Summary

Loop diuretic-induced volume depletion combined with ACE inhibition can cause marked first-dose hypotension and acute renal impairment. The risk is highest in sodium- or volume-depleted patients and at initiation.

What this interaction means in plain words

Ethacrynic acid and Lisinopril 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; Lisinopril belongs to Cardiovascular.

Evidence level: High

Why it happens

Diuretic volume depletion activates the renin-angiotensin system, and ACE inhibition removes this compensation, causing hypotension and reduced glomerular filtration.

What to do

Consider lowering or temporarily holding the diuretic before starting lisinopril, and start with a low dose. Check blood pressure, creatinine and potassium within the first weeks.
