Losartan

Hypertension: COZAAR is indicated for the treatment of hypertension.
Hypertensive Patients with Left Ventricular Hypertrophy: COZAAR is indicated to reduce the risk of stroke in patients with hypertension and left ventricular hypertrophy, but there is evidence that this benefit does not apply to Black patients (see Race under PRECAUTIONS).
Nephropathy in Type 2 Diabetic Patients: Indicated for the treatment of diabetic nephropathy with an elevated serum creatinine and proteinuria (urinary albumin to creatinine ratio ≥300 mg/g) in patients with type 2 diabetes and a history of hypertension. In this population, COZAAR reduces the rate of progression of nephropathy as measured by the occurrence of doubling the serum creatinine or end stage renal disease (need for dialysis or renal transplantation) or death.

Hypertension: The usual starting and maintenance dose is 50 mg once daily for most patients. The maximal antihypertensive effect is attained 3-6 weeks after initiation of therapy. Some patients may receive an additional benefit by increasing the dose to 100 mg once daily.
No initial dosage adjustment is necessary for elderly patients or for patients with renal impairment, including patients on dialysis. A lower dose should be considered for patients with a history of hepatic impairment.
Hypertensive Patients with Left Ventricular Hypertrophy: The usual starting dose is 50 mg of COZAAR once daily. A low dose of hydrochlorothiazide should be added and/or the dose of COZAAR should be increased to 100 mg once daily based on blood pressure response.
Renal Protection in Type 2 Diabetic Patients with Proteinuria and Hypertension: The usual starting dose is 50 mg once daily. The dose may be increased to 100 mg once daily based on blood pressure response. COZAAR may be administered with other antihypertensive agents.
