Leukast (Montelukast)

Montelukast blocks the cysteinyl leukotriene receptor CysLT1, preventing leukotrienes from causing airway narrowing, mucus production, and inflammation. By inhibiting this pathway, it reduces bronchoconstriction and allergic responses in the respiratory tract.

The dosage of Leukast is determined by a qualified prescriber based on the patient’s age, weight, and specific condition. Healthcare professionals select the appropriate strength and dosing schedule according to clinical guidelines.

Leukast is classified as Pregnancy Category B, indicating no evidence of risk in animal studies but limited human data. It may be used during pregnancy only if the potential benefit justifies the risk, and breastfeeding mothers should consult their physician.

To request Leukast, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Leukast belongs to the leukotriene receptor antagonist class, offering an oral alternative to inhaled corticosteroids or long‑acting beta‑agonists. It is particularly useful for patients with aspirin‑intolerant asthma or those who need additional control beyond inhaled therapy, though it does not replace rescue bronchodilators.

Leukast tablets should be stored at ambient temperature, preferably below 25 °C. Keep them in the original container, protect from moisture and direct sunlight, and ensure they are out of reach of children.

Leukast is taken orally, usually once daily in the evening, with or without food, as directed by the prescribing clinician. Swallow the tablet whole; do not crush or chew unless specifically instructed.

Serious adverse events, though rare, include severe allergic reactions such as rash, hives, swelling, or anaphylaxis, as well as neuropsychiatric effects like depression, suicidal thoughts, or behavior. Patients should seek immediate medical attention if any of these symptoms occur.

Leukast is contraindicated in individuals with known hypersensitivity to montelukast or any component of the formulation. It should also be used with caution in patients with severe liver impairment, and it is not recommended for children under the age approved for the specific dosage form.
