Mechanism of action: Aldactone (spironolactone) is a specific pharmacologic antagonist of aldosterone, acting primarily through competitive binding of receptors at the aldosterone-dependent sodium-potassium exchange site in the distal convoluted renal tubule.

How does spironolactone work as a diuretic?

Spironolactone works by blocking the actions of a hormone in the body called aldosterone. This hormone is produced by glands found above the kidneys called the adrenal glands. Aldosterone acts in the kidneys, where it is involved in controlling the balance of salt and water in the body.

• leg cramps.
• headache.
• dizziness.
• drowsiness.

What is the mechanism of action and the primary role of spironolactone in the treatment of heart failure?

Spironolactone antagonizes the effect of aldosterone and can lead to a reduction in fibrosis and an improvement in left ventricular (LV) function.

What is the drug spironolactone used for?

Spironolactone is used in combination with other medicines to treat high blood pressure (hypertension) and heart failure. Lowering blood pressure can reduce the risk of strokes and heart attacks.

Does spironolactone lower BP?

Spironolactone is used in combination with other medicines to treat high blood pressure (hypertension) and heart failure. Lowering blood pressure can reduce the risk of strokes and heart attacks. Spironolactone is also used to lessen the need for hospitalization for heart failure.

Our retrospective chart review shows that in our practice, spironolactone is effective in raising serum potassium in PD patients regardless of the indication for use. Among patients treated for low serum potassium, it was effective in raising potassium to a normal range.

What is the advantage of eplerenone over spironolactone?

A major advantage of eplerenone over the nonselective aldosterone receptor antagonist spironolactone is lack of binding to progesterone and androgen receptors, which is associated with drug-induced gynecomastia, breast pain, and impotence.

Why do we use spironolactone in heart failure?

It can be used in addition to agents such as angiotensin-converting enzyme inhibitors and beta blockers, which also decrease mortality, and diuretics and digoxin, which are useful in treating symptoms.

These results indicate that (a) at the dosages used in the study, spironolactone is more effective than furosemide in nonazotemic cirrhosis with ascites, and (b) the activity of the renin-aldosterone system influences the diuretic response to furosemide and spironolactone in these patients.

What's the difference between Aldactone and spironolactone?

People taking spironolactone should avoid potassium supplements, potassium-containing salt substitutes (Morton Salt Substitute, No Salt, Lite Salt, and others), and even high-potassium foods (primarily fruit).

Is spironolactone the same as furosemide?

Furosemide is a diuretic which removes extra water and certain electrolytes from the body through urine. Over time, it also relaxes blood vessels, but causes potassium loss. Spironolactone is also a diuretic which conserves potassium, thereby balancing its levels in the body.
