Summary
Candesartan reduces aldosterone-mediated potassium excretion, and potassium citrate adds a potassium load. Together they can cause clinically significant hyperkalemia, particularly in patients with renal impairment, diabetes or heart failure.
What this interaction means in plain words
Candesartan and Potassium citrate-citric acid 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.
Candesartan belongs to Cardiovascular; Potassium citrate-citric acid belongs to Gastrointestinal Tract.
Why it happens
Angiotensin receptor blockade lowers aldosterone-driven renal potassium excretion, adding to the exogenous potassium load.
What to do
Check serum potassium and renal function at baseline and within the first weeks of combined use, then periodically. Reduce or stop the potassium salt if potassium rises or renal function declines.
