Key differences
Voltaren belongs to Schmerzmedikamente while Lasix 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
Voltaren: Diclofenac hemmt reversibel die Cyclooxygenase-Enzyme COX-1 und COX-2, mit etwas stärkerer Selektivität für COX-2 als Ibuprofen und Naproxen. Lasix: Lasix wirkt in der Henle-Schleife der Niere, wo es den NKCC2-Cotransporter blockiert, der normalerweise Natrium, Chlorid und Kalium aus dem Harn in die Blutbahn rückresorbiert.
