Summary
Ethacrynic acid is a loop diuretic that increases urinary potassium loss, whereas potassium citrate supplies potassium. The combination is often used intentionally to prevent hypokalemia, so the effects mostly offset one another.

Ethacrynic acid belongs to Cardiovascular; Potassium citrate belongs to Gastrointestinal Tract.
Why it happens

What to do
Monitor serum potassium and renal function periodically and titrate the potassium dose to the target level.
