Summary

Naproxen can weaken the antihypertensive effect of ramipril. The combination may also reduce renal function and cause acute kidney injury, mainly in older, dehydrated or renally impaired patients.

What this interaction means in plain words

Naproxen and Ramipril can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Naproxen belongs to Musculoskeletal; Ramipril belongs to Cardiovascular.

Evidence level: High

Why it happens

NSAID inhibition of vasodilatory renal prostaglandins opposes ACE inhibitor effects and, with reduced angiotensin II-mediated efferent tone, lowers glomerular filtration.

What to do

Prefer a non-NSAID analgesic. If co-use is necessary, ensure adequate hydration and monitor blood pressure, serum creatinine and potassium, particularly after starting or changing doses.

What to ask your pharmacist
