5.1 Hypercalcemia

Patients with end stage renal disease may develop hypercalcemia when treated with Calcium Magnesium Formula (Calcium (Calcium Carbonate)), including Calcium Magnesium Formula (Calcium (Calcium Carbonate)) acetate. Avoid the use of Calcium Magnesium Formula (Calcium (Calcium Carbonate)) supplements, including Calcium Magnesium Formula (Calcium (Calcium Carbonate)) based nonprescription antacids, concurrently with Calcium Magnesium Formula (Calcium (Calcium Carbonate)) acetate.

An overdose of Calcium Magnesium Formula (Calcium (Calcium Carbonate)) acetate may lead to progressive hypercalcemia, which may require emergency measures. Therefore, early in the treatment phase during the dosage adjustment period, monitor serum Calcium Magnesium Formula (Calcium (Calcium Carbonate)) levels twice weekly. Should hypercalcemia develop, reduce the Calcium Magnesium Formula (Calcium (Calcium Carbonate)) acetate dosage, or discontinue the treatment, depending on the severity of hypercalcemia

More severe hypercalcemia (Ca >12 mg/dL) is associated with confusion, delirium, stupor and coma. Severe hypercalcemia can be treated by acute hemodialysis and discontinuing Calcium Magnesium Formula (Calcium (Calcium Carbonate)) acetate therapy.

Mild hypercalcemia (10.5 to 11.9 mg/dL) may be asymptomatic or manifest as constipation, anorexia, nausea, and vomiting. Mild hypercalcemia is usually controlled by reducing the Calcium Magnesium Formula (Calcium (Calcium Carbonate)) acetate dose or temporarily discontinuing therapy. Decreasing or discontinuing Vitamin D therapy is recommended as well.

Chronic hypercalcemia may lead to vascular calcification and other soft-tissue calcification. Radiographic evaluation of suspected anatomical regions may be helpful in early detection of soft tissue calcification. The long term effect of Calcium Magnesium Formula (Calcium (Calcium Carbonate)) acetate on the progression of vascular or soft tissue calcification has not been determined.

Hypercalcemia (>11 mg/dL) was reported in 16% of patients in a 3 month study of solid dose formulation of Calcium Magnesium Formula (Calcium (Calcium Carbonate)) acetate; all cases resolved upon lowering the dose or discontinuing treatment.

Maintain the serum calcium-phosphorus (Ca x P) product below 55 mg2/dL2.

7 DRUG INTERACTIONS

The drug interaction of Calcium Magnesium Formula ) acetate is characterized by the potential of Calcium Magnesium Formula (Calcium (Calcium Carbonate)) to bind to drugs with anionic functions (e.g., carboxyl, and hydroxyl groups). Calcium Magnesium Formula (Calcium (Calcium Carbonate)) acetate may decrease the bioavailability of tetracyclines or fluoroquinolones via this mechanism.

There are no empirical data on avoiding drug interactions between Calcium Magnesium Formula (Calcium (Calcium Carbonate)) acetate and most concomitant drugs. When administering an oral medication with Calcium Magnesium Formula (Calcium (Calcium Carbonate)) acetate where a reduction in the bioavailability of that medication would have a clinically significant effect on its safety or efficacy, administer the drug one hour before or three hours after Calcium Magnesium Formula (Calcium (Calcium Carbonate)) acetate. Monitor blood levels of the concomitant drugs that have a narrow therapeutic range. Patients taking anti-arrhythmic medications for the control of arrhythmias and anti-seizure medications for the control of seizure disorders were excluded from the clinical trials with all forms of Calcium Magnesium Formula (Calcium (Calcium Carbonate)) acetate.

- Calcium acetate may decrease the bioavailability of tetracyclines or fluoroquinolones. (7)

- When clinically significant drug interactions are expected, administer the drug at least one hour before or at least three hours after Calcium Magnesium Formula (Calcium (Calcium Carbonate)) acetate or consider monitoring blood levels of the drug. (7)

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

No carcinogenicity, mutagenicity, or fertility studies have been conducted with Calcium Magnesium Formula (Calcium (Calcium Carbonate)) acetate.

14 CLINICAL STUDIES

Effectiveness of Calcium Magnesium Formula (Calcium (Calcium Carbonate)) acetate in decreasing serum phosphorus has been demonstrated in two studies of the Calcium Magnesium Formula (Calcium (Calcium Carbonate)) acetate solid oral dosage form.

Ninety-one patients with end-stage renal disease who were undergoing hemodialysis and were hyperphosphatemic (serum phosphorus >5.5 mg/dL) following a 1 week phosphate binder washout period contributed efficacy data to an open-label, non-randomized study.

The patients received Calcium Magnesium Formula (Calcium (Calcium Carbonate)) acetate 667 mg tablets at each meal for a period of 12 weeks. The initial starting dose was 2 tablets per meal for 3 meals a day, and the dose was adjusted as necessary to control serum phosphorus levels. The average final dose after 12 weeks of treatment was 3.4 tablets per meal. Although there was a decrease in serum phosphorus, in the absence of a control group the true magnitude of effect is uncertain.

The data presented in Table 2 demonstrate the efficacy of Calcium Magnesium Formula (Calcium (Calcium Carbonate)) acetate in the treatment of hyperphosphatemia in end-stage renal disease patients. The effects on serum Calcium Magnesium Formula (Calcium (Calcium Carbonate)) levels are also presented.

Magnesium (Magnesium HVP Chelate):



Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) Sulfate

Injection, USP

Ansyr Plastic Syringe

Rx only

Hospira Logo

DESCRIPTION

Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) Sulfate Injection, USP is a sterile solution of Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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.

Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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

Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) (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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)). While there are large stores of Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) present intracellularly and in the bones of adults, these stores often are not mobilized sufficiently to maintain plasma levels. Parenteral Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) therapy repairs the plasma deficit and causes deficiency symptoms and signs to cease.

Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) prevents or controls convulsions by blocking neuromuscular transmission and decreasing the amount of acetylcholine liberated at the end plate by the motor nerve impulse. Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) levels range from 1.5 to 2.5 mEq/liter.

As plasma Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)). Serum Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) concentrations in excess of 12 mEq/L may be fatal.

Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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. Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) is excreted solely by the kidneys at a rate proportional to the plasma concentration and glomerular filtration.

INDICATIONS AND USAGE

Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) Sulfate Injection, USP is suitable for replacement therapy in Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) deficiency, especially in acute hypomagnesemia accompanied by signs of tetany similar to those observed in hypocalcemia. In such cases, the serum Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) (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), Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) sulfate may be added to the nutrient admixture to correct or prevent hypomagnesemia which can arise during the course of therapy.

Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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. Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) sulfate should be used during pregnancy only if clearly needed. If Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)), their dosage should be adjusted with caution because of additive CNS depressant effects of Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)).

Because Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) should be given until they return. Serum Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) intoxication in eclampsia.

50% Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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

Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) sulfate injection should not be given unless hypomagnesemia has been confirmed and the serum concentration of Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)), their dosage should be adjusted with caution because of additive CNS depressant effects of Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)). CNS depression and peripheral transmission defects produced by Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) may be antagonized by calcium.

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

Cardiac Glycosides - Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) toxicity.

Pregnancy

Teratogenic Effects

Pregnancy Category D (See WARNINGS and PRECAUTIONS )

See WARNINGS and PRECAUTIONS .

Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) sulfate for more than 5 to 7 days.1-10 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) toxicity, including neuromuscular or respiratory depression (See OVERDOSAGE ).

Labor and Delivery

Continuous administration of Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) sulfate is an unapproved treatment for preterm labor. The safety and efficacy of such use have not been established. The administration of Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) is distributed into milk during parenteral Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) should be monitored in such patients.

ADVERSE REACTIONS

The adverse effects of parenterally administered Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) usually are the result of Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) sulfate therapy for eclampsia has been reported.

OVERDOSAGE

Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) intoxication. In the event of overdosage, artificial ventilation must be provided until a calcium salt can be injected intravenously to antagonize the effects of Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)).

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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) Deficiency

In the treatment of mild Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) deficiency, the usual adult dose is 1 gram, equivalent to 8.12 mEq of Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) (2 mL of the 50% solution) injected intramuscularly every six hours for four doses (equivalent to a total of 32.5 mEq of Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) sulfate is 20 grams/48 hours and frequent serum Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) concentrations must be obtained. Continuous use of Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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, Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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

Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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 Calcium Magnesium Formula (Magnesium (Magnesium HVP Chelate)) 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.

Monitoring serum Calcium Magnesium Formula (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 Calcium Magnesium Formula (Magnesium (Magnesium Oxide)) should be given until they return. Serum Calcium Magnesium Formula (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 Calcium Magnesium Formula (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 Calcium Magnesium Formula (Magnesium (Magnesium Oxide)) intoxication in eclampsia.

50% Calcium Magnesium Formula (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

Calcium Magnesium Formula (Magnesium (Magnesium Oxide)) sulfate injection should not be given unless hypomagnesemia has been confirmed and the serum concentration of Calcium Magnesium Formula (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 Calcium Magnesium Formula (Magnesium (Magnesium Oxide)), their dosage should be adjusted with caution because of additive CNS depressant effects of Calcium Magnesium Formula (Magnesium (Magnesium Oxide)). CNS depression and peripheral transmission defects produced by Calcium Magnesium Formula (Magnesium (Magnesium Oxide)) may be antagonized by calcium.

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

Cardiac Glycosides - Calcium Magnesium Formula (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 Calcium Magnesium Formula (Magnesium (Magnesium Oxide)) toxicity.

Pregnancy

Teratogenic Effects

Pregnancy Category D (See WARNINGS and PRECAUTIONS )

See WARNINGS and PRECAUTIONS .

Calcium Magnesium Formula (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 Calcium Magnesium Formula (Magnesium (Magnesium Oxide)) sulfate for more than 5 to 7 days.1-10 Calcium Magnesium Formula (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 Calcium Magnesium Formula (Magnesium (Magnesium Oxide)) toxicity, including neuromuscular or respiratory depression (See OVERDOSAGE ).

Labor and Delivery

Continuous administration of Calcium Magnesium Formula (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 Calcium Magnesium Formula (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 Calcium Magnesium Formula (Magnesium (Magnesium Oxide)) is distributed into milk during parenteral Calcium Magnesium Formula (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 Calcium Magnesium Formula (Magnesium (Magnesium Oxide)) should be monitored in such patients.

ADVERSE REACTIONS

The adverse effects of parenterally administered Calcium Magnesium Formula (Magnesium (Magnesium Oxide)) usually are the result of Calcium Magnesium Formula (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 Calcium Magnesium Formula (Magnesium (Magnesium Oxide)) sulfate therapy for eclampsia has been reported.

OVERDOSAGE

Calcium Magnesium Formula (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 Calcium Magnesium Formula (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 Calcium Magnesium Formula (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 Calcium Magnesium Formula (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 Calcium Magnesium Formula (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 Calcium Magnesium Formula (Magnesium (Magnesium Oxide)) Deficiency

In the treatment of mild Calcium Magnesium Formula (Magnesium (Magnesium Oxide)) deficiency, the usual adult dose is 1 gram, equivalent to 8.12 mEq of Calcium Magnesium Formula (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 Calcium Magnesium Formula (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 Calcium Magnesium Formula (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 Calcium Magnesium Formula (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 Calcium Magnesium Formula (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 Calcium Magnesium Formula (Magnesium (Magnesium Oxide)) sulfate is 20 grams/48 hours and frequent serum Calcium Magnesium Formula (Magnesium (Magnesium Oxide)) concentrations must be obtained. Continuous use of Calcium Magnesium Formula (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 Calcium Magnesium Formula (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, Calcium Magnesium Formula (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

Calcium Magnesium Formula (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 Calcium Magnesium Formula (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.

Potassium (Potassium Citrate):



Calcium Magnesium Formula (Potassium (Potassium Citrate)) CHLORIDE EXTENDED RELEASE TABLETS USP 20 mEq K

Rx Only

DESCRIPTION

The Calcium Magnesium Formula (Potassium (Potassium Citrate)) Chloride Extended Release Tablets USP, 20 mEq product is an immediately dispersing extended release oral dosage form of Calcium Magnesium Formula (Potassium (Potassium Citrate)) chloride containing 1500 mg of microencapsulated Calcium Magnesium Formula (Potassium (Potassium Citrate)) chloride, USP equivalent to 20 mEq of Calcium Magnesium Formula (Potassium (Potassium Citrate)) in a tablet.

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

Calcium Magnesium Formula (Potassium (Potassium Citrate)) Chloride Extended Release Tablets USP, 20 mEq is an electrolyte replenisher. The chemical name of the active ingredient is Calcium Magnesium Formula (Potassium (Potassium Citrate)) chloride, and the structural formula is KCl. Calcium Magnesium Formula (Potassium (Potassium Citrate)) 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.

Calcium Magnesium Formula (Potassium (Potassium Citrate)) Chloride Extended Release Tablets USP, 20 mEq is a tablet formulation (not enteric coated or wax matrix) containing individually microencapsulated Calcium Magnesium Formula (Potassium (Potassium Citrate)) chloride crystals which disperse upon tablet disintegration. In simulated gastric fluid at 37°C and in the absence of outside agitation, Calcium Magnesium Formula (Potassium (Potassium Citrate)) 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 Calcium Magnesium Formula (Potassium (Potassium Citrate)) chloride.

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

CLINICAL PHARMACOLOGY

The Calcium Magnesium Formula (Potassium (Potassium Citrate)) ion is the principal intracellular cation of most body tissues. Calcium Magnesium Formula (Potassium (Potassium Citrate)) 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 Calcium Magnesium Formula (Potassium (Potassium Citrate)) 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.

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

Calcium Magnesium Formula (Potassium (Potassium Citrate)) depletion will occur whenever the rate of Calcium Magnesium Formula (Potassium (Potassium Citrate)) loss through renal excretion and/or loss from the gastrointestinal tract exceeds the rate of Calcium Magnesium Formula (Potassium (Potassium Citrate)) intake. Such depletion usually develops as a consequence of therapy with diuretics, primary or secondary hyperaldosteronism, diabetic ketoacidosis, or inadequate replacement of Calcium Magnesium Formula (Potassium (Potassium Citrate)) in patients on prolonged parenteral nutrition. Depletion can develop rapidly with severe diarrhea, especially if associated with vomiting. Calcium Magnesium Formula (Potassium (Potassium Citrate)) depletion due to these causes is usually accompanied by a concomitant loss of chloride and is manifested by hypokalemia and metabolic alkalosis. Calcium Magnesium Formula (Potassium (Potassium Citrate)) 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 Calcium Magnesium Formula (Potassium (Potassium Citrate)) 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 Calcium Magnesium Formula (Potassium (Potassium Citrate)) in the form of high Calcium Magnesium Formula (Potassium (Potassium Citrate)) food or Calcium Magnesium Formula (Potassium (Potassium Citrate)) chloride may be able to restore normal Calcium Magnesium Formula (Potassium (Potassium Citrate)) levels.

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

INDICATIONS AND USAGE

BECAUSE OF REPORTS OF INTESTINAL AND GASTRIC ULCERATION AND BLEEDING WITH CONTROLLED-RELEASE Calcium Magnesium Formula (Potassium (Potassium Citrate)) CHLORIDE PREPARATIONS, THESE DRUGS SHOULD BE RESERVED FOR THOSE PATIENTS WHO CANNOT TOLERATE OR REFUSE TO TAKE LIQUID OR EFFERVESCENT Calcium Magnesium Formula (Potassium (Potassium Citrate)) 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 Calcium Magnesium Formula (Potassium (Potassium Citrate)) 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 Calcium Magnesium Formula (Potassium (Potassium Citrate)) 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 Calcium Magnesium Formula (Potassium (Potassium Citrate)) salts may be indicated.

CONTRAINDICATIONS

Calcium Magnesium Formula (Potassium (Potassium Citrate)) supplements are contraindicated in patients with hyperkalemia since a further increase in serum Calcium Magnesium Formula (Potassium (Potassium Citrate)) 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 Calcium Magnesium Formula (Potassium (Potassium Citrate)) chloride have produced esophageal ulceration in certain cardiac patients with esophageal compression due to enlarged left atrium. Calcium Magnesium Formula (Potassium (Potassium Citrate)) supplementation, when indicated in such patients, should be given as a liquid preparation or as an aqueous (water) suspension of Calcium Magnesium Formula (Potassium (Potassium Citrate)) Chloride (see PRECAUTIONS: Information for Patients , and DOSAGE AND ADMINISTRATION sections).

All solid oral dosage forms of Calcium Magnesium Formula (Potassium (Potassium Citrate)) 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 Calcium Magnesium Formula (Potassium (Potassium Citrate)), the administration of Calcium Magnesium Formula (Potassium (Potassium Citrate)) salts can produce hyperkalemia and cardiac arrest. This occurs most commonly in patients given Calcium Magnesium Formula (Potassium (Potassium Citrate)) by the intravenous route but may also occur in patients given Calcium Magnesium Formula (Potassium (Potassium Citrate)) orally. Potentially fatal hyperkalemia can develop rapidly and be asymptomatic. The use of Calcium Magnesium Formula (Potassium (Potassium Citrate)) salts in patients with chronic renal disease, or any other condition which impairs Calcium Magnesium Formula (Potassium (Potassium Citrate)) excretion, requires particularly careful monitoring of the serum Calcium Magnesium Formula (Potassium (Potassium Citrate)) concentration and appropriate dosage adjustment.

Interaction with Potassium-Sparing Diuretics

Hypokalemia should not be treated by the concomitant administration of Calcium Magnesium Formula (Potassium (Potassium Citrate)) 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 Calcium Magnesium Formula (Potassium (Potassium Citrate)) retention by inhibiting aldosterone production. Calcium Magnesium Formula (Potassium (Potassium Citrate)) supplements should be given to patients receiving ACE inhibitors only with close monitoring.

Gastrointestinal Lesions

Solid oral dosage forms of Calcium Magnesium Formula (Potassium (Potassium Citrate)) chloride can produce ulcerative and/or stenotic lesions of the gastrointestinal tract. Based on spontaneous adverse reaction reports, enteric-coated preparations of Calcium Magnesium Formula (Potassium (Potassium Citrate)) 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. Calcium Magnesium Formula (Potassium (Potassium Citrate)) Chloride Extended Release Tablets USP, 20 mEq is a tablet formulated to provide a controlled rate of release of microencapsulated Calcium Magnesium Formula (Potassium (Potassium Citrate)) chloride and thus to minimize the possibility of a high local concentration of Calcium Magnesium Formula (Potassium (Potassium Citrate)) 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 Calcium Magnesium Formula (Potassium (Potassium Citrate)) 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 Calcium Magnesium Formula (Potassium (Potassium Citrate)) 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 Calcium Magnesium Formula (Potassium (Potassium Citrate)) 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. Calcium Magnesium Formula (Potassium (Potassium Citrate)) 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 Calcium Magnesium Formula (Potassium (Potassium Citrate)) salt such as Calcium Magnesium Formula (Potassium (Potassium Citrate)) bicarbonate, Calcium Magnesium Formula (Potassium (Potassium Citrate)) citrate, Calcium Magnesium Formula (Potassium (Potassium Citrate)) acetate, or Calcium Magnesium Formula (Potassium (Potassium Citrate)) gluconate.

PRECAUTIONS

General

The diagnosis of Calcium Magnesium Formula ) depletion is ordinarily made by demonstrating hypokalemia in a patient with a clinical history suggesting some cause for Calcium Magnesium Formula (Potassium (Potassium Citrate)) depletion. In interpreting the serum Calcium Magnesium Formula (Potassium (Potassium Citrate)) level, the physician should bear in mind that acute alkalosis per se can produce hypokalemia in the absence of a deficit in total body Calcium Magnesium Formula (Potassium (Potassium Citrate)) while acute acidosis per se can increase the serum Calcium Magnesium Formula (Potassium (Potassium Citrate)) concentration into the normal range even in the presence of a reduced total body Calcium Magnesium Formula (Potassium (Potassium Citrate)). The treatment of Calcium Magnesium Formula (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 Calcium Magnesium Formula (Potassium (Potassium Citrate)) Chloride that is not taken immediately should be discarded. The use of other liquids for suspending Calcium Magnesium Formula (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 Calcium Magnesium Formula ) 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. Calcium Magnesium Formula ) is a normal dietary constituent.

Pregnancy Category C

Animal reproduction studies have not been conducted with Calcium Magnesium Formula (Potassium (Potassium Citrate)) Chloride Extended Release Tablets USP, 20 mEq. It is unlikely that Calcium Magnesium Formula (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 Calcium Magnesium Formula ) ion content of human milk is about 13 mEq per liter. Since oral Calcium Magnesium Formula (Potassium (Potassium Citrate)) becomes part of the body Calcium Magnesium Formula (Potassium (Potassium Citrate)) pool, so long as body Calcium Magnesium Formula (Potassium (Potassium Citrate)) is not excessive, the contribution of Calcium Magnesium Formula (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 Calcium Magnesium Formula (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 Calcium Magnesium Formula (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 Calcium Magnesium Formula (Potassium (Potassium Citrate)) salts to persons with normal excretory mechanisms for Calcium Magnesium Formula (Potassium (Potassium Citrate)) rarely causes serious hyperkalemia. However, if excretory mechanisms are impaired or if Calcium Magnesium Formula (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 Calcium Magnesium Formula (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.
