When Plavix is used

Spironolacton ist zugelassen bei Herzinsuffizienz mit reduzierter Ejektionsfraktion, primärem Hyperaldosteronismus, therapieresistenter Hypertonie, Ödemen bei Leberzirrhose oder nephrotischem Syndrom und bestimmten Kaliumverlustzuständen.
Mechanisms compared
Plavix: Nach der Resorption wird Clopidogrel in der Leber in einen aktiven Metaboliten umgewandelt, der irreversibel an den ADP-P2Y12-Rezeptor auf Thrombozyten bindet. Spironolactone: Spironolacton blockiert kompetitiv den Mineralokortikoid-Rezeptor (Aldosteronrezeptor) im distalen Tubulus der Niere, vermindert die Natriumrückresorption und die Kaliumausscheidung.
When the comparison makes sense
Comparing Plavix 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.
