| Working & Treatment of
Spironolactone – Aldactone |
According to the pharmacological term Aldactone-Spironolactone is
antagonist of aldosterone which functions basically through
competitive binding receptors at the aldosterone dependent, sodium
potassium exchange site within the distal complex renal tubule. The
drug causes enhanced amounts of sodium and water to be expelled out
while diminishing the loss of potassium. This medication is designed
to function both as the diuretic as well as the anti-hypertensive
drug through such mechanism. The drug could be given singly as well
as along with certain other medications that are diuretic agents
acting rather proximally in the renal tubule.
Aldactone-Spironolactone is also found to improve the levels of
mineralocorticoid, aldosterone that are present in the primary and
secondary hyperaldosteronism. Edematous conditions wherein the
secondary aldosteronism is normally responsible are such as:
congestive heart failure, hepatic cirrhosis and nephritic syndromes.
The drug by competing with aldosterone for receptor sites provides
efficient therapy for the edema and ascites in those typical
conditions. The medication work against secondary aldosteronism
caused due to the quantity diminution as well as related sodium loss
resulted due to the diuretic therapy.
Aldactone-Spironolactone is also very efficient in reducing the
systolic and diastolic blood pressures in the patients suffering
from the primary hyperaldosteronism. The drug is also considered the
most effective in majority cases of essential hypertension in spite
of the fact that aldosterone release may be within standard limits
in conditions like benign essential hypertension. The drug inhibits
the exchange of sodium for potassium in the distal renal tubule and
helps avoiding potassium loss in spite its function of antagonizing
the aldosterone effects.
