Pharmacological properties.

Pharmacodynamics.

Boric acid has antiseptic and fungistatic activity, as well as an astringent effect. It coagulates proteins (including enzymatic proteins) of microbial cells and disrupts the permeability of the cell membrane. A 5% aqueous solution inhibits phagocytosis, while 2–4% solutions inhibit the growth and development of bacteria. It has a weak irritant effect on granulation tissues.

Pharmacokinetics.

It is absorbed through the affected area of skin and through the mucous membranes of the gastrointestinal tract (in case of accidental ingestion).

The drug penetrates well through the skin and mucous membranes; it is poorly excreted from the body and may accumulate in internal organs and tissues.
