What this medicine is and what it is used for

Captopril belongs to a group of medicines called

Angiotensin Converting Enzyme (ACE) Inhibitors.

These work by helping to widen your blood vessels,

which then make it easier for your heart to pump

blood through them.

Captopril is used to treat the following:

■    Mild to moderately high blood pressure (hypertension)

■    Severely high blood pressure (hypertension) where standard treatment is ineffective or unsuitable

■    Treatment or prevention of heart failure

■    Short-term (4 weeks) treatment within the first 24 hours of a heart attack
