Clemastine is a blocker of histamine H1 receptors and belongs to the group of benzhydryl esters. Has a selective inhibitory effect on histamine H1 receptors, reducing capillary permeability.

Absorption of clemastine from the gastrointestinal tract after oral administration is almost complete. The maximum concentration (Cmax) in blood plasma is reached after 2–4 hours.

The substance binds to plasma proteins up to 95%.

Excretion from plasma is two-phase, with a half-life (T 1/2) in the first phase - 3.6 ± 0.9 hours, in the second - 37 ± 16 hours.

Clemastine is extensively metabolized in the liver. It is excreted mainly through the kidneys with urine in the form of metabolites (45–65%), the active substance is present in unchanged form in trace amounts.
