Pharmacological properties

Pharmacokinetics

Ascorbic acid is rapidly absorbed in the duodenum and jejunum. Within 30 minutes after administration, the content of ascorbic acid in the blood increases markedly, its capture by tissues begins, while

it first turns into dehydroascorbic acid, which has the ability to penetrate cell membranes without energy costs and quickly recover in the cell. Ascorbic acid in tissues is found almost exclusively intracellularly, it is determined in three forms - ascorbic, dehydroascorbic acids and ascorbigen (bound ascorbic acid). The distribution between the organs is uneven: there is a lot of it in the endocrine glands, especially in the adrenal glands, less in the brain, kidneys, liver, in the heart and skeletal muscles. Ascorbic acid is partially metabolized and excreted up to 90% by the kidneys in the form of oxalate, partially in free form.

Pharmacodynamics

Ascorbic acid, which includes a dienol group, has pronounced reducing properties. This is related to its participation in redox processes, regulation of carbohydrate metabolism, blood coagulation, biosynthesis of steroid hormones, tissue regeneration, synthesis of collagen and procollagen, normalization of capillary permeability. Lack of ascorbic acid in food, which is not synthesized in the body, contributes to the development of avitaminosis. or hypovitaminosis C.
