Summary
NSAIDs can blunt the blood pressure lowering effect of ACE inhibitors and, together with them, can impair kidney function. The risk is highest in older adults, volume-depleted patients, and those with existing renal impairment or heart failure.
What this interaction means in plain words
Benazepril and Tolmetin can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Benazepril belongs to Cardiovascular; Tolmetin belongs to Musculoskeletal.
Why it happens
NSAID inhibition of renal prostaglandin synthesis reduces vasodilation of the afferent arteriole and sodium excretion, counteracting ACE inhibitor effects and lowering glomerular filtration under RAAS blockade.
What to do
Monitor blood pressure, serum creatinine and potassium after starting or changing the NSAID, and maintain hydration. Use the lowest effective NSAID dose for the shortest time, or choose paracetamol where suitable.
