What Is Prexum® and What Is It Used For?

Prexum® contains an active ingredient called perindopril arginine, which is part of a group of medicines known as ACE inhibitors (Angiotensin-Converting Enzyme inhibitors). These medications help to relax and widen your blood vessels, which makes it easier for your heart to pump blood around the body.

What Is It Commonly Used For?

• High blood pressure (hypertension): Helps reduce blood pressure and lowers the risk of heart attack, stroke, and kidney problems.
• Heart failure: Assists when the heart struggles to pump blood effectively.
