Pharmacological properties
Pharmacodynamics.
Magnesium is an intracellular cation that reduces neuronal excitability and inhibits neuromuscular transmission, and is also involved in many enzymatic reactions. Magnesium is an important component of body tissues: skeletal bones contain half of the total amount of magnesium in the body.
A serum magnesium concentration of 12 to 17 mg/L (1–1.4 mEq/L, or 0.5–0.7 mmol/L) indicates moderate magnesium deficiency; below 12 mg/L (1 mEq/L, or 0.5 mmol/L) indicates severe magnesium deficiency.
Magnesium deficiency can be:
– primary, due to metabolic pathology (chronic congenital hypomagnesemia);
– secondary, due to:
insufficient intake of magnesium with food (unhealthy diet, chronic alcohol abuse, exclusively parenteral nutrition);
impaired absorption of magnesium in the gastrointestinal tract (chronic diarrhea, gastrointestinal fistulas, hypoparathyroidism);
excessive loss of magnesium due to renal excretion (tubular disorders, severe polyuria, diuretic abuse, chronic pyelonephritis, primary hyperaldosteronism, cisplatin treatment).
Pharmacokinetics.
The absorption of magnesium salts in the gastrointestinal tract involves, among other mechanisms, a passive mechanism for which the solubility of the salt is a determining factor.
Absorption of magnesium salts in the gastrointestinal tract does not exceed 50%. Magnesium is excreted mainly in the urine.
Indication
Treatment of confirmed magnesium deficiency in the body, both isolated and associated with other deficiency conditions.
Contraindication
Hypersensitivity to any component of the drug. Severe renal failure with creatinine clearance less than 30 ml/min. Phenylketonuria. Hypermagnesemia, vitamin B6 hypervitaminosis, myasthenia gravis. Atrioventricular block, severe arterial hypotension. Simultaneous use with levodopa (see section "Interaction with other medicinal products and other types of interactions"). Diarrhea. Fructose intolerance, glucose or galactose malabsorption syndrome, sucrase-isomaltase deficiency (due to the content of sucrose in the drug).
Interaction with other medicinal products and other types of interactions
Contraindicated combinations.
Concomitant use with levodopa should be avoided, as the effect of levodopa is inhibited when its use is not accompanied by peripheral dopa decarboxylase inhibitors. The use of pyridoxine in any quantities is not indicated if levodopa is not accompanied by dopa decarboxylase inhibitors.
Not recommended combinations.
Do not use with drugs containing phosphate or calcium salts, as they inhibit the absorption of magnesium from the intestines.
Combinations requiring caution when used.
Use with caution with oral tetracyclines, as magnesium reduces the absorption of tetracyclines from the stomach and intestines. When used simultaneously with oral tetracyclines, the administration of Magne-B6Ò should be delayed by at least 3 hours.
Magnesium preparations weaken the effect of oral anticoagulants and reduce iron absorption.
Diuretics increase the excretion of magnesium in the urine.
The use of hydralazine, isoniazid, penicillamine, and oral contraceptives increases the need for vitamin B6.
Application features
Patients with severe magnesium deficiency should be started on intravenous magnesium. This is also indicated for patients with malabsorption.
In patients with concomitant calcium deficiency, it is recommended in most cases to first correct the magnesium deficiency before prescribing calcium.
As this medicinal product contains sucrose, it is contraindicated in patients with fructose intolerance, glucose-galactose malabsorption syndrome or sucrase-isomaltase insufficiency.
Information for diabetics: film-coated tablets contain sucrose as an excipient.
Pyridoxine abuse can lead to sensory neuropathy when taken in high doses (>200 mg/day) over a long period of time (i.e., several months or years). Symptoms include numbness, sensory disturbances, tremors, and gradually progressive sensory ataxia (problems with coordination). This effect is usually reversible and disappears after discontinuation of the drug.
THIS MEDICINE IS INTENDED FOR USE ONLY BY ADULTS AND CHILDREN 6 YEARS OLD AND OVER.
Appropriate dosage forms are available for use in children under 6 years of age.
Patients with moderate renal insufficiency should take precautions to prevent any risks associated with hypermagnesemia.
Use during pregnancy or breastfeeding
Pregnancy: Limited data from clinical studies in animals have not revealed fetotoxic or embryotoxic effects of the drug. Therefore, the use of magnesium during pregnancy is possible only if necessary and after consultation with a doctor.
Breastfeeding. Each of the active ingredients of the drug separately (both magnesium and vitamin B6) is not contraindicated during this period. Given the limited evidence on the use of the maximum recommended daily dose of vitamin B6 during breastfeeding, it is recommended to prescribe no more than 20 mg/day of vitamin B6.
Ability to influence reaction speed when driving vehicles or other mechanisms
The drug Magne-B6, film-coated tablets, has no or negligible effect on the reaction rate when driving vehicles or using other mechanisms.
Method of administration and doses
The tablets should be swallowed whole with 1 glass of water.
Adults: 6–8 tablets per day, dividing the total dose into 2 or 3 doses during meals.
Children aged 6 years and over (with a body weight of more than 20 kg): 10–30 mg/kg body weight per day (i.e. 0.4–1.2 mmol/kg body weight per day), which corresponds to taking 4–6 tablets per day, dividing the total dose into 2 or 3 doses during meals.
The drug should be discontinued as soon as the magnesium level in the blood reaches normal.
Children. The drug is used in children aged 6 years and older. Appropriate dosage forms are available for use in children under 6 years of age.
Overdose
Magnesium-related
Overdose of oral magnesium usually does not lead to toxic reactions in patients with normal renal function. However, magnesium intoxication may develop in patients with renal insufficiency.
Toxic effects depend on magnesium levels in the blood and are manifested by the following signs:
a sharp decrease in blood pressure;
nausea, vomiting;
central nervous system depression, impaired reflex functions;
pathological changes on the ECG;
development of respiratory depression, coma, cardiac arrest and respiratory paralysis;
anury.
Treatment of overdose: rehydration, forced diuresis. Patients with renal failure require hemodialysis or peritoneal dialysis.
Related to pyridoxine
Sensory axonal neuropathy is a major effect that can occur with prolonged and/or long-term use of high doses of pyridoxine (several months or years).
Signs and symptoms
In particular, paraesthesia, dysesthesia, hypoesthesia, sensory deficits, pain in the extremities, involuntary muscle contractions, burning, balance disorders, gait disturbances, tremor of the hands and feet and progressive sensory ataxia (difficulty in coordinating movements) have been reported.
Treatment
Neurological symptoms gradually disappear after discontinuation of treatment.
