CLINICAL PHARMACOLOGY
MECHANISM OF ACTION
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. Spironolactone causes increased
amounts of sodium and water to be
excreted, while potassium is retained. Spironolactone acts both as a
diuretic and as an antihypertensive
drug by this mechanism. It may be given alone or with other diuretic
agents that act more proximally in
the renal tubule.
ALDOSTERONE ANTAGONIST ACTIVITY: Increased levels of the
mineralocorticoid, aldosterone, are present
in primary and secondary hyperaldosteronism. Edematous states in which
secondary aldosteronism is
usually involved include congestive heart failure, hepatic cirrhosis,
and nephrotic syndrome. By
