Pharmacological properties

Pharmacodynamics

Retinol acetate, vitamin A is an essential component for the normal functioning of the retina of the eye, which binds to the pigment opsin to form visual purpura rhodopsin, which provides visual adaptation in the dark. Vitamin A also participates in the processes of bone growth, embryonic development, regulation of division, differentiation of the epithelium (stimulates the reproduction of epithelial cells, rejuvenates the cell population, suppresses keratinization processes), and ensures normal reproductive function. Vitamin A is a cofactor in various biochemical processes.

Pharmacokinetics

Vitamin A is rapidly absorbed from the duodenum, jejunum and other organs of the gastrointestinal tract in the presence of bile acids, proteins, fats and pancreatic lipase. Normally, less than 5% binds to plasma proteins. With excessive consumption of food with vitamin A and overflow of the liver depot, the connection with lipoproteins can be up to 65%. Also, hyperlipoproteinemia may affect the increase in the amount of vitamin A associated with lipoproteins. Vitamin A, being released from the liver depot, forms a complex with retinol-binding protein, in the form of which it is in the blood. Small amounts cross the placenta and into breast milk. In the equivalent of a two-year need for an adult, it is deposited in the liver, in a small amount - in the kidneys and lungs. Mobilization from a depot requires zinc-containing substances.

Vitamin A is metabolized in the liver. It is excreted by the kidneys, and the non-absorbed part through the rectum.
