Summary
Heparins, including low molecular weight heparins like dalteparin, can suppress aldosterone secretion and cause hyperkalemia. With olmesartan, which also raises potassium, the risk is increased, particularly in renal impairment or diabetes.
What this interaction means in plain words
Amlodipine-olmesartan and Dalteparin 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.
Amlodipine-olmesartan belongs to Cardiovascular; Dalteparin belongs to Cardiovascular.
Why it happens
Heparin-induced inhibition of adrenal aldosterone synthesis adds to angiotensin receptor blockade, reducing potassium excretion.
What to do
Monitor serum potassium and renal function, particularly with prolonged dalteparin use or in high-risk patients.
