The duration of the course of treatment is determined by the attending physician.

The therapeutic effect of CLASTA on indicators reflecting the course of bronchial asthma develops during the first day.

Drug interactions

KLAST can be used with other drugs for the prevention and long-term treatment of asthma without increasing side effects.

KLAST at the recommended dose did not cause clinically significant changes in the pharmacokinetics of the following drugs: theophylline, prednisone, prednisolone, oral contraceptives (norethindrone 1 mg / ethinyl estradiol 35 μg), terfenadine, digoxin, warfarin.

The area under the plasma concentration curve (AUC) decreased in approximately 40% of patients with co-administration of phenobarbital, however, correction of the KLAST dosage regimen is not required in such patients.

Since montelukast is metabolized by CYP A4, caution should be exercised, especially in children, when KLAST is used in conjunction with CYP 3A4 inducers such as phenytoin, phenobarbital and rifampicin.

Treatment with bronchodilators: KLAST can be added to the treatment of patients in whom bronchial asthma is not controlled by the use of bronchodilators alone. When a therapeutic effect is achieved (usually after the first dose) during therapy with KLAST, the dose of bronchodilators can be gradually reduced.

Inhaled glucocorticosteroids: Treatment with KLAST provides an additional therapeutic effect for patients receiving treatment with inhaled glucocorticosteroids. When stabilization of the patient's condition is achieved, it is possible to reduce the dose of glucocorticosteroids. The dose of glucocorticosteroids should be reduced gradually, under the supervision of a physician. In some patients, the intake of inhaled glucocorticosteroids can be completely canceled. Abrupt replacement of therapy with inhaled glucocorticosteroids by the appointment of CLAST is not recommended.

Preparations containing St. John's wort may reduce plasma levels of montelukast.

Special instructions

CLAST is not intended for relief of bronchospasm in acute asthma attacks, as well as for the treatment of status asthmaticus.

In the acute course of bronchial asthma, it is recommended to use appropriate drugs to treat patients. In the acute phase of bronchial asthma, CLAST treatment can be continued.

Even with a gradual, controlled dose reduction of an inhaled glucocorticosteroid, CLAST should not be immediately prescribed instead of an inhaled corticosteroid.

Features of the effect of the drug on the ability to drive vehicles or potentially dangerous mechanisms

CLAST can cause headache, drowsiness, lethargy, and slowness. This should be taken into account if it is necessary to use the drug in persons whose activities are related to driving, servicing machines and mechanisms, and performing work in an unstable position.



Symptoms: dehydration, drowsiness, mydriasis, hyperkinesia, abdominal pain.
Treatment is symptomatic. There are no data on the possibility of excretion of montelukast by peritoneal dialysis or hemodialysis.
