Chronic Asthma: For long-term prevention of asthma symptoms. COPD: Managing chronic bronchitis and emphysema. Allergic Rhinitis: Montelukast specifically helps with hay fever symptoms when they coexist with asthma. Exercise-Induced Bronchoconstriction: Preventing airway narrowing triggered by physical activity.

This tablet tackles airway obstruction from two different angles: Doxofylline (SR): The "Sustained Release" (SR) technology allows the medicine to enter your system slowly over many hours. It relaxes the smooth muscles of the lungs by inhibiting phosphodiesterase enzymes. Because it stays in the blood longer, it provides continuous, 24-hour protection against airway tightening. Montelukast Sodium: It blocks "leukotrienes," which are chemicals your body releases when you breathe in an allergen (like pollen). Leukotrienes cause swelling in your lungs and tightening of the muscles around your airways. By blocking them, Montelukast reduces inflammation and mucus production.
