Mechanism and action
Wellbutrin: Wellbutrin hemmt die Wiederaufnahme von Noradrenalin und Dopamin, mit deutlich schwächerer Wirkung auf Serotonin. Spironolactone: Spironolacton blockiert den Aldosteron-(Mineralokortikoid-)Rezeptor im distalen Tubulus kompetitiv und reduziert dadurch die Natriumrückresorption und die Kaliumausscheidung.
