Pregnancy, lactation, hypersensitivity to piperidine derivatives.

A blocker of histamine H1 receptors from the group of piperidine derivatives. Provides antiallergic effect. It is characterized by a prolonged action (up to 48 hours), which is due to the formation of active metabolites. Unlike many blockers of histamine H1 receptors, ebastine has practically no m-anticholinergic activity, and also poorly penetrates the central nervous system and does not have a pronounced sedative effect.

Pharmacokinetics

Absorption is 90-95%. It is metabolized in the liver, turning into an active metabolite of karebastin. Fatty foods accelerate absorption (blood concentration increases 1.5 times) and presystemic metabolism (the formation of karebastin). Cmax after a single dose of 10 mg is achieved in 2.6-4 hours and is 80-100 ng / ml. Css is reached in 3-5 days and is 130-160 ng / ml. Plasma protein binding of ebastine and karebastin is 95%. T1 / 2 of karebastin - 15-19 hours, excreted by the kidneys - 60-70% in the form of conjugates. With renal failure, T1 / 2 increases to 23-26 hours, with liver failure - up to 27 hours.
