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