Aldactone 25


Condition: New Tablet Content: 25mg 30 pills Tablet Manufacturer: RPG Tablet Chemical Name: Aldactone (Spironolactone)


Potassium, magniysberegayuschy diuretic. It is a competitive antagonist of aldosterone for influencing the distal nephron (competes for binding sites on the cytoplasmic protein receptors, reduces the synthesis permeases in aldosterone-sensitive portion of the collecting ducts and distal tubules), increases the excretion of Na + , Cl  and water and reduce the excretion of K + and urea, reduces titratable acidity of urine. Increased diuresis causes a hypotensive effect, which is unstable. The hypotensive effect is not dependent on the level of renin in the blood and plasma does not occur in normal blood pressure.

The diuretic effect is seen on the 2-5 day of treatment.
