6.Contents of the pack and additional information

Irbesartán/Hidroclorotiazida NORMON is an association of two active principles, irbesartán and hidroclorotiazida.

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

Hidroclorotiazida belongs to the group of medications (called thiazide diuretics) that increase the amount of urine eliminated, reducing blood pressure.

The two active principles of Irbesartán/Hidroclorotiazida NORMON act together to achieve a decrease in blood pressure greater than that obtained with each one separately.

Irbesartán/Hidroclorotiazida NORMON is used to treat high blood pressure, when treatment with only irbesartán or only hidroclorotiazida does not provide adequate control of your blood pressure.
