Benatus-LS is a combination of Ambroxol, Levosalbutamol and Guaifenesin.
Ambroxol is a mucolytic which 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 airways. Guaifenesin is an expectorant which decreases the stickiness of mucus (phlegm) and helps in its removal from the airways.
