Mechanism and action
Plavix: Nach der Resorption wird Clopidogrel in der Leber in einen aktiven Metaboliten umgewandelt, der irreversibel an den ADP-P2Y12-Rezeptor auf Thrombozyten bindet. Spironolactone: Spironolacton blockiert den Aldosteron-(Mineralokortikoid-)Rezeptor im distalen Tubulus kompetitiv und reduziert dadurch die Natriumrückresorption und die Kaliumausscheidung.
