Dosage and Administration

AVAPRO may be administered with other antihypertensive agents and with or without food.

Hypertension

The recommended initial dose of AVAPRO (irbesartan) is 150 mg once daily. Patients requiring further reduction in blood pressure should be titrated to 300 mg once daily.

A low dose of a diureticmay be added, if blood pressure is not controlled by AVAPRO alone. Hydrochlorothiazide has been shown to have an additive effect (seeCLINICAL PHARMACOLOGY: Clinical Studies). Patients not adequately treated by the maximum dose of 300 mg once daily are unlikely to derive additional benefit from a higher dose or twice-daily dosing.

No dosage adjustment is necessary in elderly patients, or in patients with hepatic impairment or mild to severe renal impairment.

Nephropathy in Type 2 Diabetic Patients

The recommended target maintenance dose is 300 mg once daily. There are no data on the clinical effects of lower doses of AVAPRO on diabetic nephropathy (seeCLINICAL PHARMACOLOGY: Clinical Studies).

Volume- and Salt-Depleted Patients

A lower initial dose of AVAPRO (75 mg) is recommended in patients with depletion of intravascular volume or salt (eg, patients treated vigorously with diuretics or on hemodialysis) (see WARNINGS: Hypotension in Volume- or Salt-Depleted Patients).
