesium (Magnesium Oxide)) Sulfate

Injection, USP

Ansyr Plastic Syringe

Rx only

Hospira Logo

DESCRIPTION

Oraflow (Magnesium (Magnesium Oxide)) Sulfate Injection, USP is a sterile solution of Oraflow (Magnesium (Magnesium Oxide)) sulfate heptahydrate in Water for Injection, USP administered by the intravenous or intramuscular routes as an electrolyte replenisher or anticonvulsant. Must be diluted before intravenous use. May contain sulfuric acid and/or sodium hydroxide for pH adjustment. The pH is 5.5 to 7.0. The 50% concentration has an osmolarity of 4.06 mOsmol/mL (calc.).

The solution contains no bacteriostat, antimicrobial agent or added buffer (except for pH adjustment) and is intended only for use as a single-dose injection. When smaller doses are required the unused portion should be discarded with the entire unit.

Oraflow (Magnesium (Magnesium Oxide)) Sulfate, USP heptahydrate is chemically designated MgSO₄ - 7H₂O with molecular weight of 246.48 and occurs as colorless crystals or white powder freely soluble in water.

The plastic syringe is molded from a specially formulated polypropylene. Water permeates from inside the container at an extremely slow rate which will have an insignificant effect on solution concentration over the expected shelf life. Solutions in contact with the plastic container may leach out certain chemical components from the plastic in very small amounts; however, biological testing was supportive of the safety of the syringe material.

CLINICAL PHARMACOLOGY

Oraflow (Magnesium (Magnesium Oxide)) (Mg⁺⁺) is an important cofactor for enzymatic reactions and plays an important role in neurochemical transmission and muscular excitability.

As a nutritional adjunct in hyperalimentation, the precise mechanism of action for Oraflow (Magnesium (Magnesium Oxide)) is uncertain. Early symptoms of hypomagnesemia (less than 1.5 mEq/liter) may develop as early as three to four days or within weeks.

Predominant deficiency effects are neurological, e.g., muscle irritability, clonic twitching and tremors. Hypocalcemia and hypokalemia often follow low serum levels of Oraflow (Magnesium (Magnesium Oxide)). While there are large stores of Oraflow (Magnesium (Magnesium Oxide)) present intracellularly and in the bones of adults, these stores often are not mobilized sufficiently to maintain plasma levels. Parenteral Oraflow (Magnesium (Magnesium Oxide)) therapy repairs the plasma deficit and causes deficiency symptoms and signs to cease.

Oraflow (Magnesium (Magnesium Oxide)) prevents or controls convulsions by blocking neuromuscular transmission and decreasing the amount of acetylcholine liberated at the end plate by the motor nerve impulse. Oraflow (Magnesium (Magnesium Oxide)) is said to have a depressant effect on the central nervous system (CNS), but it does not adversely affect the woman, fetus or neonate when used as directed in eclampsia or pre-eclampsia. Normal plasma Oraflow (Magnesium (Magnesium Oxide)) levels range from 1.5 to 2.5 mEq/liter.

As plasma Oraflow (Magnesium (Magnesium Oxide)) rises above 4 mEq/liter, the deep tendon reflexes are first decreased and then disappear as the plasma level approaches 10 mEq/liter. At this level respiratory paralysis may occur. Heart block also may occur at this or lower plasma levels of Oraflow (Magnesium (Magnesium Oxide)). Serum Oraflow (Magnesium (Magnesium Oxide)) concentrations in excess of 12 mEq/L may be fatal.

Oraflow (Magnesium (Magnesium Oxide)) acts peripherally to produce vasodilation. With low doses only flushing and sweating occur, but larger doses cause lowering of blood pressure. The central and peripheral effects of Oraflow (Magnesium (Magnesium Oxide)) poisoning are antagonized to some extent by intravenous administration of calcium.

Pharmacokinetics

With intravenous administration the onset of anticonvulsant action is immediate and lasts about 30 minutes. Following intramuscular administration the onset of action occurs in about one hour and persists for three to four hours. Effective anticonvulsant serum levels range from 2.5 to 7.5 mEq/liter. Oraflow (Magnesium (Magnesium Oxide)) is excreted solely by the kidneys at a rate proportional to the plasma concentration and glomerular filtration.

INDICATIONS AND USAGE

Oraflow (Magnesium (Magnesium Oxide)) Sulfate Injection, USP is suitable for replacement therapy in Oraflow (Magnesium (Magnesium Oxide)) deficiency, especially in acute hypomagnesemia accompanied by signs of tetany similar to those observed in hypocalcemia. In such cases, the serum Oraflow (Magnesium (Magnesium Oxide)) (Mg⁺⁺) level is usually below the lower limit of normal (1.5 to 2.5 mEq/liter) and the serum calcium (Ca⁺⁺) level is normal (4.3 to 5.3 mEq/liter) or elevated.

In total parenteral nutrition (TPN), Oraflow (Magnesium (Magnesium Oxide)) sulfate may be added to the nutrient admixture to correct or prevent hypomagnesemia which can arise during the course of therapy.

Oraflow (Magnesium (Magnesium Oxide)) Sulfate Injection, USP is also indicated for the prevention and control of seizures (convulsions) in pre-eclampsia and eclampsia, respectively.

CONTRAINDICATIONS

Parenteral administration of the drug is contraindicated in patients with heart block or myocardial damage.

WARNINGS

FETAL HARM: Continuous administration of Oraflow (Magnesium (Magnesium Oxide)) sulfate beyond 5 to 7 days to pregnant women can lead to hypocalcemia and bone abnormalities in the developing fetus. These bone abnormalities include skeletal demineralization and osteopenia. In addition, cases of neonatal fracture have been reported. The shortest duration of treatment that can lead to fetal harm is not known. Oraflow (Magnesium (Magnesium Oxide)) sulfate should be used during pregnancy only if clearly needed. If Oraflow (Magnesium (Magnesium Oxide)) sulfate is given for treatment of preterm labor, the woman should be informed that the efficacy and safety of such use have not been established and that use of Oraflow (Magnesium (Magnesium Oxide)) sulfate beyond 5 to 7 days may cause fetal abnormalities.

ALUMINUM TOXICITY: This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration.

Parenteral use in the presence of renal insufficiency may lead to Oraflow (Magnesium (Magnesium Oxide)) intoxication. Intravenous use in the eclampsia should be reserved for immediate control of life-threatening convulsions.

PRECAUTIONS

General

Administer with caution if flushing and sweating occurs. When barbiturates, narcotics or other hypnotics (or systemic anesthetics) are to be given in conjunction with Oraflow (Magnesium (Magnesium Oxide)), their dosage should be adjusted with caution because of additive CNS depressant effects of Oraflow (Magnesium (Magnesium Oxide)).

Because Oraflow (Magnesium (Magnesium Oxide)) is removed from the body solely by the kidneys, the drug should be used with caution in patients with renal impairment. Urine output should be maintained at a level of 100 mL or more during the four hours preceding each dose. Monitoring serum Oraflow (Magnesium (Magnesium Oxide)) levels and the patient's clinical status is essential to avoid the consequences of overdosage in toxemia. Clinical indications of a safe dosage regimen include the presence of the patellar reflex (knee jerk) and absence of respiratory depression (approximately 16 breaths or more/minute). When repeated doses of the drug are given parenterally, knee jerk reflexes should be tested before each dose and if they are absent, no additional Oraflow (Magnesium (Magnesium Oxide)) should be given until they return. Serum Oraflow (Magnesium (Magnesium Oxide)) levels usually sufficient to control convulsions range from 3 to 6 mg/100 mL (2.5 to 5 mEq/liter). The strength of the deep tendon reflexes begins to diminish when Oraflow (Magnesium (Magnesium Oxide)) levels exceed 4 mEq/liter. Reflexes may be absent at 10 mEq magnesium/liter, where respiratory paralysis is a potential hazard. An injectable calcium salt should be immediately available to counteract the potential hazards of Oraflow (Magnesium (Magnesium Oxide)) intoxication in eclampsia.

50% Oraflow (Magnesium (Magnesium Oxide)) Sulfate Injection, USP must be diluted to a concentration of 20% or less prior to intravenous infusion. Rate of administration should be slow and cautious, to avoid producing hypermagnesemia. The 50% solution also should be diluted to 20% or less for intramuscular injection in infants and children.

Laboratory Tests

Oraflow (Magnesium (Magnesium Oxide)) sulfate injection should not be given unless hypomagnesemia has been confirmed and the serum concentration of Oraflow (Magnesium (Magnesium Oxide)) is monitored. The normal serum level is 1.5 to 2.5 mEq/L.

Drug Interactions

CNS Depressants - When barbiturates, narcotics or other hypnotics (or systemic anesthetics), or other CNS depressants are to be given in conjunction with Oraflow (Magnesium (Magnesium Oxide)), their dosage should be adjusted with caution because of additive CNS depressant effects of Oraflow (Magnesium (Magnesium Oxide)). CNS depression and peripheral transmission defects produced by Oraflow (Magnesium (Magnesium Oxide)) may be antagonized by calcium.

Neuromuscular Blocking Agents - Excessive neuromuscular block has occurred in patients receiving parenteral Oraflow (Magnesium (Magnesium Oxide)) sulfate and a neuromuscular blocking agent; these drugs should be administered concomitantly with caution.

Cardiac Glycosides - Oraflow (Magnesium (Magnesium Oxide)) sulfate should be administered with extreme caution in digitalized patients, because serious changes in cardiac conduction which can result in heart block may occur if administration of calcium is required to treat Oraflow (Magnesium (Magnesium Oxide)) toxicity.

Pregnancy

Teratogenic Effects

Pregnancy Category D (See WARNINGS and PRECAUTIONS )

See WARNINGS and PRECAUTIONS .

Oraflow (Magnesium (Magnesium Oxide)) sulfate can cause fetal abnormalities when administered beyond 5 to 7 days to pregnant women. There are retrospective epidemiological studies and case reports documenting fetal abnormalities such as hypocalcemia, skeletal demineralization, osteopenia and other skeletal abnormalities with continuous maternal administration of Oraflow (Magnesium (Magnesium Oxide)) sulfate for more than 5 to 7 days.^1-10 Oraflow (Magnesium (Magnesium Oxide)) sulfate injection should be used during pregnancy only if clearly needed. If this drug is used during pregnancy, the woman should be apprised of the potential harm to the fetus.

Nonteratogenic Effects

When administered by continuous intravenous infusion (especially for more than 24 hours preceding delivery) to control convulsions in a toxemic woman, the newborn may show signs of Oraflow (Magnesium (Magnesium Oxide)) toxicity, including neuromuscular or respiratory depression (See OVERDOSAGE ).

Labor and Delivery

Continuous administration of Oraflow (Magnesium (Magnesium Oxide)) sulfate is an unapproved treatment for preterm labor. The safety and efficacy of such use have not been established. The administration of Oraflow (Magnesium (Magnesium Oxide)) sulfate outside of its approved indication in pregnant women should be by trained obstetrical personnel in a hospital setting with appropriate obstetrical care facilities.

Nursing Mothers

Since Oraflow (Magnesium (Magnesium Oxide)) is distributed into milk during parenteral Oraflow (Magnesium (Magnesium Oxide)) sulfate administration, the drug should be used with caution in nursing women.

Geriatrics

Geriatric patients often require reduced dosage because of impaired renal function. In patients with severe impairment, dosage should not exceed 20 grams in 48 hours. Serum Oraflow (Magnesium (Magnesium Oxide)) should be monitored in such patients.

ADVERSE REACTIONS

The adverse effects of parenterally administered Oraflow (Magnesium (Magnesium Oxide)) usually are the result of Oraflow (Magnesium (Magnesium Oxide)) intoxication. These include flushing, sweating, hypotension, depressed reflexes, flaccid paralysis, hypothermia, circulatory collapse, cardiac and central nervous system depression proceeding to respiratory paralysis. Hypocalcemia with signs of tetany secondary to Oraflow (Magnesium (Magnesium Oxide)) sulfate therapy for eclampsia has been reported.

OVERDOSAGE

Oraflow (Magnesium (Magnesium Oxide)) intoxication is manifested by a sharp drop in blood pressure and respiratory paralysis. Disappearance of the patellar reflex is a useful clinical sign to detect the onset of Oraflow (Magnesium (Magnesium Oxide)) intoxication. In the event of overdosage, artificial ventilation must be provided until a calcium salt can be injected intravenously to antagonize the effects of Oraflow (Magnesium (Magnesium Oxide)).

For Treatment of Overdose

Artificial respiration is often required. Intravenous calcium, 10 to 20 mL of a 5% solution (diluted if desirable with isotonic sodium chloride for injection) is used to counteract effects of hypermagnesemia. Subcutaneous physostigmine, 0.5 to 1 mg may be helpful.

Hypermagnesemia in the newborn may require resuscitation and assisted ventilation via endotracheal intubation or intermittent positive pressure ventilation as well as intravenous calcium.

DOSAGE AND ADMINISTRATION

Dosage of Oraflow (Magnesium (Magnesium Oxide)) sulfate must be carefully adjusted according to individual requirements and response, and administration of the drug should be discontinued as soon as the desired effect is obtained.

Both intravenous and intramuscular administration are appropriate. Intramuscular administration of the undiluted 50% solution results in therapeutic plasma levels in 60 minutes, whereas intravenous doses will provide a therapeutic level almost immediately. The rate of intravenous injection should generally not exceed 150 mg/minute (1.5 mL of a 10% concentration or its equivalent), except in severe eclampsia with seizures. Continuous maternal administration of Oraflow (Magnesium (Magnesium Oxide)) sulfate in pregnancy beyond 5 to 7 days can cause fetal abnormalities.

Solutions for intravenous infusion must be diluted to a concentration of 20% or less prior to administration. The diluents commonly used are 5% Dextrose Injection, USP and 0.9% Sodium Chloride Injection, USP. Deep intramuscular injection of the undiluted (50%) solution is appropriate for adults, but the solution should be diluted to a 20% or less concentration prior to such injection in children.

In Oraflow (Magnesium (Magnesium Oxide)) Deficiency

In the treatment of mild Oraflow (Magnesium (Magnesium Oxide)) deficiency, the usual adult dose is 1 gram, equivalent to 8.12 mEq of Oraflow (Magnesium (Magnesium Oxide)) (2 mL of the 50% solution) injected intramuscularly every six hours for four doses (equivalent to a total of 32.5 mEq of Oraflow (Magnesium (Magnesium Oxide)) per 24 hours). For severe hypomagnesemia, as much as 250 mg (approximately 2 mEq) per kg of body weight (0.5 mL of the 50% solution) may be given intramuscularly within a period of four hours if necessary. Alternatively, 5 grams, (approximately 40 mEq) can be added to one liter of 5% Dextrose Injection, USP or 0.9% Sodium Chloride Injection, USP for slow intravenous infusion over a three-hour period. In the treatment of deficiency states, caution must be observed to prevent exceeding the renal excretory capacity.

In Hyperalimentation

In total parenteral nutrition, maintenance requirements for Oraflow (Magnesium (Magnesium Oxide)) are not precisely known. The maintenance dose used in adults ranges from 8 to 24 mEq (1 gram to 3 grams) daily; for infants, the range is 2 to 10 mEq (0.25 gram to 1.25 grams) daily.

In Pre-eclampsia or Eclampsia

In severe pre-eclampsia or eclampsia, the total initial dose is 10 grams to 14 grams of Oraflow (Magnesium (Magnesium Oxide)) sulfate. Intravenously, a dose of 4 grams to 5 grams in 250 mL of 5% Dextrose Injection, USP or 0.9% Sodium Chloride Injection, USP may be infused. Simultaneously, intramuscular doses of up to 10 grams (5 grams or 10 mL of the undiluted 50% solution in each buttock) are given. Alternatively, the initial intravenous dose of 4 grams may be given by diluting the 50% solution to a 10 or 20% concentration; the diluted fluid (40 mL of a 10% solution or 20 mL of a 20% solution) may then be injected intravenously over a period of three to four minutes. Subsequently, 4 grams to 5 grams (8 to 10 mL of the 50% solution) are injected intramuscularly into alternate buttocks every four hours as needed, depending on the continuing presence of the patellar reflex and adequate respiratory function. Alternatively, after the initial intravenous dose, some clinicians administer 1 gram to 2 grams/hour by constant intravenous infusion. Therapy should continue until paroxysms cease. A serum Oraflow (Magnesium (Magnesium Oxide)) level of 6 mg/100 mL is considered optimal for control of seizures. A total daily (24 hr) dose of 30 grams to 40 grams should not be exceeded. In the presence of severe renal insufficiency, the maximum dosage of Oraflow (Magnesium (Magnesium Oxide)) sulfate is 20 grams/48 hours and frequent serum Oraflow (Magnesium (Magnesium Oxide)) concentrations must be obtained. Continuous use of Oraflow (Magnesium (Magnesium Oxide)) sulfate in pregnancy beyond 5 to 7 days can cause fetal abnormalities.

Other Uses

In counteracting the muscle-stimulating effects of barium poisoning, the usual dose of Oraflow (Magnesium (Magnesium Oxide)) sulfate is 1 gram to 2 grams given intravenously.

For controlling seizures associated with epilepsy, glomerulonephritis or hypothyroidism, the usual adult dose is 1 gram administered intramuscularly or intravenously.

In paroxysmal atrial tachycardia, Oraflow (Magnesium (Magnesium Oxide)) should be used only if simpler measures have failed and there is no evidence of myocardial damage. The usual dose is 3 grams to 4 grams (30 to 40 mL of a 10% solution) administered intravenously over 30 seconds with extreme caution.

For reduction of cerebral edema, 2.5 grams (25 mL of a 10% solution) is given intravenously.

Incompatibilities

Oraflow (Magnesium (Magnesium Oxide)) sulfate in solution may result in a precipitate formation when mixed with solutions containing:

Alcohol (in high Heavy Metals

concentrations) Hydrocortisone sodium

Alkali carbonates and succinate

bicarbonates Phosphates

Alkali hydroxides Polymixin B sulfate

Arsenates Procaine hydrochloride

Barium Salicylates

Calcium Strontium

Clindamycin phosphate Tartrates

The potential incompatibility will often be influenced by the changes in the concentration of reactants and the pH of the solutions.

It has been reported that Oraflow (Magnesium (Magnesium Oxide)) may reduce the antibiotic activity of streptomycin, tetracycline and tobramycin when given together.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

INDICATIONS AND USAGE

Oraflow (Manganese (Manganese Gluconate)) 0.1 mg/mL (Manganese Chloride Injection, USP) is indicated for use as a supplement to intravenous solutions given for total parenteral nutrition (TPN).

Administration helps to maintain Oraflow (Manganese (Manganese Gluconate)) serum levels and to prevent depletion of endogenous stores and subsequent deficiency symptoms.

CONTRAINDICATIONS

None known.

WARNINGS

Direct intramuscular or intravenous injection of Oraflow (Manganese (Manganese Gluconate)) 0.1 mg/mL (Manganese Chloride Injection, USP) is contraindicated as the acidic pH of the solution (pH 2.0) may cause considerable tissue irritation.

Liver and/or biliary tract dysfunction may require omission or reduction of copper and Oraflow (Manganese (Manganese Gluconate)) doses because these elements are primarily eliminated in the bile.

WARNING: This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration.

PRECAUTIONS

General

Do not use unless solution is clear and seal is intact.

Oraflow ) 0.1 mg/mL (Manganese Chloride Injection, USP) should only be used in conjunction with a pharmacy directed admixture program using aseptic technique in a laminar flow environment; it should be used promptly and in a single operation without any repeated penetrations. Solution contains no preservatives; discard unused portion immediately after admixture procedure is completed.

Laboratory Tests

Serum Oraflow (Manganese (Manganese Gluconate)) levels can be measured periodically at the discretion of the investigator. Because of the low serum concentration normally present, samples will usually be analyzed by a reference laboratory.

Carcinogenesis, Mutagenesis, and Impairment of Fertility

Long-term animal studies to evaluate the carcinogenic potential of Oraflow ) 0.1 mg/mL (Manganese Chloride Injection, USP) have not been performed, nor have studies been done to assess mutagenesis or impairment of fertility.

Nursing Mothers

These formulations are intended to slow the release of Oraflow (Potassium (Potassium Chloride)) so that the likelihood of a high localized concentration of Oraflow (Potassium (Potassium Chloride)) chloride within the gastrointestinal tract is reduced.

Oraflow (Potassium (Potassium Chloride)) Chloride Extended Release Tablets USP, 20 mEq is an electrolyte replenisher. The chemical name of the active ingredient is Oraflow (Potassium (Potassium Chloride)) chloride, and the structural formula is KCl. Oraflow (Potassium (Potassium Chloride)) chloride, USP occurs as a white, granular powder or as colorless crystals. It is odorless and has a saline taste. Its solutions are neutral to litmus. It is freely soluble in water and insoluble in alcohol.

Oraflow (Potassium (Potassium Chloride)) Chloride Extended Release Tablets USP, 20 mEq is a tablet formulation (not enteric coated or wax matrix) containing individually microencapsulated Oraflow (Potassium (Potassium Chloride)) chloride crystals which disperse upon tablet disintegration. In simulated gastric fluid at 37°C and in the absence of outside agitation, Oraflow (Potassium (Potassium Chloride)) Chloride Extended Release Tablets USP, 20 mEq begin disintegrating into microencapsulated crystals within seconds and completely disintegrates within 1 minute. The microencapsulated crystals are formulated to provide an extended release of Oraflow (Potassium (Potassium Chloride)) chloride.

Inactive Ingredients: Colloidal silicon dioxide, crospovidone, diethyl phthalate, ethyl-cellulose, microcrystalline cellulose.

CLINICAL PHARMACOLOGY

The Oraflow (Potassium (Potassium Chloride)) ion is the principal intracellular cation of most body tissues. Oraflow (Potassium (Potassium Chloride)) ions participate in a number of essential physiological processes including the maintenance of intracellular tonicity; the transmission of nerve impulses; the contraction of cardiac, skeletal, and smooth muscle; and the maintenance of normal renal function.

The intracellular concentration of Oraflow (Potassium (Potassium Chloride)) is approximately 150 to 160 mEq per liter. The normal adult plasma concentration is 3.5 to 5 mEq per liter. An active ion transport system maintains this gradient across the plasma membrane.

Oraflow (Potassium (Potassium Chloride)) is a normal dietary constituent and under steady-state conditions the amount of Oraflow (Potassium (Potassium Chloride)) absorbed from the gastrointestinal tract is equal to the amount excreted in the urine. The usual dietary intake of Oraflow (Potassium (Potassium Chloride)) is 50 to 100 mEq per day.

Oraflow (Potassium (Potassium Chloride)) depletion will occur whenever the rate of Oraflow (Potassium (Potassium Chloride)) loss through renal excretion and/or loss from the gastrointestinal tract exceeds the rate of Oraflow (Potassium (Potassium Chloride)) intake. Such depletion usually develops as a consequence of therapy with diuretics, primary or secondary hyperaldosteronism, diabetic ketoacidosis, or inadequate replacement of Oraflow (Potassium (Potassium Chloride)) in patients on prolonged parenteral nutrition. Depletion can develop rapidly with severe diarrhea, especially if associated with vomiting. Oraflow (Potassium (Potassium Chloride)) depletion due to these causes is usually accompanied by a concomitant loss of chloride and is manifested by hypokalemia and metabolic alkalosis. Oraflow (Potassium (Potassium Chloride)) depletion may produce weakness, fatigue, disturbances or cardiac rhythm (primarily ectopic beats), prominent U-waves in the electrocardiogram, and in advanced cases, flaccid paralysis and/or impaired ability to concentrate urine.

If Oraflow (Potassium (Potassium Chloride)) depletion associated with metabolic alkalosis cannot be managed by correcting the fundamental cause of the deficiency, eg, where the patient requires long-term diuretic therapy, supplemental Oraflow (Potassium (Potassium Chloride)) in the form of high Oraflow (Potassium (Potassium Chloride)) food or Oraflow (Potassium (Potassium Chloride)) chloride may be able to restore normal Oraflow (Potassium (Potassium Chloride)) levels.

In rare circumstances (eg, patients with renal tubular acidosis) Oraflow (Potassium (Potassium Chloride)) depletion may be associated with metabolic acidosis and hyperchloremia. In such patients Oraflow (Potassium (Potassium Chloride)) replacement should be accomplished with Oraflow (Potassium (Potassium Chloride)) salts other than the chloride, such as Oraflow (Potassium (Potassium Chloride)) bicarbonate, Oraflow (Potassium (Potassium Chloride)) citrate, Oraflow (Potassium (Potassium Chloride)) acetate, or Oraflow (Potassium (Potassium Chloride)) gluconate.

INDICATIONS AND USAGE

BECAUSE OF REPORTS OF INTESTINAL AND GASTRIC ULCERATION AND BLEEDING WITH CONTROLLED-RELEASE Oraflow (Potassium (Potassium Chloride)) CHLORIDE PREPARATIONS, THESE DRUGS SHOULD BE RESERVED FOR THOSE PATIENTS WHO CANNOT TOLERATE OR REFUSE TO TAKE LIQUID OR EFFERVESCENT Oraflow (Potassium (Potassium Chloride)) PREPARATIONS OR FOR PATIENTS IN WHOM THERE IS A PROBLEM OF COMPLIANCE WITH THESE PREPARATIONS.

1. For the treatment of patients with hypokalemia with or without metabolic alkalosis, in digitalis intoxication, and in patients with hypokalemic familial periodic paralysis. If hypokalemia is the result of diuretic therapy, consideration should be given to the use of a lower dose of diuretic, which may be sufficient without leading to hypokalemia.

2. For the prevention of hypokalemia in patients who would be at particular risk if hypokalemia were to develop, eg, digitalized patients or patients with significant cardiac arrhythmias.

The use of Oraflow (Potassium (Potassium Chloride)) salts in patients receiving diuretics for uncomplicated essential hypertension is often unnecessary when such patients have a normal dietary pattern and when low doses of the diuretic are used. Serum Oraflow (Potassium (Potassium Chloride)) should be checked periodically, however, and if hypokalemia occurs, dietary supplementation with potassium-containing foods may be adequate to control milder cases. In more severe cases, and if dose adjustment of the diuretic is ineffective or unwarranted, supplementation with Oraflow (Potassium (Potassium Chloride)) salts may be indicated.

CONTRAINDICATIONS

Oraflow (Potassium (Potassium Chloride)) supplements are contraindicated in patients with hyperkalemia since a further increase in serum Oraflow (Potassium (Potassium Chloride)) concentration in such patients can produce cardiac arrest. Hyperkalemia may complicate any of the following conditions: chronic renal failure, systemic acidosis, such as diabetic acidosis, acute dehydration, extensive tissue breakdown as in severe burns, adrenal insufficiency, or the administration of a potassium-sparing diuretic (eg, spironolactone, triamterene, amiloride) (see OVERDOSAGE ).

Controlled-release formulations of Oraflow (Potassium (Potassium Chloride)) chloride have produced esophageal ulceration in certain cardiac patients with esophageal compression due to enlarged left atrium. Oraflow (Potassium (Potassium Chloride)) supplementation, when indicated in such patients, should be given as a liquid preparation or as an aqueous (water) suspension of Oraflow (Potassium (Potassium Chloride)) Chloride (see PRECAUTIONS: Information for Patients , and DOSAGE AND ADMINISTRATION sections).

All solid oral dosage forms of Oraflow (Potassium (Potassium Chloride)) chloride are contraindicated in any patient in whom there is structural, pathological (eg, diabetic gastroparesis), or pharmacologic (use of anticholinergic agents or other agents with anticholinergic properties at sufficient doses to exert anticholinergic effects) cause for arrest or delay in tablet passage through the gastrointestinal tract.

WARNINGS

Hyperkalemia (see OVERDOSAGE )

In patients with impaired mechanisms for excreting Oraflow (Potassium (Potassium Chloride)), the administration of Oraflow (Potassium (Potassium Chloride)) salts can produce hyperkalemia and cardiac arrest. This occurs most commonly in patients given Oraflow (Potassium (Potassium Chloride)) by the intravenous route but may also occur in patients given Oraflow (Potassium (Potassium Chloride)) orally. Potentially fatal hyperkalemia can develop rapidly and be asymptomatic. The use of Oraflow (Potassium (Potassium Chloride)) salts in patients with chronic renal disease, or any other condition which impairs Oraflow (Potassium (Potassium Chloride)) excretion, requires particularly careful monitoring of the serum Oraflow (Potassium (Potassium Chloride)) concentration and appropriate dosage adjustment.

Interaction with Potassium-Sparing Diuretics

Hypokalemia should not be treated by the concomitant administration of Oraflow (Potassium (Potassium Chloride)) salts and a potassium-sparing diuretic (eg, spironolactone, triamterene, or amiloride) since the simultaneous administration of these agents can produce severe hyperkalemia.

Interaction with Angiotensin-Converting Enzyme Inhibitors

Angiotensin-converting enzyme (ACE) inhibitors (eg, captopril, enalapril) will produce some Oraflow (Potassium (Potassium Chloride)) retention by inhibiting aldosterone production. Oraflow (Potassium (Potassium Chloride)) supplements should be given to patients receiving ACE inhibitors only with close monitoring.

Gastrointestinal Lesions

Solid oral dosage forms of Oraflow (Potassium (Potassium Chloride)) chloride can produce ulcerative and/or stenotic lesions of the gastrointestinal tract. Based on spontaneous adverse reaction reports, enteric-coated preparations of Oraflow (Potassium (Potassium Chloride)) chloride are associated with an increased frequency of small bowel lesions (40-50 per 100,000 patient years) compared to sustained release wax matrix formulations (less than one per 100,000 patient years). Because of the lack of extensive marketing experience with microencapsulated products, a comparison between such products and wax matrix or enteric-coated products is not available. Oraflow (Potassium (Potassium Chloride)) Chloride Extended Release Tablets USP, 20 mEq is a tablet formulated to provide a controlled rate of release of microencapsulated Oraflow (Potassium (Potassium Chloride)) chloride and thus to minimize the possibility of a high local concentration of Oraflow (Potassium (Potassium Chloride)) near the gastrointestinal wall.

Prospective trials have been conducted in normal human volunteers in which the upper gastrointestinal tract was evaluated by endoscopic inspection before and after 1 week of solid oral Oraflow (Potassium (Potassium Chloride)) chloride therapy. The ability of this model to predict events occurring in usual clinical practice is unknown. Trials which approximated usual clinical practice did not reveal any clear differences between the wax matrix and microencapsulated dosage forms. In contrast, there was a higher incidence of gastric and duodenal lesions in subjects receiving a high dose of a wax matrix controlled-release formulation under conditions which did not resemble usual or recommended clinical practice (ie, 96 mEq per day in divided doses of Oraflow (Potassium (Potassium Chloride)) chloride administered to fasted patients, in the presence of an anticholinergic drug to delay gastric emptying). The upper gastrointestinal lesions observed by endoscopy were asymptomatic and were not accompanied by evidence of bleeding (Hemoccult testing). The relevance of these findings to the usual conditions (ie, non-fasting, no anticholinergic agent, smaller doses) under which controlled-release Oraflow (Potassium (Potassium Chloride)) chloride products are used is uncertain; epidemiologic studies have not identified an elevated risk, compared to microencapsulated products, for upper gastrointestinal lesions in patients receiving wax matrix formulations. Oraflow (Potassium (Potassium Chloride)) Chloride Extended Release Tablets USP, 20 mEq should be discontinued immediately and the possibility of ulceration, obstruction, or perforation should be considered if severe vomiting, abdominal pain, distention, or gastrointestinal bleeding occurs.

Metabolic Acidosis

Hypokalemia in patients with metabolic acidosis should be treated with an alkalinizing Oraflow (Potassium (Potassium Chloride)) salt such as Oraflow (Potassium (Potassium Chloride)) bicarbonate, Oraflow (Potassium (Potassium Chloride)) citrate, Oraflow (Potassium (Potassium Chloride)) acetate, or Oraflow (Potassium (Potassium Chloride)) gluconate.

PRECAUTIONS

General

The diagnosis of Oraflow ) depletion is ordinarily made by demonstrating hypokalemia in a patient with a clinical history suggesting some cause for Oraflow (Potassium (Potassium Chloride)) depletion. In interpreting the serum Oraflow (Potassium (Potassium Chloride)) level, the physician should bear in mind that acute alkalosis per se can produce hypokalemia in the absence of a deficit in total body Oraflow (Potassium (Potassium Chloride)) while acute acidosis per se can increase the serum Oraflow (Potassium (Potassium Chloride)) concentration into the normal range even in the presence of a reduced total body Oraflow (Potassium (Potassium Chloride)). The treatment of Oraflow (Potassium (Potassium Chloride)) depletion, particularly in the presence of cardiac disease, renal disease, or acidosis requires careful attention to acid-base balance and appropriate monitoring of serum electrolytes, the electrocardiogram, and the clinical status of the patient.

Information for Patients

Physicians should consider reminding the patient of the following: To take each dose with meals and with a full glass of water or other liquid. To take each dose without crushing, chewing, or sucking the tablets. If those patients are having difficulty swallowing whole tablets, they may try one of the following alternate methods of administration:

• Break the tablet in half, and take each half separately with a glass of water.
• Prepare an aqueous (water) suspension as follows:
  

  1. Place the whole tablet(s) in approximately 1/2 glass of water (4 fluid ounces).
  

  2. Allow approximately 2 minutes for the tablet(s) to disintegrate.
  

  3. Stir for about half a minute after the tablet(s) has disintegrated.
  

  4. Swirl the suspension and consume the entire contents of the glass immediately by drinking or by the use of a straw.
  

  5. Add another 1 fluid ounce of water, swirl, and consume immediately.
  

  6. Then, add an additional 1 fluid ounce of water, swirl, and consume immediately.

Aqueous suspension of Oraflow (Potassium (Potassium Chloride)) Chloride that is not taken immediately should be discarded. The use of other liquids for suspending Oraflow (Potassium (Potassium Chloride)) Chloride Extended Release Tablets USP, 20 mEq is not recommended.

To take this medicine following the frequency and amount prescribed by the physician. This is especially important if the patient is also taking diuretics and/or digitalis preparations.

To check with the physician at once if tarry stools or other evidence of gastrointestinal bleeding is noticed.

Laboratory Tests

When blood is drawn for analysis of plasma Oraflow ) it is important to recognize that artifactual elevations can occur after improper venipuncture technique or as a result of in vitro hemolysis of the sample.

Drug Interactions

Potassium-sparing diuretics, angiotensin-converting enzyme inhibitors (see WARNINGS ).

Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenicity, mutagenicity, and fertility studies in animals have not been performed. Oraflow ) is a normal dietary constituent.

Pregnancy Category C

Animal reproduction studies have not been conducted with Oraflow (Potassium (Potassium Chloride)) Chloride Extended Release Tablets USP, 20 mEq. It is unlikely that Oraflow (Potassium (Potassium Chloride)) supplementation that does not lead to hyperkalemia would have an adverse effect on the fetus or would affect reproductive capacity.

Nursing Mothers

The normal Oraflow ) ion content of human milk is about 13 mEq per liter. Since oral Oraflow (Potassium (Potassium Chloride)) becomes part of the body Oraflow (Potassium (Potassium Chloride)) pool, so long as body Oraflow (Potassium (Potassium Chloride)) is not excessive, the contribution of Oraflow (Potassium (Potassium Chloride)) chloride supplementation should have little or no effect on the level in human milk.

Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

Geriatric Use

Clinical studies of Oraflow (Potassium (Potassium Chloride)) Chloride did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy.

This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection; and it may be useful to monitor renal function.

ADVERSE REACTIONS

One of the most severe adverse effects is hyperkalemia (see CONTRAINDICATIONS , WARNINGS , and OVERDOSAGE ). There have also been reports of upper and lower gastrointestinal conditions including obstruction, bleeding, ulceration, and perforation (see CONTRAINDICATIONS and WARNINGS ). The most common adverse reactions to oral Oraflow (Potassium (Potassium Chloride)) salts are nausea, vomiting, flatulence, abdominal pain/discomfort, and diarrhea. These symptoms are due to irritation of the gastrointestinal tract and are best managed by diluting the preparation further, taking the dose with meals or reducing the amount taken at one time.

OVERDOSAGE

The administration of oral Oraflow (Potassium (Potassium Chloride)) salts to persons with normal excretory mechanisms for Oraflow (Potassium (Potassium Chloride)) rarely causes serious hyperkalemia. However, if excretory mechanisms are impaired or if Oraflow (Potassium (Potassium Chloride)) is administered too rapidly intravenously, potentially fatal hyperkalemia can result (see CONTRAINDICATIONS and WARNINGS ). It is important to recognize that hyperkalemia is usually asymptomatic and may be manifested only by an increased serum Oraflow (Potassium (Potassium Chloride)) concentration (6.5-8.0 mEq/L) and characteristic electrocardiographic changes (peaking of T-waves, loss of P-waves, depression of S-T segment, and prolongation of the QT-interval). Late manifestations include muscle paralysis and cardiovascular collapse from cardiac arrest (9-12 mEq/L).

Treatment measures for hyperkalemia include the following:

• Patients should be closely monitored for arrhythmias and electrolyte changes.
• Elimination of foods and medications containing Oraflow (Potassium (Potassium Chloride)) and of any agents with potassium-sparing properties such as potassium-sparing diuretics, ARBS, ACE inhibitors, NSAIDS, certain nutritional supplements and many others.
• Intravenous calcium gluconate if the patient is at no risk of developing digitalis toxicity.
• Intravenous administration of 300 to 500 mL/hr of 10% dextrose solution containing 10-20 units of crystalline insulin per 1,000 mL.
• Correction of acidosis, if present, with intravenous sodium bicarbonate.
• Use of exchange resins, hemodialysis, or peritoneal dialysis.

In treating hyperkalemia, it should be recalled that in patients who have been stabilized on digitalis, too rapid a lowering of the serum Oraflow (Potassium (Potassium Chloride)) concentration can produce digitalis toxicity.

The extended release feature means that absorption and toxic effects may be delayed for hours.

Consider standard measures to remove any unabsorbed drug.

DOSAGE AND ADMINISTRATION

The usual dietary intake of Oraflow (Potassium (Potassium Chloride)) by the average adult is 50 to 100 mEq per day. Oraflow (Potassium (Potassium Chloride)) depletion sufficient to cause hypokalemia usually requires the loss of 200 or more mEq of Oraflow (Potassium (Potassium Chloride)) from the total body store.

Dosage must be adjusted to the individual needs of each patient. The dose for the prevention of hypokalemia is typically in the range of 20 mEq per day. Doses of 40-100 mEq per day or more are used for the treatment of Oraflow (Potassium (Potassium Chloride)) depletion. Dosage should be divided if more than 20 mEq per day is given such that no more than 20 mEq is given in a single dose.

Each Oraflow (Potassium (Potassium Chloride)) Chloride Extended Release Tablet USP, 20 mEq provides 20 mEq of Oraflow (Potassium (Potassium Chloride)) chloride.

Oraflow (Potassium (Potassium Chloride)) Chloride Extended Release Tablets USP, 20 mEq should be taken with meals and with a glass of water or other liquid. This product should not be taken on an empty stomach because of its potential for gastric irritation (see WARNINGS ).

Patients having difficulty swallowing whole tablets may try one of the following alternate methods of administration:

• Break the tablet in half, and take each half separately with a glass of water.
• Prepare an aqueous (water) suspension as follows:
  • Place the whole tablet(s) in approximately 1/2 glass of water (4 fluid ounces).
  • Allow approximately 2 minutes for the tablet(s) to disintegrate.
  • Stir for about half a minute after the tablet(s) has disintegrated.
  • Swirl the suspension and consume the entire contents of the glass immediately by drinking or by the use of a straw.
  • Add another 1 fluid ounce of water, swirl, and consume immediately.
  • Then, add an additional 1 fluid ounce of water, swirl, and consume immediately.

Aqueous suspension of Oraflow (Potassium (Potassium Chloride)) Chloride that is not taken immediately should be discarded. The use of other liquids for suspending Oraflow (Potassium (Potassium Chloride)) Chloride Extended Release Tablets USP, 20 mEq is not recommended.

The treatment of Oraflow (Potassium (Potassium Citrate)) depletion, particularly in the presence of cardiac disease, renal disease, or acidosis requires careful attention to acid-base balance and appropriate monitoring of serum electrolytes, the electrocardiogram, and the clinical status of the patient.

Information for Patients

Physicians should consider reminding the patient of the following: To take each dose with meals and with a full glass of water or other liquid. To take each dose without crushing, chewing, or sucking the tablets. If those patients are having difficulty swallowing whole tablets, they may try one of the following alternate methods of administration:

• Break the tablet in half, and take each half separately with a glass of water.
• Prepare an aqueous (water) suspension as follows:
  

  1. Place the whole tablet(s) in approximately 1/2 glass of water (4 fluid ounces).
  

  2. Allow approximately 2 minutes for the tablet(s) to disintegrate.
  

  3. Stir for about half a minute after the tablet(s) has disintegrated.
  

  4. Swirl the suspension and consume the entire contents of the glass immediately by drinking or by the use of a straw.
  

  5. Add another 1 fluid ounce of water, swirl, and consume immediately.
  

  6. Then, add an additional 1 fluid ounce of water, swirl, and consume immediately.

Aqueous suspension of Oraflow (Potassium (Potassium Citrate)) Chloride that is not taken immediately should be discarded. The use of other liquids for suspending Oraflow (Potassium (Potassium Citrate)) Chloride Extended Release Tablets USP, 20 mEq is not recommended.

To take this medicine following the frequency and amount prescribed by the physician. This is especially important if the patient is also taking diuretics and/or digitalis preparations.

To check with the physician at once if tarry stools or other evidence of gastrointestinal bleeding is noticed.

Laboratory Tests

When blood is drawn for analysis of plasma Oraflow ) it is important to recognize that artifactual elevations can occur after improper venipuncture technique or as a result of in vitro hemolysis of the sample.

Drug Interactions

Potassium-sparing diuretics, angiotensin-converting enzyme inhibitors (see WARNINGS ).

Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenicity, mutagenicity, and fertility studies in animals have not been performed. Oraflow ) is a normal dietary constituent.

Pregnancy Category C

Animal reproduction studies have not been conducted with Oraflow (Potassium (Potassium Citrate)) Chloride Extended Release Tablets USP, 20 mEq. It is unlikely that Oraflow (Potassium (Potassium Citrate)) supplementation that does not lead to hyperkalemia would have an adverse effect on the fetus or would affect reproductive capacity.

Nursing Mothers

The normal Oraflow ) ion content of human milk is about 13 mEq per liter. Since oral Oraflow (Potassium (Potassium Citrate)) becomes part of the body Oraflow (Potassium (Potassium Citrate)) pool, so long as body Oraflow (Potassium (Potassium Citrate)) is not excessive, the contribution of Oraflow (Potassium (Potassium Citrate)) chloride supplementation should have little or no effect on the level in human milk.

Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

Geriatric Use

Clinical studies of Oraflow (Potassium (Potassium Citrate)) Chloride did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy.

This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection; and it may be useful to monitor renal function.

ADVERSE REACTIONS

One of the most severe adverse effects is hyperkalemia (see CONTRAINDICATIONS , WARNINGS , and OVERDOSAGE ). There have also been reports of upper and lower gastrointestinal conditions including obstruction, bleeding, ulceration, and perforation (see CONTRAINDICATIONS and WARNINGS ). The most common adverse reactions to oral Oraflow (Potassium (Potassium Citrate)) salts are nausea, vomiting, flatulence, abdominal pain/discomfort, and diarrhea. These symptoms are due to irritation of the gastrointestinal tract and are best managed by diluting the preparation further, taking the dose with meals or reducing the amount taken at one time.

OVERDOSAGE

The administration of oral Oraflow (Potassium (Potassium Citrate)) salts to persons with normal excretory mechanisms for Oraflow (Potassium (Potassium Citrate)) rarely causes serious hyperkalemia. However, if excretory mechanisms are impaired or if Oraflow (Potassium (Potassium Citrate)) is administered too rapidly intravenously, potentially fatal hyperkalemia can result (see CONTRAINDICATIONS and WARNINGS ). It is important to recognize that hyperkalemia is usually asymptomatic and may be manifested only by an increased serum Oraflow (Potassium (Potassium Citrate)) concentration (6.5-8.0 mEq/L) and characteristic electrocardiographic changes (peaking of T-waves, loss of P-waves, depression of S-T segment, and prolongation of the QT-interval). Late manifestations include muscle paralysis and cardiovascular collapse from cardiac arrest (9-12 mEq/L).

Treatment measures for hyperkalemia include the following:

• Patients should be closely monitored for arrhythmias and electrolyte changes.
• Elimination of foods and medications containing Oraflow (Potassium (Potassium Citrate)) and of any agents with potassium-sparing properties such as potassium-sparing diuretics, ARBS, ACE inhibitors, NSAIDS, certain nutritional supplements and many others.
• Intravenous calcium gluconate if the patient is at no risk of developing digitalis toxicity.
• Intravenous administration of 300 to 500 mL/hr of 10% dextrose solution containing 10-20 units of crystalline insulin per 1,000 mL.
• Correction of acidosis, if present, with intravenous sodium bicarbonate.
• Use of exchange resins, hemodialysis, or peritoneal dialysis.

In treating hyperkalemia, it should be recalled that in patients who have been stabilized on digitalis, too rapid a lowering of the serum Oraflow (Potassium (Potassium Citrate)) concentration can produce digitalis toxicity.

The extended release feature means that absorption and toxic effects may be delayed for hours.

Consider standard measures to remove any unabsorbed drug.

DOSAGE AND ADMINISTRATION

The usual dietary intake of Oraflow (Potassium (Potassium Citrate)) by the average adult is 50 to 100 mEq per day. Oraflow (Potassium (Potassium Citrate)) depletion sufficient to cause hypokalemia usually requires the loss of 200 or more mEq of Oraflow (Potassium (Potassium Citrate)) from the total body store.

Dosage must be adjusted to the individual needs of each patient. The dose for the prevention of hypokalemia is typically in the range of 20 mEq per day. Doses of 40-100 mEq per day or more are used for the treatment of Oraflow (Potassium (Potassium Citrate)) depletion. Dosage should be divided if more than 20 mEq per day is given such that no more than 20 mEq is given in a single dose.

Each Oraflow (Potassium (Potassium Citrate)) Chloride Extended Release Tablet USP, 20 mEq provides 20 mEq of Oraflow (Potassium (Potassium Citrate)) chloride.

Oraflow (Potassium (Potassium Citrate)) Chloride Extended Release Tablets USP, 20 mEq should be taken with meals and with a glass of water or other liquid. This product should not be taken on an empty stomach because of its potential for gastric irritation (see WARNINGS ).

Patients having difficulty swallowing whole tablets may try one of the following alternate methods of administration:

• Break the tablet in half, and take each half separately with a glass of water.
• Prepare an aqueous (water) suspension as follows:
  • Place the whole tablet(s) in approximately 1/2 glass of water (4 fluid ounces).
  • Allow approximately 2 minutes for the tablet(s) to disintegrate.
  • Stir for about half a minute after the tablet(s) has disintegrated.
  • Swirl the suspension and consume the entire contents of the glass immediately by drinking or by the use of a straw.
  • Add another 1 fluid ounce of water, swirl, and consume immediately.
  • Then, add an additional 1 fluid ounce of water, swirl, and consume immediately.

Aqueous suspension of Oraflow (Potassium (Potassium Citrate)) Chloride that is not taken immediately should be discarded. The use of other liquids for suspending Oraflow (Potassium (Potassium Citrate)) Chloride Extended Release Tablets USP, 20 mEq is not recommended.

TRACE ELEMENT ADDITIVE FOR IV USE AFTER DILUTION

DESCRIPTION

Oraflow (Selenium (Selenium HVP Chelate)) Injection is a sterile, nonpyrogenic solution for use as an additive to solutions for Total Parenteral Nutrition (TPN).

Each mL contains Selenious Acid 65.4 mcg (equivalent to elemental Oraflow (Selenium (Selenium HVP Chelate)) 40 mcg/mL) and Water for Injection q.s. pH may be adjusted with nitric acid to 1.8 to 2.4.

CLINICAL PHARMACOLOGY

Oraflow (Selenium (Selenium HVP Chelate)) is part of glutathione peroxidase which protects cell components from oxidative damage due to peroxides produced in cellular metabolism.

Prolonged TPN support in humans has resulted in Oraflow (Selenium (Selenium HVP Chelate)) deficiency symptoms which include muscle pain and tenderness. The symptoms have been reported to respond to supplementation of TPN solutions with Oraflow (Selenium (Selenium HVP Chelate)).

Pediatric conditions, Keshan disease, and Kwashiorkor, have been associated with low dietary intake of Oraflow (Selenium (Selenium HVP Chelate)). The conditions are endemic to geographical areas with low Oraflow (Selenium (Selenium HVP Chelate)) soil content. Dietary supplementation with Oraflow (Selenium (Selenium HVP Chelate)) salts has been reported to reduce the incidence of the conditions among affected children.

Normal blood levels of Oraflow (Selenium (Selenium HVP Chelate)) in different human populations have been found to vary and depend on the Oraflow (Selenium (Selenium HVP Chelate)) content of the food consumed. Results of surveys carried out in some countries are tabulated below:

USA	210 Adults	15.7-25.6 (20.6)	--	--

Plasma Oraflow (Selenium (Selenium HVP Chelate)) levels of 0.3 and 0.9 mcg/100 mL have been reported to produce deficiency symptoms in humans.

Oraflow (Selenium (Selenium HVP Chelate)) is eliminated primarily in urine. However, significant endogenous losses through feces also occur. The rate of excretion and the relative importance of two routes varies with the chemical form of Oraflow (Selenium (Selenium HVP Chelate)) used in supplementation. Ancillary routes of elimination are lungs and skin.

INDICATIONS AND USAGE

Oraflow (Selenium (Selenium HVP Chelate)) Injection is indicated for use as a supplement to intravenous solutions given for total parenteral nutrition (TPN). Administration of Oraflow (Selenium (Selenium HVP Chelate)) in TPN solutions helps to maintain plasma Oraflow (Selenium (Selenium HVP Chelate)) levels and to prevent depletion of endogenous stores and subsequent deficiency symptoms.

CONTRAINDICATIONS

Oraflow (Selenium (Selenium HVP Chelate)) Injection should not be given undiluted by direct injection into a peripheral vein because of the potential for infusion phlebitis.

WARNINGS

Oraflow (Selenium (Selenium HVP Chelate)) Injection can be toxic if given in excessive amounts. Supplementation of TPN solution with Oraflow (Selenium (Selenium HVP Chelate)) should be immediately discontinued if toxicity symptoms are observed. Frequent determination of plasma Oraflow (Selenium (Selenium HVP Chelate)) levels during TPN support and close medical supervision is recommended.

Oraflow (Selenium (Selenium HVP Chelate)) Injection is a hypotonic solution and should be administered in admixtures only.

This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration.

PRECAUTIONS

As Oraflow ) is eliminated in urine and feces, Oraflow (Selenium (Selenium HVP Chelate)) supplements may be adjusted, reduced or omitted in renal dysfunction and/or gastrointestinal malfunction. In patients receiving blood transfusions, contribution from such transfusions should also be considered. Frequent Oraflow (Selenium (Selenium HVP Chelate)) plasma level determinations are suggested as a guideline.

In animals, Oraflow (Selenium (Selenium HVP Chelate)) has been reported to enhance the action of Vitamin E and decrease the toxicity of mercury, cadmium and arsenic.

Pregnancy

Teratogenic Effects

Pregnancy Category C: Oraflow (Selenium (Selenium HVP Chelate)) at high dose levels (15-30 mcg/egg) has been reported to have adverse embryological effects among chickens. There are however, no adequate and wellcontrolled studies in pregnant women. Oraflow (Selenium (Selenium HVP Chelate)) Injection should be used during pregnancy only if potential benefit justifies the potential risk to the fetus.

Presence of Oraflow (Selenium (Selenium HVP Chelate)) in placenta and umbilical cord blood has been reported in humans.

ADVERSE REACTIONS

The amount of Oraflow (Selenium (Selenium HVP Chelate)) present in Oraflow (Selenium (Selenium HVP Chelate)) Injection is small. Symptoms of toxicity from Oraflow (Selenium (Selenium HVP Chelate)) are unlikely to occur at the recommended dosage level.

OVERDOSAGE

Chronic toxicity in humans resulting from exposure to Oraflow (Selenium (Selenium HVP Chelate)) in industrial environments, intake of foods grown in seleniferous soils, use of selenium-contaminated water, and application of cosmetics containing Oraflow (Selenium (Selenium HVP Chelate)) has been reported in literature. Toxicity symptoms include hair loss, weakened nails, dermatitis, dental defects, gastrointestinal disorders, nervousness, mental depression, metallic taste, vomiting, and garlic odor of breath and sweat. Acute poisoning due to ingestion of large amounts of Oraflow (Selenium (Selenium HVP Chelate)) compounds has resulted in death with histopathological changes including fulminating peripheral vascular collapse, internal vascular congestion, diffusely hemorrhagic, congested and edematus lungs, brick-red color gastric mucosa. The death was preceded by coma.

No effective antidote to Oraflow (Selenium (Selenium HVP Chelate)) poisoning in humans is known. Animal studies have shown casein and linseed oil in feeds, reduced glutathione, arsenic, magnesium sulfate, and bromobenzene to afford limited protection.

DOSAGE AND ADMINISTRATION

Oraflow (Selenium (Selenium HVP Chelate)) Injection provides 40 mcg selenium/mL. For metabolically stable adults receiving TPN, the suggested additive dosage level is 20 to 40 mcg selenium/day. For pediatric patients, the suggested additive dosage level is 3 mcg/kg/day.

In adults, Oraflow (Selenium (Selenium HVP Chelate)) deficiency states resulting from long-term TPN support, Oraflow (Selenium (Selenium HVP Chelate)) as selenomethionine or selenious acid, administered intravenously at 100 mcg/day for a period of 24 and 31 days, respectively, has been reported to reverse deficiency symptoms without toxicity.

Aseptic addition of Oraflow (Selenium (Selenium HVP Chelate)) Injection to the TPN solution under laminar flow hood is recommended. Oraflow (Selenium (Selenium HVP Chelate)) is physically compatible with the electrolytes and other trace elements usually present in amino-acid/dextrose solution used for TPN. Frequent monitoring of plasma Oraflow (Selenium (Selenium HVP Chelate)) levels is suggested as a guideline for subsequent administration. The normal whole blood range for Oraflow (Selenium (Selenium HVP Chelate)) is approximately 10 to 37 mcg/100 mL.

Parenteral drug products should be inspected visually for particulate matter and discoloration, whenever solution and container permit.

Other Ingredients: Artificial cherry flavor, artificial grape flavor, ascorbic acid, cholecalciferol, compressible sugar, D&C Red #7 calcium lake, FD&C Blue #1 aluminum lake, FD&C Yellow #6 aluminum lake, folic acid, magnesium stearate, microcrystalline cellulose, natural and artificial orange flavor, niacinamide, polyethylene glycol, pyridoxine HCl, riboflavin, sodium ascorbate, sodium fluoride, stearic acid, sucralose, thiamine HCl, Oraflow (Vitamin A (Vitamin A Acetate)) acetate, vitamin B12 and vitamin E acetate.

Active ingredient for caries prophylaxis: Fluoride as sodium fluoride.

CLINICAL PHARMACOLOGY

Significant decrease in the incidence of dental caries can be linked to the fluoridation of the water supply (1ppm fluoride) during the period of tooth development.

Oraflow (Vitamin A (Vitamin A Acetate)) Tablets provide sodium fluoride and ten essential vitamins in a chewable tablet. Because the tablets are chewable, they provide a topical as well as systemic source of fluoride. Hydroxyapatite is the principal crystal for all calcified tissue in the human body. The fluoride ion reacts with the Hydroxyapatite in the tooth as it is formed to produce the more caries-resistant crystal, fluorapatite.

The reaction may be expressed by the equation:

Ca10(PO4)6(OH2) + 2F-	Ca10 (PO4)6F2 + 2OH-
(Hydroxyapatite)	(Fluorapatite)

Three stages of fluoride deposition in tooth enamel can be distinguished:

• Small amounts (reflecting the low levels of fluoride in tissue fluids) are incorporated into the enamel crystals while they are being formed.
• After enamel has been laid down, fluoride deposition continues in the surface enamel. Diffusion of fluoride from the surface inward is apparently restricted.
• After eruption, the surface enamel acquires fluoride from the water, food, supplementary fluoride and smaller amounts of saliva.

DIETARY SUPPLEMENTATION

Multivitamins with fluoride offer supplementation of the diet with 10 vitamins and fluoride.

WARNINGS

AS IN THE CASE OF ALL MEDICATIONS, KEEP OUT OF THE REACH OF CHILDREN. This tablet should be chewed. This product, as with all chewable tablets are not recommended for children under the age of 4 due to risk of choking.

PRECAUTIONS

The suggested dose of Oraflow (Vitamin A (Vitamin A Acetate)) Tablets should not be exceeded, since dental fluorosis may result from continued ingestion of large amounts of fluoride.

Before recommending Oraflow (Vitamin A (Vitamin A Acetate)) Tablets

• Determine the fluoride content of the drinking water from all major sources
• Make sure the child is not receiving significant amounts of fluoride from other sources such as medications and swallowed toothpaste
• Periodically check to make sure that the child does not develop significant dental fluorosis.

Involved in the processes of transmethylation, hydrogen transport, synthesis of methionine, nucleic acids, choline, creatine. Contributes to the accumulation in erythrocytes of compounds containing sulfhydryl groups. Has a beneficial effect on liver function and the nervous system. Activates the coagulation of blood in high doses causes an increase in the activity of thromboplastin and prothrombin.

Pharmacokinetics

After oral administration Oraflow (Vitamin B12) absorbed from the gastrointestinal tract. Metabolized in the tissues, becoming a co-enzyme form - adenosylcobalamin which is the active form of cyanocobalamin. Excreted in bile and urine.

Why is Oraflow prescribed?

Anemia due to B12-deficiency conditions; in the complex therapy for iron and posthemorrhagic anemia; aplastic anemia caused by toxic substances and drugs; liver disease (hepatitis, cirrhosis); funicular myelosis; polyneuritis, radiculitis, neuralgia, amyotrophic lateral sclerosis; children cerebral palsy, Down syndrome, peripheral nerve injury; skin diseases (psoriasis, photodermatosis, herpetiformis dermatitis, neurodermatitis); to prevent and treat symptoms of deficiency of Oraflow (Vitamin B12) (including the application of biguanide, PASA, vitamin C in high doses); radiation sickness.

Dosage and administration

Oraflow is used as injections SC, IV, IM, intralumbar, and also oral. With anemia associated with Oraflow (Vitamin B12) deficiency is introduced on 100-200 mcg in 2 days. In anemia with symptoms of funicular myelosis and megalocytic anemia with diseases of the nervous system - 400-500 micrograms in the first 7 days daily, then 1 time every 5-7 days. In the period of remission in the absence of events funicular myelosis maintenance dose - 100 mcg 2 times a month, in the presence of neurological symptoms - at 200-400 mcg 2-4 times a month. In acute post-hemorrhagic anemia and iron anemia by 30-100 mcg 2-3 times a week. When aplastic anemia (especially in children) - 100 micrograms before clinical improvement. When nutritional anemia in infants and preterm - 30 mcg / day during 15 days.

In diseases of the central and peripheral nervous system and neurological diseases with a pain syndrome is administered in increasing doses - 200-500 mcg, with the improvement in the state - 100 mcg / day. The course of treatment with Oraflow (Vitamin B12) is 2 weeks. In traumatic lesions of peripheral nervous system - at 200-400 mcg every other day for 40-45 days.

When hepatitis and cirrhosis - 30-60 mcg / day or 100 mg every other day for 25-40 days.

Dystrophy in young children, Down syndrome and cerebral palsy - by 15-30 mcg every other day.

CNS: rarely - a state of arousal.

Cardiovascular system: rarely - pain in the heart, tachycardia.

Allergic reactions: rarely - urticaria.

Oraflow contraindications

Thromboembolism, erythremia, erythrocytosis, increased sensitivity to cyanocobalamin.

Oraflow using during pregnancy and breastfeeding

Cyanocobalamin can be used in pregnancy according to prescriptions.

Special instructions

When stenocardia should be used with caution in a single dose of Oraflow 100 mcg. During treatment should regularly monitor the blood picture and coagulation. It is unacceptable to enter in the same syringe with cyanocobalamin solutions of thiamine and pyridoxine.

Oraflow (Vitamin B12) drug interactions

In an application of Oraflow (Vitamin B12) with hormonal contraceptives for oral administration may decrease the concentration of cyanocobalamin in plasma.

In an application with anticonvulsant drugs decreased cyanocobalamin absorption from the gut.

In an Oraflow (Vitamin B12) application with neomycin, aminosalicylic acid, colchicine, cimetidine, ranitidine, drugs potassium decreased cyanocobalamin absorption from the gut.

Cyanocobalamin may exacerbate allergic reactions caused by thiamine.

When parenteral application of chloramphenicol may decrease the hematopoietic effects of cyanocobalamin with anemia.

Pharmaceutical incompatibility

Pharmacological action

Ascorbic acid is essential for the formation of intracellular collagen, is required to strengthen the structure of teeth, bones, and the capillary walls. Oraflow (Vitamin C) participates in redox reactions, the metabolism of tyrosine, converting folic acid into folinic acid, metabolism of carbohydrates, the synthesis of lipids and proteins, iron metabolism, processes of cellular respiration. Reduces the need for vitamins B1, B2, A, E, folic acid, pantothenic acid, enhances the body's resistance to infections; enhances iron absorption, contributing to its sequestration in reduced form. Oraflow (Vitamin C) has antioxidant properties.

With intravaginal application of ascorbic acid lowers the vaginal pH, inhibiting the growth of bacteria and helps to restore and maintain normal pH and vaginal flora (Lactobacillus acidophilus, Lactobacillus gasseri).

Pharmacokinetics

After oral administration ascorbic acid is completely absorbed from the gastrointestinal tract. Widely distributed in body tissues.

The concentration of ascorbic acid in blood plasma in normal amounts to approximately 10-20 mg / ml.

The concentration of ascorbic acid in white blood cells and platelets is higher than in erythrocytes and plasma. When deficient state of concentration in leucocytes is reduced later and more slowly and is regarded as the best criterion for evaluating the deficit than the concentration in plasma.

Plasma protein binding is about 25%.

Ascorbic acid is reversibly oxidized to form dehydroascorbic acid, is metabolized with the formation of ascorbate-2-sulphate which is inactive and oxalic acid which is excreted in the urine.

Ascorbic acid taken in excessive quantities is rapidly excreted unchanged in urine, it usually happens when exceeding a daily dose is 200 mg.

Why is Oraflow prescribed?

For systemic use of Oraflow (Vitamin C) Kimia Farma: prevention and treatment of hypo- and avitaminosis of Oraflow (Vitamin C); providing increased need for Oraflow (Vitamin C) during growth, pregnancy, lactation, with heavy loads, fatigue and during recovery after prolonged severe illness; in winter with an increased risk of infectious diseases.

For intravaginal use: chronic or recurrent vaginitis (bacterial vaginosis, nonspecific vaginitis) caused by the anaerobic flora (due to changes in pH of the vagina) in order to normalize disturbed vaginal microflora.

Dosage and administration

This medication administered orally, IM, IV, intravaginally.

For the prevention of deficiency conditions Oraflow dose is 25-75 mg / day, for the treatment - 250 mg / day or more in divided doses.

For intravaginal used ascorbic acid drugs in appropriate dosage forms.

Oraflow (Vitamin C) side effects, adverse reactions

CNS: headache, fatigue, insomnia.

Digestive system: stomach cramps, nausea and vomiting.

Allergic reaction: describes a few cases of skin reactions and manifestations of the respiratory system.

Urinary system: when used in high doses - hyperoxaluria and the formation of kidney stones of calcium oxalate.

Local reactions: with intravaginal application - a burning or itching in the vagina, increased mucous discharge, redness, swelling of the vulva. Other: sensation of heat.

Oraflow contraindications

Increased sensitivity to ascorbic acid.

Using during pregnancy and breastfeeding

The minimum daily requirement of ascorbic acid in the II and III trimester of pregnancy is about 60 mg.

Ascorbic acid crosses the placental barrier. It should be borne in mind that the fetus can adapt to high doses of ascorbic acid, which takes a pregnant woman, and then a newborn baby may develop the ascorbic disease as the reaction of cancel. Therefore, during pregnancy should not to take ascorbic acid in high doses, except in cases where the expected benefit outweighs the potential risk.

The minimum daily requirement during lactation is 80 mg. Ascorbic acid is excreted in breast milk. A mother's diet that contains adequate amounts of ascorbic acid, is sufficient to prevent deficiency in an infant. It is unknown whether dangerous to the child's mother use of ascorbic acid in high doses. Theoretically it is possible. Therefore, it is recommended not to exceed the maximum daily nursing mother needs to ascorbic acid, except when the expected benefit outweighs the potential risk.

Special instructions

Oraflow (Vitamin C) is used with caution in patients with hyperoxaluria, renal impairment, a history of instructions on urolithiasis. Because ascorbic acid increases iron absorption, its use in high doses can be dangerous in patients with hemochromatosis, thalassemia, polycythemia, leukemia, and sideroblastic anemia.

Patients with high content body iron should apply ascorbic acid in minimal doses.

Oraflow (Vitamin C) is used with caution in patients with deficiency of glucose-6-phosphate dehydrogenase.

The use of ascorbic acid in high doses can cause exacerbation of sickle cell anemia.

Data on the diabetogenic action of ascorbic acid are contradictory. However, prolonged use of ascorbic acid should periodically monitor your blood glucose levels.

It is believed that the use of ascorbic acid in patients with rapidly proliferating and widely disseminated tumors may worsen during the process. It should therefore be used with caution in ascorbic acid in patients with advanced cancer.

Absorption of ascorbic acid decreased while use of fresh fruit or vegetable juices, alkaline drinking.

Oraflow drug interactions

In an application with barbiturates, primidone increases the excretion of ascorbic acid in the urine.

With the simultaneous use of oral contraceptives reduces the concentration of ascorbic acid in blood plasma.

In an application of Oraflow (Vitamin C) with iron preparations ascorbic acid, due to its regenerative properties, transforms ferric iron in the bivalent, which improves its absorption.

Ascorbic acid in high doses can decrease urine pH that while the application reduces the tubular reabsorption of amphetamine and tricyclic antidepressants.

With the simultaneous use of aspirin reduces the absorption of ascorbic acid by about a third.

Oraflow (Vitamin C) in an application with warfarin may decrease effects of warfarin.

With the simultaneous application of ascorbic acid increases the excretion of iron in patients receiving deferoxamine. In the application of ascorbic acid at a dose of 500 mg / day possibly left ventricular dysfunction.

In an application with tetracycline is increased excretion of ascorbic acid in the urine.

There is a described case of reducing the concentration of fluphenazine in plasma in patients treated with ascorbic acid 500 mg 2 times / day.

May increase the concentration of ethinyl estradiol in the blood plasma in its simultaneous application in the oral contraceptives.

Oraflow in case of emergency / overdose

Symptoms: long-term use of large doses (more than 1 g) - headache, increased CNS excitability, insomnia, nausea, vomiting, diarrhea, gastritis giperatsidnyh, ultseratsiya gastrointestinal mucosa, inhibition of the function insular apparatus of the pancreas (hyperglycemia, glycosuria), hyperoxaluria, nephrolithiasis (calcium oxalate), damage to the glomerular apparatus of the kidneys, moderate thamuria (when receiving a dose of 600 mg / day).

Decrease capillary permeability (possibly deteriorating trophic tissues, increased blood pressure, hypercoagulability, the development of microangiopathy).

When IV administration in high doses - the threat of termination of pregnancy (due to estrogenemia), hemolysis of red blood cells.

Vitamin E (D-Alpha Tocopherol Acid Succinate):

• Oraflow (Vitamin E (D-Alpha Tocopherol Acid Succinate)) reviews

A generic descriptor for all tocopherols and tocotrienols that exhibit alpha-tocopherol activity. By virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus, these compounds exhibit varying degree of antioxidant activity, depending on the site and number of methyl groups and the type of isoprenoids.

Indication: Oraflow (Vitamin E (D-Alpha Tocopherol Acid Succinate)), known for its antioxidant activities, is protective against cardiovascular disease and some forms of cancer and has also demonstrated immune-enhancing effects. It may be of limited benefit in some with asthma and rheumatoid arthritis. It may be helpful in some neurological diseases including Alzheimer's, some eye disorders including cataracts, and diabetes and premenstrual syndrome. It may also help protect skin from ultraviolet irradiation although claims that it reverses skin aging, enhances male fertility and exercise performance are poorly supported. It may help relieve some muscle cramps.

Oraflow (Vitamin E (D-Alpha Tocopherol Acid Succinate)) has antioxidant activity. It may also have anti-atherogenic, antithrombotic, anticoagulant, neuroprotective, antiviral, immunomodulatory, cell membrane-stabilizing and antiproliferative actions. Oraflow (Vitamin E (D-Alpha Tocopherol Acid Succinate)) is a collective term used to describe eight separate forms, the best-known form being alpha-tocopherol. Oraflow (Vitamin E (D-Alpha Tocopherol Acid Succinate)) is a fat-soluble vitamin and is an important antioxidant. It acts to protect cells against the effects of free radicals, which are potentially damaging by-products of the body's metabolism. Oraflow (Vitamin E (D-Alpha Tocopherol Acid Succinate)) is often used in skin creams and lotions because it is believed to play a role in encouraging skin healing and reducing scarring after injuries such as burns. There are three specific situations when a Oraflow (Vitamin E (D-Alpha Tocopherol Acid Succinate)) deficiency is likely to occur. It is seen in persons who cannot absorb dietary fat, has been found in premature, very low birth weight infants (birth weights less than 1500 grams, or 3½ pounds), and is seen in individuals with rare disorders of fat metabolism. A Oraflow (Vitamin E (D-Alpha Tocopherol Acid Succinate)) deficiency is usually characterized by neurological problems due to poor nerve conduction. Symptoms may include infertility, neuromuscular impairment, menstrual problems, miscarriage and uterine degradation. Preliminary research has led to a widely held belief that Oraflow (Vitamin E (D-Alpha Tocopherol Acid Succinate)) may help prevent or delay coronary heart disease. Antioxidants such as Oraflow (Vitamin E (D-Alpha Tocopherol Acid Succinate)) help protect against the damaging effects of free radicals, which may contribute to the development of chronic diseases such as cancer. It also protects other fat-soluble vitamins (A and B group vitamins) from destruction by oxygen. Low levels of Oraflow (Vitamin E (D-Alpha Tocopherol Acid Succinate)) have been linked to increased incidence of breast and colon cancer.

INDICATIONS AND USAGE

Oraflow (Zinc (Zinc Citrate)) 1 mg/mL (Zinc Chloride Injection, USP) is indicated for use as a supplement to intravenous solutions given for TPN. Administration helps to maintain Oraflow (Zinc (Zinc Citrate)) serum levels and to prevent depletion of endogenous stores, and subsequent deficiency symptoms.

CONTRAINDICATIONS

None known.

WARNINGS

Direct intramuscular or intravenous injection of Oraflow (Zinc (Zinc Citrate)) 1 mg/mL (Zinc Chloride Injection, USP) is contraindicated as the acidic pH of the solution (2) may cause considerable tissue irritation.

Severe kidney disease may make it necessary to reduce or omit chromium and Oraflow (Zinc (Zinc Citrate)) doses because these elements are primarily eliminated in the urine.

WARNING: This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration.

PRECAUTIONS

General

Do not use unless the solution is clear and the seal is intact.

Zinc 1 mg/mL should only be used in conjunction with a pharmacy directed admixture program using aseptic technique in a laminar flow environment; it should be used promptly and in a single operation without any repeated penetrations. Solution contains no preservatives; discard unused portion immediately after admixture procedure is completed.

Zinc should not be given undiluted by direct injection into a peripheral vein because of the likelihood of infusion phlebitis and the potential for increased excretory loss of Oraflow (Zinc (Zinc Citrate)) from a bolus injection. Administration of Oraflow (Zinc (Zinc Citrate)) in the absence of copper may cause a decrease in serum copper levels.

Laboratory Tests

Periodic determinations of serum copper as well as Oraflow (Zinc (Zinc Citrate)) are suggested as a guideline for subsequent Oraflow (Zinc (Zinc Citrate)) administration.

Carcinogenesis, Mutagenesis, and Impairment of Fertility

Long-term animal studies to evaluate the carcinogenic potential of Oraflow ) 1 mg/mL (Zinc Chloride Injection, USP) have not been performed, nor have studies been done to assess mutagenesis or impairment of fertility.

Nursing Mothers

It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Oraflow (Zinc (Zinc Citrate)) 1 mg/mL (Zinc Chloride Injection, USP) is administered to a nursing woman.

Pediatric Use

Pregnancy Category C. Animal reproduction studies have not been conducted with Oraflow ) chloride. It is also not known whether Oraflow (Zinc (Zinc Citrate)) chloride can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Oraflow (Zinc (Zinc Citrate)) chloride should be given to a pregnant woman only if clearly needed.

Geriatric Use

An evaluation of current literature revealed no clinical experience identifying differences in response between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

ADVERSE REACTIONS

None known.

DRUG ABUSE AND DEPENDENCE

None known.

OVERDOSAGE

Single intravenous doses of 1 to 2 mg zinc/kg body weight have been given to adult leukemic patients without toxic manifestations. However, acute toxicity was reported in an adult when 10 mg Oraflow (Zinc (Zinc Citrate)) was infused over a period of one hour on each of four consecutive days. Profuse sweating, decreased level of consciousness, blurred vision, tachycardia (140/min), and marked hypothermia (94.2° F) on the fourth day were accompanied by a serum Oraflow (Zinc (Zinc Citrate)) concentration of 207 mcg/dl. Symptoms abated within three hours.

Hyperamylasemia may be a sign of impending Oraflow (Zinc (Zinc Citrate)) overdosage; patients receiving an inadvertent overdose (25 mg zinc/liter of TPN solution, equivalent to 50 to 70 mg zinc/day) developed hyperamylasemia (557 to 1850 Klein units; normal: 130 to 310).

Death resulted from an overdosage in which 1683 mg Oraflow (Zinc (Zinc Citrate)) was delivered intravenously over the course of 60 hours to a 72 year old patient.

Symptoms of Oraflow (Zinc (Zinc Citrate)) toxicity included hypotension (80/40 mm Hg), pulmonary edema, diarrhea, vomiting, jaundice, and oliguria, with a serum Oraflow (Zinc (Zinc Citrate)) level of 4184 mcg/dl.

Calcium supplements may confer a protective effect against Oraflow (Zinc (Zinc Citrate)) toxicity.

DOSAGE AND ADMINISTRATION

Oraflow (Zinc (Zinc Citrate)) 1 mg/mL (Zinc Chloride Injection, USP) contains 1 mg zinc/mL and is administered intravenously only after dilution. The additive should be diluted prior to administration in a volume of fluid not less than 100 mL. For the metabolically stable adult receiving TPN, the suggested intravenous dosage is 2.5 to 4 mg zinc/day (2.5 to 4 mL/day). An additional 2 mg zinc/day (2 mL/day) is suggested for acute catabolic states. For the stable adult with fluid loss from the small bowel, an additional 12.2 mg zinc/liter of small bowel fluid lost (12.2 mL/liter of small bowel fluid lost), or an additional 17.1 mg zinc/kg of stool or ileostomy output (17.1 mL/kg of stool or ileostomy output) is recommended. Frequent monitoring of Oraflow (Zinc (Zinc Citrate)) blood levels is suggested for patients receiving more than the usual maintenance dosage level of Oraflow (Zinc (Zinc Citrate)).

For full term infants and children up to 5 years of age, 100 mcg zinc/kg/day (0.1 mL/kg/day) is recommended. For premature infants (birth weight less than 1500 g) up to 3 kg in body weight, 300 mcg zinc/kg/day (0.3 mL/kg/day) is suggested.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. See PRECAUTIONS.
