Mechanism and action
Claritin: Loratadin blockiert selektiv periphere H1-Histaminrezeptoren und antagonisiert die Histaminwirkung bei allergischen Reaktionen. Lasix: Lasix wirkt in der Henle-Schleife der Niere, wo es den NKCC2-Cotransporter blockiert, der normalerweise Natrium, Chlorid und Kalium aus dem Harn in die Blutbahn rückresorbiert.
