ACE inhibitor
A combination of ACE inhibitor with other drugs may increase effects of these drugs, but also the risk of adverse effects. The commonly reported adverse effects of drug combination with ACE are acute renal failure, hypotension, and hyperkalemia. The drugs interacting with ACE inhibitor should be prescribed with caution. Special attention should be given to combinations of ACE inhibitor with other RAAS blockers, diuretics (especially potassium-sparing diuretics), NSAIDs, anticoagulants, cyclosporine, DPP-4 inhibitors, and potassium supplements.
