Summary
ACE inhibitors such as quinapril lower aldosterone and decrease potassium excretion. Adding potassium salts can cause clinically significant hyperkalemia, particularly in renal impairment, heart failure or diabetes.
What this interaction means in plain words
Potassium citrate-citric acid and Quinapril 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.
Why it happens
ACE inhibition reduces aldosterone-mediated potassium excretion, which adds to the exogenous potassium.
What to do
Check potassium and creatinine at baseline and within the first weeks, then periodically. Reduce or stop the potassium supplement if hyperkalemia develops.
