Drug Name
Capoten (Captopril)

Drug Uses
Capoten can be used alone in treating high blood pressure. Its blood pressure lowering effect can be further enhanced by the addition of a diuretic (water pill) medication. Capozide is an example of a medication that combines the effect of capoten with a diuretic (water pill). By reducing resistance in the arteries, capoten can be useful in the treatment of congestive heart failure. In treating heart failure, capoten usually supplements conventional treatment, including a diuretic and digoxin (Lanoxin). After a heart attack, capoten has been found to be effective in improving functioning of the damaged heart. It is also used to treat kidney disease associated with diabetes.

How to use
Capoten should be taken on an empty stomach one hour before meals. Do not take antacids containing aluminium or magnesium within 1 hour before or 2 hours after taking this medicine.

Drug Class and Mechanism
Capoten is an ACE (angiotensin converting enzyme) inhibitor. ACE is an enzyme in the body which is important for the formation of angiotensin II. Angiotensin II causes constriction of arteries in the body, thereby elevating blood pressure. ACE inhibitors such as captopril lower blood pressure by inhibiting the formation of angiotensin II, thus relaxing the arteries. Relaxing the arteries not only lowers blood pressure, but also improves the pumping efficiency of a failing heart and improves cardiac output in patients with heart failure.
