Drug Class: Leukotriene Receptor Antagonist | Form: Chewable Tablet | Prescription Status: Prescription-Only (Rx) — DRAP Registered
What is Beasy 4mg?
Beasy 4mg is a prescription tablet containing Montelukast Sodium 4mg, used for the long-term prevention of asthma symptoms and the relief of allergic rhinitis (دمہ اور الرجی) primarily in children aged 2 to 5 years. Montelukast belongs to the leukotriene receptor antagonist class of medicines and works by blocking leukotrienes, the chemical messengers released in the lungs and airways that cause inflammation, swelling, and excess mucus production. Beasy 4mg is a maintenance medicine taken daily to prevent asthma symptoms from occurring. It is not a rescue medicine and must not be used to treat sudden breathing difficulty or an acute asthma attack.
What is Beasy 4mg Used For?
Asthma Prevention and Maintenance: Taken daily for the long-term control and prevention of chronic bronchial asthma symptoms in children, including wheezing, coughing, and breathlessness. Allergic Rhinitis: Relieves sneezing, runny nose, nasal congestion, and itching caused by seasonal and year-round allergies. Exercise-Induced Bronchoconstriction: Prevents airway narrowing that causes breathing difficulty during or after physical activity. Allergic Cough and Wheezing: Helps control persistent coughing and wheezing associated with allergic conditions in children.
How Does Beasy 4mg Work?
Leukotrienes are inflammatory chemicals released by the immune system in response to allergens and irritants. In the airways, they cause swelling, mucus production, and muscle tightening that leads to asthma symptoms and allergic rhinitis. Montelukast Sodium blocks the leukotriene receptors in the airway cells, preventing leukotrienes from binding and triggering these inflammatory responses. By stopping this process at the receptor level, Beasy 4mg reduces airway inflammation, keeps the airways open, and controls both respiratory and nasal allergy symptoms with once-daily dosing.
