Aldactone, also known as spironolactone, is a potassium-sparing diuretic used to treat conditions such as hypertension and heart failure. It works by inhibiting the effects of aldosterone in the kidneys, promoting sodium excretion while retaining potassium.
congrats on reading the definition of Aldactone. now let's actually learn it.
Aldactone is classified as a potassium-sparing diuretic, preventing the loss of potassium when used.
It is commonly prescribed for patients with congestive heart failure to reduce fluid retention and improve symptoms.
Spironolactone can be used in combination with other diuretics to enhance therapeutic effects while minimizing potassium loss.
Common side effects include hyperkalemia (elevated potassium levels), gynecomastia (breast enlargement in men), and gastrointestinal disturbances.
Aldactone also has anti-androgenic properties, making it useful for treating conditions like hirsutism (excessive hair growth) and acne.
