Patient leaflet - Eprosartan 400 mg film-coated tablets

1. What Eprosartan is and what it is used for

Eprosartan 300mg, 400mg and 600mg film-coated tablets contains a medicine called eprosartan mesilate. This belongs to a group of medicines called ‘angiotensin II receptor antagonists’. This medicine is used to treat high blood pressure, also called hypertension.

The main cause of high blood pressure is narrowing of the blood vessels. This increases the amount of work your heart must do to pump blood around your body. You may not feel unwell, but if high blood pressure is not treated, it can lead to heart disease and stroke. How Eprosartan works:

Angiotensin II is a chemical found in the body which makes your blood vessels contract.

This makes it more difficult for blood to pass through them This causes your blood pressure to rise

Eprosartan works by preventing the chemical, angiotensin II, from causing your blood vessels to contract. This has the effect of lowering your blood pressure.

You may be given Eprosartan on its own or with another medicine used to treat high blood pressure. Using both medicines together will lower your blood pressure more than one on its own.

The active ingredient in this medicine is eprosartan mesilate. This is the new name for eprosartan mesylate. The active ingredient itself has not changed.

2. What you need to know before you take Eprosartan
