Dosage and administration:

Inside With liver cirrhosis with a Na + / K + ratio less than 1, the daily dose is 100 mg, if the ratio is more than 1 – 200-400 mg / day. When nephrotic syndrome: 100-200 mg / day in combination with thiazide diuretics. When edematous syndrome: 100-200 mg / day in 2-3 doses, in combination with a “loop” or thiazide diuretic. Assign daily, for 5 days, then, depending on the effect, the daily dose is reduced to 25-35 mg or gradually increased to 200-400 mg in 2-4 doses.

Correction of the dosing regimen is carried out taking into account the plasma K + concentration. With pronounced hyperaldosteronism and reduced K + content in plasma, it is prescribed in a daily dose of 300 mg in 2-3 doses (up to 400 mg / day), while improving the state, the dose is gradually reduced to 25 mg / day.
