Summary

NSAIDs can blunt the diuretic and natriuretic response to loop diuretics such as ethacrynic acid. Both agents can also affect renal function, and the combination may increase the risk of acute kidney injury, particularly in volume-depleted patients.

What this interaction means in plain words

Ethacrynic acid and Sulindac 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.

Ethacrynic acid belongs to Cardiovascular; Sulindac belongs to Musculoskeletal.

Evidence level: Moderate

Why it happens

NSAID inhibition of renal prostaglandin synthesis reduces renal blood flow and sodium excretion, antagonizing loop diuretic effect.

What to do

Monitor blood pressure, fluid status, weight and serum creatinine. Increase the diuretic dose if response is diminished, or avoid the NSAID in heart failure or renal impairment.

What to ask your pharmacist

  • Should I take them at different times of day?
