Key differences
Crestor belongs to Herz-Kreislauf-Medikamente while Spironolactone belongs to Diuretika. 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
Crestor: Rosuvastatin hemmt kompetitiv die HMG-CoA-Reduktase, das geschwindigkeitsbestimmende Enzym der hepatischen Cholesterinsynthese. Spironolactone: Spironolacton blockiert den Aldosteron-(Mineralokortikoid-)Rezeptor im distalen Tubulus kompetitiv und reduziert dadurch die Natriumrückresorption und die Kaliumausscheidung.
When Crestor is preferred
Crestor ist bei Erwachsenen zur Behandlung der primären Hypercholesterinämie und gemischten Dyslipidämie, zur Prävention kardiovaskulärer Ereignisse bei Patienten mit erhöhtem Risiko und zur Sekundärprävention zugelassen.
When Spironolactone is preferred
