How Bromline Expectorant works
Bromline Expectorant is a combination of three medicines: Terbutaline, Bromhexine and Guaifenesin which relieve cough with mucus. Terbutaline is a bronchodilator. It works by relaxing the muscles in the airways and widens airways. Bromhexine is a mucolytic which thins and loosens mucus (phlegm), making it easier to cough out. Guaifenesin is an expectorant which decreases the stickiness of mucus (phlegm) and helps in its removal from the airways.
