Costus AP Syrup is a combination mucolytic, expectorant, and bronchodilator oral syrup used for the effective management of productive (wet) cough associated with respiratory tract infections and bronchial congestion. It helps in thinning thick mucus, improving airway clearance, and easing breathing difficulty.

This formulation contains Acebrophylline, Terbutaline Sulphate, and Guaifenesin, which work synergistically to provide comprehensive respiratory relief. Acebrophylline helps reduce airway inflammation and improves mucus clearance, Terbutaline relaxes bronchial smooth muscles to open airways, and Guaifenesin acts as an expectorant that loosens and expels mucus from the respiratory tract.
