The name of your medicine is COVERAM. The medicine contains the active ingredient perindopril arginine. Perindopril belongs to a group of medicines called angiotensin converting enzyme (ACE) inhibitors. It also contains the active ingredient amlodipine besilate.

The active ingredients in COVERAM, perindopril arginine and amlodipine help lower your blood pressure. COVERAM works by widening your blood vessels, which reduces pressure in the vessel, making it easier for your heart to pump blood around your body. This helps increase the supply of oxygen to your heart, so that when you place extra demands on your heart, such as during exercise, your heart may cope better and you may not get short of breath as easily.
