DESCRIPTION

Nervigenol Magnesio (Magnesium Aspartate) Sulfate Injection, USP is a sterile solution of Nervigenol Magnesio (Magnesium Aspartate) 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.

Nervigenol Magnesio (Magnesium Aspartate) 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

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

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

As plasma Nervigenol Magnesio (Magnesium Aspartate) 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 Nervigenol Magnesio (Magnesium Aspartate). Serum Nervigenol Magnesio (Magnesium Aspartate) concentrations in excess of 12 mEq/L may be fatal.

Nervigenol Magnesio (Magnesium Aspartate) 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 Nervigenol Magnesio (Magnesium Aspartate) 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. Nervigenol Magnesio (Magnesium Aspartate) is excreted solely by the kidneys at a rate proportional to the plasma concentration and glomerular filtration.

INDICATIONS AND USAGE

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

Nervigenol Magnesio (Magnesium Aspartate) 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 Nervigenol Magnesio (Magnesium Aspartate) 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. Nervigenol Magnesio (Magnesium Aspartate) sulfate should be used during pregnancy only if clearly needed. If Nervigenol Magnesio (Magnesium Aspartate) 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 Nervigenol Magnesio (Magnesium Aspartate) 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 Nervigenol Magnesio (Magnesium Aspartate) 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 Nervigenol Magnesio (Magnesium Aspartate), their dosage should be adjusted with caution because of additive CNS depressant effects of Nervigenol Magnesio (Magnesium Aspartate).

Because Nervigenol Magnesio (Magnesium Aspartate) 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 Nervigenol Magnesio (Magnesium Aspartate) 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 Nervigenol Magnesio (Magnesium Aspartate) should be given until they return. Serum Nervigenol Magnesio (Magnesium Aspartate) 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 Nervigenol Magnesio (Magnesium Aspartate) 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 Nervigenol Magnesio (Magnesium Aspartate) intoxication in eclampsia.

50% Nervigenol Magnesio (Magnesium Aspartate) 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

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

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

Cardiac Glycosides - Nervigenol Magnesio (Magnesium Aspartate) 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 Nervigenol Magnesio (Magnesium Aspartate) toxicity.

Pregnancy

Teratogenic Effects

Pregnancy Category D (See WARNINGS and PRECAUTIONS )

See WARNINGS and PRECAUTIONS .

Nervigenol Magnesio (Magnesium Aspartate) 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 Nervigenol Magnesio (Magnesium Aspartate) sulfate for more than 5 to 7 days.^1-10 Nervigenol Magnesio (Magnesium Aspartate) 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 Nervigenol Magnesio (Magnesium Aspartate) toxicity, including neuromuscular or respiratory depression (See OVERDOSAGE ).

Labor and Delivery

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

ADVERSE REACTIONS

The adverse effects of parenterally administered Nervigenol Magnesio (Magnesium Aspartate) usually are the result of Nervigenol Magnesio (Magnesium Aspartate) 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 Nervigenol Magnesio (Magnesium Aspartate) sulfate therapy for eclampsia has been reported.

OVERDOSAGE

Nervigenol Magnesio (Magnesium Aspartate) 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 Nervigenol Magnesio (Magnesium Aspartate) intoxication. In the event of overdosage, artificial ventilation must be provided until a calcium salt can be injected intravenously to antagonize the effects of Nervigenol Magnesio (Magnesium Aspartate).

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 Nervigenol Magnesio (Magnesium Aspartate) 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 Nervigenol Magnesio (Magnesium Aspartate) 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 Nervigenol Magnesio (Magnesium Aspartate) Deficiency

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

Nervigenol Magnesio (Magnesium Aspartate) sulfate in solution may result in a precipitate formation when mixed with solutions containing:

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. Nervigenol Magnesio (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. Nervigenol Magnesio (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 Nervigenol Magnesio prescribed?

For systemic use of Nervigenol Magnesio (Vitamin C) Kimia Farma: prevention and treatment of hypo- and avitaminosis of Nervigenol Magnesio (Vitamin C); providing increased need for Nervigenol Magnesio (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 Nervigenol Magnesio 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.

Nervigenol Magnesio (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.

Nervigenol Magnesio 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

Nervigenol Magnesio (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.

Nervigenol Magnesio (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.

Nervigenol Magnesio 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 Nervigenol Magnesio (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.

Nervigenol Magnesio (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.

Nervigenol Magnesio 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.
