Captopril
Captopril (rINN) (pronounced /ˈkæptəprɪl/) is an angiotensin-converting enzyme inhibitor (ACE inhibitor) used for the treatment of hypertension and some types of congestive heart failure. The drug works by relaxing the blood vessels, allowing them to dilate and ease blood flow. It may take up to several weeks to achieve full benefits even though captoril quickly lowers blood pressure. If you have suffered heart failure you could be given captopril as well as a diuretic as it can achieve excellent results in relaxing muscles in the walls of the blood vessel which in turn reduces the workload on the heart. The first dose would be small and taken it while lying down would be of benefit as there is a possibility that it may cause a sudden drop in blood pressure. Some people may suffer from side effects if this is so then a reduction in the amount taken may be of help.
A major risk with this medication is that blood pressure may fall to low. Because of this reason when taking the first dose of captopril you would be advised to sit or lie down. If you have unstable blood pressure this medication would be prescribed with caution.
