This product consists of two active ingredients; perindopril tert-butylamine and indapamide. Perindopril tert-butylamine is a medicine that belongs to a class of medications known as “angiotensin converting enzyme (ACE) inhibitor”. it acts by widening the blood vessels making it easier for your heart to pump blood through them. Indapamide belongs to a class of medicines known as “diuretics”. Diuretics act by increasing the urinary output that your kidneys produce. Indapamide is different compared to other diuretics because it does not cause excessive urination. This combination of active ingredients is used to help reduce and control your blood pressure if you have hypertension (high blood pressure).
