Spironolactone belongs to a group of medications known as the potassium-sparing diuretics. It acts in the kidney to remove excess water from the blood into the urine. Spironolactone blocks the actions of a hormone called aldosterone, which causes an increase in the removal of salts such as sodium from the blood. This removal of salts causes water to be drawn out of the blood and into the kidneys, where it is then excreted in the urine. Removing water from the blood causes a decrease in the volume of fluid circulating through the blood vessels. This drop in fluid volume decreases the effort required by the heart to pump blood around the body.
There are many conditions which may lead to an accumulation of fluid in the body (oedema). Spironolactone is commonly used in conditions such as heart failure, where the pumping mechanism of the heart is less effective. It is used to relieve the symptoms of heart failure, such as the shortness of breath seen with fluid on the lungs. It is also used to remove excess fluid associated with liver failure, as well as in the treatment of excessive levels of aldosterone (hyperaldosteronism).
Spironolactone does not increase the loss of potassium from the body in the urine, therefore there is less risk of developing low potassium levels in the blood (hypokalaemia). When it is used alone it has a weak effect, therefore it is often used in combination with other diuretics.

Aldactone Directions To Use
Athletes must strictly observe that during the use of Aldactone no additional potassium is taken since this would cause a life-threatening increase in the serum potassium level. Lotassiumsparing diuretics have relatively low diuretic effects so that Aldactone can be called a mild diuretic. It is interesting to note that Aldactone is also an antiandrogen since it reduces the androgen level. Female athletes take advantage of spironolactone characteristic by using it to minimize the virilization symptoms during steroid treatment or the symptoms after treatment. For this purpose spironolactone is normally taken daily for 10 to 14 days, ustially in a dose of 50 mg/day. In men this could cause problems since the relationship of the androgen level to the estrogen level changes in favor of the latter. Thus, common side effects of Aldactone in men include pain in the nipples and breast swelling (gynecomastia).
