Megavent Pd Syrup is used for supporting respiratory relief and airway comfort. It combines Terbutaline, Guaiphenesin, Ambroxol, and Menthol to support respiratory health. The formulation helps in loosening thick mucus, making it easier to expel, while also assisting in reducing airway tightness. Terbutaline works by relaxing airway muscles, Ambroxol helps clear congestion, and Guaiphenesin improves mucus clearance. Menthol further adds a cooling effect, soothing irritation in the throat. Together, these ingredients assist in improving breathing, reducing discomfort, and supporting overall respiratory comfort.
