Pharmacological properties

Vitamins of the group (b1, b2, b6, pantothenic acid and nicotinamide) are involved in the metabolism of carbohydrates, proteins and fats, they are also important for the functioning of the nervous system. Vitamin A is necessary for the development of epithelial cells and the synthesis of visual pigment. Vitamin D regulates the absorption of calcium and promotes proper mineralization of bones and teeth. Vitamin C controls the absorption of iron and takes part in redox processes in the body. Vitamin E, a physiological antioxidant, protects cell membranes from damage and preserves their functionality.

Minerals and oligoelements are very important for the body. They are constituent tissues or activators and constituents of enzymes and hormones. Calcium and phosphorus, which are part of the drug Duovit, are the main mineral components of bone tissue and teeth. Calcium ions activate many enzymes, are involved in the regulation of cardiac muscle tone, transmission of nerve impulses and regulate the permeability of cell membranes. Iron and copper along with B vitamins are necessary for erythropoiesis. Magnesium, manganese, zinc and molybdenum are part of most enzymes that catalyze the most important biochemical reactions in the body.

Water-soluble vitamins (B vitamins, vitamin C and biotin) are very well absorbed within daily requirements. Amounts that exceed absorption by tissues are excreted in the urine, in some cases also with feces.

After oral administration, the fat-soluble vitamins A and D are well absorbed in the small intestine in the presence of fats. Vitamin E absorption is relatively low (25–85% of the dose). These vitamins accumulate in large quantities in the liver and are therefore more toxic than water-soluble vitamins.

special instructions

Duovit is taken after meals, otherwise unpleasant sensations in the stomach may occur.

Patients with diabetes can use Duovit, but they should be aware that the daily dose contains 1.6 g of sugar. Each coated tablet contains 0.8 g of sugar.

Women taking high-dose retinol (10,000 IU) can be scheduled for pregnancy no sooner than after 6–12 months. This is due to the fact that during this period there is a risk of abnormal development of the fetus under the influence of a high content of vitamin A in the body. It is possible to stain urine in yellow, which is completely harmless and is explained by the presence of riboflavin in the preparation.
