How Nasdec LS Syrup works

Nasdec LS Syrup is a combination of three medicines: Ambroxol, Levosalbutamol, and Guaifenesin, which relieves cough with mucus. Ambroxol is a mucolytic that thins and loosens mucus (phlegm), making it easier to cough out. Levosalbutamol is a bronchodilator. It works by relaxing the muscles in the airways and widens the airways. Guaifenesin is an expectorant that decreases the stickiness of mucus (phlegm) and helps in its removal from the airways. Together, they make breathing easier.
