How Instaryl P Syrup works
Instaryl-P Syrup is a combination of four medicines : Terbutaline, Ambroxol, Guaifenesin, and Levomenthol. Terbutaline is a bronchodilator. It works by relaxing the muscles in the airways and widens airways. This makes breathing easier. Ambroxol is a mucolytic medication. It thins and loosens mucus (phlegm) in the nose, windpipe and lungs making it easier to cough out. Guaifenesin works by decreasing the stickiness of mucus (phlegm) and helps in its removal from the airways. Levomenthol has mild cooling and decongestant properties that help soothe the cough and ease congestion in the lungs.
