Contents of the pack
Irbesartan Cinfa 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, causing blood vessels 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. Irbesartan slows the progression of kidney damage in patients with high blood pressure and type 2 diabetes.
Irbesartan Cinfa is used in adult patients:
