Quick Summary

Losartan potassium and hydrochlorothiazide is a combination medication used to treat high blood pressure and reduce the risk of stroke in patients with hypertension and left ventricular hypertrophy. The medication works by blocking the action of angiotensin II, a potent vasoconstrictor, and increasing the excretion of sodium and chloride in the urine. The usual starting dose is 50/12.5 mg once daily, with a maximum dose of 100/25 mg. Important safety information includes the risk of fetal harm, hyperkalemia, and hypotension. Contraindications include hypersensitivity to any component of the medication, anuria, and coadministration with aliskiren in patients with diabetes.
