Aceten (Captopril)


Aceten (Captopril) is used in the treatment of high blood pressure and congestive heart failure. When prescribed for high blood pressure, it is effective used alone or combined with diuretics. If it is prescribed for congestive heart failure, it is used in combination with digitalis and diuretics. This drug is in a family of drugs known as angiotensin converting enzyme (ACE) inhibitors. It works by preventing a chemical in your blood called angiotensin I from converting into a more potent form that increases salt and water retention in your body. It also enhances blood flow throughout your blood vessels.

Aceten (Captopril) should be taken 1 hour before meals. If you are taking an antacid, take it 2 hours prior to Aceten (Captopril). Take this medication exactly as prescribed. Stopping Aceten (Captopril) suddenly could cause your blood pressure to increase.
