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. Chlorthalidone: Chlortalidon hemmt den Natrium-Chlorid-Symporter im distalen Konvolut der Niere, reduziert die Natriumrückresorption und führt zu einer mäßigen Diurese.
