Mechanism and action
Spironolactone: Spironolacton blockiert den Aldosteron-(Mineralokortikoid-)Rezeptor im distalen Tubulus kompetitiv und reduziert dadurch die Natriumrückresorption und die Kaliumausscheidung. Cialis Daily: Die PDE5-Hemmung durch Tadalafil verhindert den Abbau von zyklischem GMP in der penilen und vaskulären glatten Muskulatur.
When Spironolactone is preferred
