1. What is Irbesartan Hydrochlorothiazide Zentiva and what is it used for

Irbesartan Hydrochlorothiazide Zentiva is a combination of two active substances, irbesartan and hydrochlorothiazide.

Irbesartan belongs to a group of medicines known as angiotensin-II receptor antagonists. Angiotensin-II is a substance produced in the body that binds to receptors in blood vessels, causing them to constrict. This results in an increase in blood pressure. Irbesartan prevents angiotensin-II from binding to these receptors, relaxing blood vessels and reducing blood pressure.

Hydrochlorothiazide belongs to a group of medicines (called thiazide diuretics) that increase the amount of urine excreted, reducing blood pressure.

The two active substances in Irbesartan Hydrochlorothiazide Zentiva work together to achieve a greater reduction in blood pressure than either substance alone.

Irbesartan Hydrochlorothiazide Zentiva is used to treat high blood pressure, when treatment with irbesartan or hydrochlorothiazide alone does not provide adequate control of blood pressure.
