This page compares them: when each is used, how the mechanisms and indications differ, and whether the question "Voltaren vs Spironolactone" makes sense to ask at all.
What is the relationship?

They belong to different therapeutic classes and are chosen for different indications.
When Voltaren is used

Mechanisms compared
Voltaren: Diclofenac hemmt reversibel die Cyclooxygenase-Enzyme COX-1 und COX-2, mit etwas stärkerer Selektivität für COX-2 als Ibuprofen und Naproxen. Spironolactone: Spironolacton blockiert kompetitiv den Mineralokortikoid-Rezeptor (Aldosteronrezeptor) im distalen Tubulus der Niere, vermindert die Natriumrückresorption und die Kaliumausscheidung.

Comparing Voltaren with Spironolactone makes sense when both are in the same clinical decision: the prescriber has weighed both for different but related conditions. If the question is between two options for the same need, the prescriber decides based on prior response, comorbidities and tolerance.
