Montek AB Tablet SR is a combination medication comprising Acebrophylline 200mg and Montelukast 10mg, designed to provide effective relief from asthma and chronic obstructive pulmonary disease (COPD) symptoms. Acebrophylline, a bronchodilator, helps to relax bronchial smooth muscle, thereby increasing lung function and reducing bronchospasms. Montelukast, a leukotriene receptor antagonist, inhibits the production of inflammatory mediators, thereby reducing airway constriction and hyperresponsiveness. The sustained-release formulation of Montek AB Tablet SR allows for prolonged absorption and release of the active ingredients, providing up to 24 hours of symptom relief. The medication is suitable for patients with mild to moderate asthma and COPD, including those with exercise-induced bronchospasms. It may be used as monotherapy or in combination with other medications to manage symptoms. As with all medications, Montek AB Tablet SR should be used under the guidance of a healthcare professional and in accordance with the recommended dosage and administration guidelines.
