IV. Uses of Karvezide

A. Primary Indications

Karvezide is a medicine that contains the active substance irbesartan and hydrochlorothiazide. It is used to treat essential hypertension and renal disease in patients with hypertension and type-2 diabetes mellitus as part of an antihypertensive medicinal product regimen 1. Karvezide is an angiotensin-II-receptor antagonist that blocks the action of a hormone in the body called angiotensin II. By blocking the receptors to which angiotensin II normally attaches, irbesartan stops the hormone having an effect, allowing the blood vessels to widen. This allows the blood pressure to drop, reducing the risks associated with high blood pressure, such as having a stroke 1.

Karvezide was more effective than placebo (a dummy treatment) and than hydrochlorothiazide alone in reducing diastolic blood pressure. Increasing the dose to 300 mg irbesartan and 25 mg hydrochlorothiazide may give a further decrease in blood pressure 1.
