Contents of the pack and other information
Irbesartan/Hydrochlorothiazide NORMON 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 by the body that binds to receptors in blood vessels, causing them to constrict. This results in an increase in blood pressure. Irbesartan blocks the binding of angiotensin-II 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 NORMON work together to achieve a greater reduction in blood pressure than either substance alone.
Irbesartan/Hydrochlorothiazide NORMON is used to treat high blood pressure, when treatment with irbesartan or hydrochlorothiazide alone does not provide adequate control of blood pressure.
Do not take Irbesartan/Hydrochlorothiazide NORMON:
Irbesartan/Hydrochlorothiazide NORMON should not be given to children and adolescents (under 18 years of age).
