Key differences
Spironolactone belongs to Diuretika while Zoloft belongs to Antidepressiva. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Spironolactone: Spironolacton blockiert den Aldosteron-(Mineralokortikoid-)Rezeptor im distalen Tubulus kompetitiv und reduziert dadurch die Natriumrückresorption und die Kaliumausscheidung. Zoloft: Sertralin wirkt durch selektive Blockade des Serotonintransporters und verhindert so die Wiederaufnahme von Serotonin aus dem synaptischen Spalt, wodurch die synaptische Serotoninkonzentration erhöht wird.
When Spironolactone is preferred
