CAPTOPRIL

COMMON BRAND NAME(S): Capoten

GENERIC NAME(S): CAPTOPRIL

 

Description: Captopril competitively inhibits the conversion of angiotensin I (ATI) to angiotensin II (ATII), thus resulting in reduced ATII levels and aldosterone secretion. It also increases plasma renin activity and bradykinin levels. Reduction of ATII leads to decreased Na and water retention. This promotes vasodilation and BP reduction.

Captopril, ACE inhibitor, lowers blood pressure by relaxing blood vessels so that blood can flow more easily. It is also used to treat heart failure, protect the kidneys from harm due to diabetes, and to improve survival after a heart attack.

How to use captopril

Take this medication by mouth on an empty stomach (at least 1 hour before meals) as directed by your doctor, usually two to three times a day.

The dosage is based on your medical condition and response to treatment.

Use this medication regularly in order to get the most benefit from it. To help you remember, take it at the same times each day. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick.

For the treatment of high blood pressure, it may take up to 2 weeks before you get the full benefit of this medication. For the treatment of heart failure, it may take weeks to months before you get the full benefit of this medication. Tell your doctor if your condition does not improve or if it worsens (such as your blood pressure readings remain high or increase).
