Bipreterax is a combination of two active ingredients, perindopril andindapamide. It is an anti-hypertensive and is used in the treatment of high blood pressure(hypertension). Bipreterax 5 mg/1.5 mg is prescribed for patients already receiving perindopril 5 mg and indapamide 1.5 mg from separate tablets, these patients may instead receive one tablet of Bipreterax 5 mg/1.5 mg which contains both ingredients. Perindopril belongs to a class of medicines called ACE inhibitors. These work by widening the blood vessels, which makes it easier for your heart to pump blood through them. Indapamide is a diuretic. Diuretics increase the amount of urine produced by the kidneys. However, indapamide is different fromother diuretics, as it only causes a slight increase in the amount of urine produced. Each of the active ingredients reduces blood pressure and they work together to control your blood pressure.
