Pharmachologic effect

The antihistaminic agent is a pharmacologically active metabolite of terfenadine, stabilizes the membranes of mast cells, reduces the release of histamine and other biologically active substances from them. The antihistamine effect manifests itself 1 hour after ingestion, reaches a maximum after 6 hours and lasts for 24 hours. After 28 days of admission, there was no addiction. In the dose range of 10-130 mg, a dose-dependent effect is noted. Does not cause significant changes in the QT interval, does not have a sedative effect.

Pharmacokinetics

After oral intake is rapidly absorbed from the gastrointestinal tract, Cmax is determined after 1-3 hours. The average value of Cmax after taking 180 mg is approximately 494 ng / ml, and after taking 120 mg - 427 ng / ml. Binding to plasma proteins - 60-70%. T1 / 2 after repeated administration - 14.4 hours. It penetrates into breast milk. It is subject to partial (5% of the dose) extrahepatic metabolism. It is excreted mainly with bile (80%), 11% - in the unchanged form of the kidneys.
