Summary
Angiotensin receptor blockers lower aldosterone effects and reduce potassium excretion, so potassium supplements can cause hyperkalemia. Risk is higher with kidney disease, diabetes or older age.
What this interaction means in plain words
Irbesartan 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.
Irbesartan belongs to Cardiovascular; Potassium citrate-citric acid belongs to Gastrointestinal Tract.
Why it happens
Angiotensin II receptor blockade reduces aldosterone-mediated renal potassium excretion, adding to the potassium load.
What to do
Check serum potassium and creatinine before and soon after starting the combination, then periodically. Reduce or stop the potassium salt if potassium rises.
