Contain the active ingredient : Prazosin HCl, which is a type of medicine called an alpha-blocker. Prazosin has some quite different uses. It works by blocking alpha receptors in certain areas of the body.
Alpha receptors are found on the muscle in the walls of blood vessels. When prazosin blocks these receptors it causes the muscle in the blood vessel to relax and the blood vessel to widen. This lets the blood pass more easily through the blood vessels and hence reduces the pressure in the blood vessels. Prazosin can therefore be used to treat high blood pressure.
Widening the blood vessels also decreases the effort required by the heart to pump blood around the body, because there is less resistance for the heart to pump against. Prazosin can therefore also help treat heart failure, where the pumping action of the heart has become less effective.
Prazosin is also used to treat Raynaud's disease and Raynaud's phenomenon, which are conditions where the arteries supplying blood to the hands and feet go into spasm and narrow. This restricts the blood supply to the fingers and toes and causes them to go pale, cold and painful. Prazosin widens the blood vessels and so increases the blood flow to the hands and feet, thus relieving these symptoms.
Alpha receptors are also found on the muscle in the prostate gland. This gland is found only in men and lies at the top of the tube connecting the bladder to the outside (urethra). The prostate gland often enlarges with advancing age (benign prostatic hyperplasia), pressing on the urethra and obstructing the flow of urine from the bladder. This can cause various urinary symptoms such as difficulty passing urine. By blocking the alpha receptors in the prostate, prazosin causes the muscle to relax. This allows urine to flow freely past the prostate gland and relieves the urinary symptoms of this condition.
What is it used for?
High blood pressure (hypertension).
Condition called Raynaud's disease or phenomenon, in which the arteries supplying blood to the hands and feet go into spasm, causing pale, cold and painful fingers and toes.
Enlarged prostate gland (benign prostatic hyperplasia).
