Aldactone (spironolactone) is an aldosterone receptor antagonist that causes the kidneys to remove water and sodium from the body, with reduced losses of potassium. It’s in the class of drugs known as ‘potassium-sparing’ diuretics. Generally, Aldactone is used to reduce edema (swelling) caused by heart, liver or kidney problems, hypertension, and for patients with hyperaldosteronism.
Potassium sparing diuretics are diuretic drugs that do not promote the secretion of potassium into the urine. They are typically used as part of a drug stack or with loop diuretics. For example, in patients with high blood pressure or heart failure. The danger of using this drug incorrectly is raising potassium levels beyond the normal range, which can result in arrhythmias (irregular heartbeat).
Aldactone is listed on the World Health Organization’s List of Essential Medicines, which means its considered an important medication needed in a basic health system. Bodybuilders have used this drug as a diuretic several days leading up to competition to help with their goal of a ripped and dry physique.
