Ascoril LS Expectorant 100 ml is a commonly prescribed cough formulation designed for situations where cough is associated with thick mucus and breathing discomfort. It contains a combination of Ambroxol, Guaiphenesin, and Levosalbutamol, which together support mucus loosening, mucus clearance, and airway comfort. This expectorant is often recommended when chest congestion, wheezing, or difficulty in clearing phlegm affects daily breathing comfort, especially during respiratory infections or airway irritation.
