Mechanism and action
Spironolactone: Spironolacton blockiert den Aldosteron-(Mineralokortikoid-)Rezeptor im distalen Tubulus kompetitiv und reduziert dadurch die Natriumrückresorption und die Kaliumausscheidung. Stendra: Avanafil hemmt selektiv die Phosphodiesterase Typ 5 (PDE5) im Schwellkörper, erhöht die cGMP-Konzentration und verstärkt die durch Stickstoffmonoxid vermittelte Vasodilatation als Reaktion auf sexuelle Stimulation.
