Pharmacological action

Ferrum Lek - antianemic drug.

The molecular weight of the complex is so great - about 50 kDa - that its diffusion through the gastrointestinal mucosa is 40 times slower than diffusion of ferrous iron. The complex is stable and does not release iron ions under physiological conditions. The iron of the multinuclear active zones of the complex is bound into a structure similar to that of the natural compound of iron, ferritin. Due to this similarity, the iron of this complex is absorbed only by active absorption. Iron binding proteins located on the surface of the intestinal epithelium, absorb iron (III) from the complex through competitive exchange of ligands. Absorbed iron is mainly deposited in the liver, where it binds to ferritin. Later in the bone marrow, it is included in hemoglobin.

The iron (III) complex polymaltose hydroxide does not have the prooxidant properties inherent in iron (II) salts.

Pharmacokinetics

Studies using the double isotope method (55Fe and 59Fe) showed that iron absorption, as measured by hemoglobin in red blood cells, is inversely proportional to the dose taken (the higher the dose, the lower the absorption). There is a statistically negative correlation between the degree of iron deficiency and the amount of iron absorbed (the higher the iron deficiency, the better the absorption). Iron is most absorbed in the duodenum and jejunum.

The remaining (non-absorbed) iron is excreted in the feces. Its excretion with exfoliating cells of the gastrointestinal tract and skin epithelium, as well as with sweat, bile and urine, is approximately 1 mg of iron per day. In women, during menstruation, an additional loss of iron occurs, which must be taken into account.

Indications

For oral use:

treatment of latent iron deficiency

treatment of iron deficiency anemia

prevention of iron deficiency during pregnancy and lactation.

Contraindications

excess iron in the body (e.g. hemochromatosis)

non-iron deficiency anemia (e.g. hemolytic anemia, megaloblastic anemia caused by cyanocobalamin deficiency)

hypersensitivity to pre Arata.

Use in children

Use is possible according to indications and in doses taking into account the age of the patient. For children under 12 years of age, in connection with the need to prescribe the drug in low doses, it is preferable to use in the form of a syrup.

Use during pregnancy and lactation

In controlled trials with the use of the drug in the II and III trimesters of pregnancy, there was no negative effect on the mother or fetus. There were no harmful effects on the fetus when using the drug in the first trimester of pregnancy.

Special instructions

In cases of anemia caused by an infectious or malignant disease, iron accumulates in the reticuloendothelial system, from which it is mobilized and utilized only after the underlying disease has been cured.

When using the Ferrum LekВ® preparation, the stool may become dark in color, which does not have any clinical significance. Ferrum LekВ® does not affect the results of the occult blood test (selective for hemoglobin), so it is not required to suspend iron therapy.

Note for patients with diabetes: 1 chewable tablet Ferrum LekВ® contains 0.04 bread units (XE).

Note for patients with phenylketonuria: Ferrum LekВ® contains aspartame (E951), a source of phenylalanine, in an amount equivalent to 1.5 mg per tablet.

Influence on the ability to drive vehicles, mechanisms

Ferrum LekВ® does not affect the ability to drive a car and control mechanisms that require increased concentration of attention.
