Coryl-LS is the combination of Ambroxol Hydrochloride, Levosalbutamol & Guaiphenesin Syrup that is used to treat patients having cough with mucus. Ambroxol is a mucolytic that works by thinning and loosening mucus which makes it easy to cough out. While Levosalbutamol is a bronchodilator and Guaiphenesin is an expectorant that usually decreases the stickiness of mucus, Ambroxol Hydrochloride, Levosalbutamol & Guaiphenesin Syrup makes it easier to breathe for the patient.
