Method of administration and dosage
The doctor sets the dose of the drug individually, depending on the hormonal status and the severity of violations of water-electrolyte metabolism.
In the form of a solution, Aldactone is administered intravenously at 100-200 mg (1-2 ampoules) per day for 3-5 days. The maximum daily dose is 800 mg.
In the form of tablets, the drug should be taken orally. Recommended doses for adults:
- Primary hyperaldosteronism: during preparation for surgery - 100-400 mg per day; in case of refusal from the operation, the patient is selected the minimum effective dose;
- Edema (renal, hepatic and cardiac origin): the initial daily dose is 100 mg in several doses, after 5 days, depending on the achieved clinical effect and the concentration of potassium in the blood plasma, the dose is increased to 200 mg or reduced to 25 mg. The duration of treatment is 14-21 days. If necessary, courses are repeated at intervals of 10-14 days;
- Diuretic-induced hypokalemia: 25-100 mg per day;
- Arterial hypertension: the initial daily dose is 50-100 mg in several doses, after 2 weeks, depending on the effect, the dose may be reduced or increased.
For children, Aldactone is prescribed in a daily dose calculated taking into account weight - 3.3 mg / kg.

- From the digestive system: diarrhea or constipation, abdominal pain, nausea, gastritis, vomiting, ulceration and bleeding in the gastrointestinal tract, intestinal colic;
- From the hematopoietic system: thrombocytopenia, megaloblastosis, agranulocytosis;
- From the side of metabolism: hyperuricemia, hypercreatininemia, increased urea concentration, disturbances in water-salt metabolism and acid-base balance (metabolic hypochloremic acidosis, alkalosis);
- From the endocrine system: in women - hirsutism, soreness of the mammary glands, coarsening of the voice, amenorrhea, dysmenorrhea, metrorrhagia in the climacteric period, breast carcinoma; in men with prolonged use - erectile dysfunction, gynecomastia;

special instructions
During treatment, you should periodically determine the content of urea and electrolytes in the blood.
Simultaneously with Aldactone, potassium-containing drugs and other diuretics should not be prescribed that cause potassium retention in the body. It is recommended to refrain from using carbenoxolone, because it causes sodium retention.
If necessary, the combined use of spironolactone with antihypertensive drugs or other diuretics should reduce the dose of the latter. The same goes for the simultaneous use of digoxin.
Drug interactions
- Antihypertensive drugs: the antihypertensive effect of spironolactone is potentiated;
- Potassium preparations, other potassium-sparing diuretics, table salt substitutes, potassium-containing biologically active food additives, as well as losartan, candesartan and eprosartan: the risk of hyperkalemia increases;
- Mefenamic acid, indomethacin: excretion of canrenone (active metabolite of spironolactone) by the kidneys is inhibited;
- Salicylates: the diuretic effect of Aldactone decreases;
- Digoxin: it is possible to decrease or increase its effects;
- Oral anticoagulants: its hypoprothrombinemic effect decreases;
- Lithium carbonate: the concentration of lithium in the blood plasma may increase;
- Cholestyramine: there is a risk of developing hypochloremic alkalosis;
- Triptorelin, gonadorelin, buserelin: their effect is enhanced;
- Norepinephrine: the sensitivity of the vessels to its action may decrease;
- Angiotensin-converting enzyme inhibitors: Increases the likelihood of developing hyperkalemia, especially with concomitant renal dysfunction.
