How Guaifenesin Tablet Works

Guaifenesin works by enhancing the output of phlegm (sputum) and bronchial secretions. It accomplishes this by decreasing the adhesiveness and surface tension of these materials. This action changes dry, unproductive coughing to more productive and less frequent coughs.

The primary mechanism of guaifenesin involves decreasing the viscosity and adhesiveness of secretions in the airways. This enhances the efficacy of mucociliary activity, which helps remove accumulated secretions from the upper and lower airways. By thinning the mucus, guaifenesin makes it easier for the body's natural cleaning mechanisms to work more effectively.
