Mechanism and action
Demadex: Torasemid blockiert den Na-K-2Cl-Cotransporter im dicken aufsteigenden Teil der Henle-Schleife und bewirkt eine starke Natriurese und Diurese. Spironolactone: Spironolacton blockiert den Aldosteron-(Mineralokortikoid-)Rezeptor im distalen Tubulus kompetitiv und reduziert dadurch die Natriumrückresorption und die Kaliumausscheidung.
