.

How to take, the dosage

The drug is taken orally once a day, at any convenient (but at the same time) time, regardless of meals. The tablets should be swallowed without chewing and with plenty of water.

Oedema syndrome in chronic heart failure

The recommended initial dose is 10-20 mg once daily. If necessary, the dose can be doubled until the desired effect is achieved.

Oedema syndrome in renal disease

The recommended starting dose is 20 mg once daily. If necessary, the dose can be doubled until the desired effect is achieved.

Oedema syndrome in liver disease

The recommended starting dose is 5-10 mg once daily. If necessary, the dose can be doubled until the desired effect is achieved.

It is not recommended to exceed the maximum single dose, which is 40 mg (no experience with use).

The drug is used over a long period or until the edema disappears.

Hypertension

The starting dose is 2.5 mg (1/2 tablet of 5 mg) once daily. If there is no therapeutic effect within 4 weeks, the dose is increased to 5 mg once daily. If there is no adequate BP reduction when administered in a dose of 5 mg once daily for 4-6 weeks, the dose is increased to 10 mg once daily. If use of 10 mg/day does not produce the desired effect, an antihypertensive agent from another group should be added to the treatment.

In elderly patients, no dose adjustment is required.

Interaction

Increases the concentration and risk of nephro- and ototoxic effects of cephalosporins, aminoglycosides, chloramphenicol, etacrynic acid, cisplatin, amphotericin B (due to competitive renal excretion).

Effectiveness of diazoxide and theophylline increases, decreases effectiveness of hypoglycemic agents, allopurinol.

Presor amines and thorasemide mutually reduce the effectiveness of each other.

Drugs that block tubal secretion increase the serum concentration of thoracemide.

The simultaneous use of GCS, amphotericin B increases the risk of hypokalemia; with cardiac glycosides – the risk of glycoside intoxication due to hypokalemia (for high- and low-polar) and prolongation of T1/2 (for low-polar) increases.

Decreases renal clearance of lithium preparations and increases the likelihood of intoxication.

The NSAIDs, sucralfate decrease diuretic effect due to inhibition of prostaglandin synthesis, impairment of plasma renin activity and aldosterone excretion.

It increases the antihypertensive effect of hypotensive drugs, neuromuscular blockade of depolarizing myorelaxants (suxamethonium) and weakens the effect of nondepolarizing myorelaxants (tubocurarine).

The simultaneous use of salicylates in high doses with torasemide therapy increases the risk of their toxicity (due to competitive renal excretion).

The sequential or simultaneous use of thorasemide with ACE inhibitors or angiotensin II receptor antagonists may lead to a significant decrease in BP. This can be avoided by reducing the dose of thorasemide or temporarily cancelling it.

The concomitant use of probenecid or methotrexate may decrease the effectiveness of thorasemide (same secretion pathway). On the other hand, thorasemide may lead to decreased renal elimination of these drugs.

The simultaneous use of cyclosporine and thorasemide increases the risk of gouty arthritis due to the fact that cyclosporine may cause impaired urate excretion by the kidneys and thorasemide may cause hyperuricemia.

It has been reported that patients at high risk of nephropathy taking oral thoracemide had more renal dysfunction with radiopaque agents than patients at high risk of nephropathy who underwent IV hydration before radiopaque agents were administered.

The bioavailability and, consequently, the effectiveness of thoracemide may be reduced by co-therapy with colestyramine.

Special Instructions

The drug should be used strictly on prescription.

Patients with hypersensitivity to sulfonamides and sulfonylurea derivatives may have cross-sensitivity to Torasemide-SZ.

Patients receiving Toracemide-SZ at high doses for a prolonged period are recommended a diet with sufficient content of table salt and use of potassium preparations to avoid development of hyponatremia, metabolic alkalosis and hypokalemia.

The increased risk of water-electrolyte balance disorders is noted in patients with renal insufficiency. During the course of treatment it is necessary to monitor the concentration of plasma electrolytes (including sodium, calcium, potassium, magnesium), acid-base status, residual nitrogen, creatinine, uric acid periodically and provide the appropriate corrective therapy if necessary (with higher frequency in patients with frequent vomiting and with parenterally administered fluids).

If azotemia and oliguria appear or worsen in patients with severe progressive renal disease, it is recommended to suspend treatment.

Patients with ascites against liver cirrhosis should be dosed under hospital conditions (electrolyte-water balance disorders may lead to hepatic coma). Regular monitoring of blood plasma electrolytes is indicated for this category of patients.

In patients with diabetes mellitus or with reduced glucose tolerance, periodic monitoring of blood and urine glucose concentrations is required.

In unconscious patients with prostatic hyperplasia, ureteral narrowing, diuresis control is necessary due to the possibility of acute urinary retention.

Influence on driving and operating machinery

Patients must refrain from driving and engaging in other potentially dangerous activities that require increased concentration and quick psychomotor reactions (risk of dizziness and somnolence) during treatment.

In renal failure

The drug is contraindicated in renal failure with anuria, acute glomerulonephritis, acute urinary outflow disorders of any etiology (including unilateral urinary tract involvement).

With cautiousness the drug should be used in case of urine outflow disorders (benign prostatic hyperplasia, narrowing of the urethra or hydronephrosis), hepatorenal syndrome.

In case of liver dysfunction

The drug is contraindicated in hepatic coma and precoma.

The drug should be prescribed with cautious in hepatorenal syndrome.

Children

In older patients no dose adjustment is required.
