DESCRIPTION
Spironolactone Tablets, USP contain 25 mg, 50 mg, or 100 mg of the
aldosterone antagonist
spironolactone,
17-hydroxy-7α-mercapto-3-oxo-17α-pregn-4-ene-21-carboxylic acid
γ-lactone acetate,
which has the following structural formula:
Spironolactone is practically insoluble in water, soluble in alcohol,
and freely soluble in benzene and in
chloroform.
Inactive ingredients include calcium sulfate, hypromellose, magnesium
stearate, microcrystalline
cellulose, N & A mint flavor, polyethylene glycol, polysorbate 80,
povidone, pregelatinized starch,
sodium starch glycolate, talc, and titanium dioxide.
ACTIONS/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 which 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 the nephrotic
syndrome. By competing with aldosterone
for receptor sites, spironolactone provides effective therapy for the
edema and ascites in those
conditions. Spironolacto
