Absorption is unstable. It binds to a high degree with erythrocytes, much less is associated with plasma proteins.
T 1/2 long, is 40-60 hours.

It is excreted mainly unchanged in the urine.

In elderly patients excretion slows down, in comparison with patients of young and middle age, absorption does not change.

INDICATIONS
Arterial hypertension.
Edema syndrome of various etiologies (chronic heart failure, nephrotic syndrome, liver cirrhosis).
DOSING MODE
Install individually.
With arterial hypertension - 25 mg 1 time / day. If necessary, the dose can be increased to 50-100 mg / day.
