Pharmachologic effect Aldactone 100mg

Aldactone 100mg Potassium-magnesium diuretic. It is a competitive aldosterone antagonist on the effect on the distal nephron (competes for binding sites on the cytoplasmic protein receptors, reduces the synthesis of permeases in the aldosterone-dependent portion of the collecting tubules and distal tubules), increases the excretion of Na +, Cl- and water and reduces the excretion of K + and urea, reduces titrated acidity of urine. Increased diuresis causes a hypotensive effect, which is not constant. The hypotensive effect does not depend on the level of renin in the blood plasma and does not manifest itself in normal blood pressure.

The diuretic effect is manifested at 2-5 days of treatment.
