Drug Interactions
Amlodipine: Increased metabolism with rifampin. Reduced hypotensive effect with calcium. Potentiates effects of thiazide diuretics and ACE inhibitors. Avoid combination with β-blockers in patients with markedly impaired left ventricular function.
Losartan: Concurrent use with NSAIDs may further worsen renal function. Cimetidine may increase the AUC of losartan by about 18%. Phenobarbital and other enzyme inducers may decrease levels of losartan and its active metabolite. Ketoconazole inhibits the conversion of losartan to its active metabolite. Concurrent use with potassium-sparing diuretics or potassium supplements or salt substitutes containing potassium may increase serum potassium levels. Reduces lithium excretion; monitor lithium levels if used together.
