描述
NSAIDs reduce the natriuretic and diuretic efficacy of spironolactone, potentially leading to sodium retention and worsening edema or hypertension.
机制
Spironolactone's diuretic effect is partially prostaglandin-dependent; naproxen-mediated prostaglandin inhibition attenuates this mechanism and promotes sodium reabsorption.
临床意义
The interaction may be particularly significant in patients with heart failure or hepatic cirrhosis where diuretic response is already reduced.
处理措施
Avoid NSAIDs in patients taking spironolactone for heart failure or liver disease; monitor weight, edema, and renal function.
