Guiaphenesin Indication

Used to assist the expectoration of phlegm from the airways in acute respiratory tract infections.

Guiaphenesin Pharmacology

Guaifenesin is an expectorant which increases the output of phlegm (sputum) and bronchial secretions by reducing adhesiveness and surface tension. The increased flow of less viscous secretions promotes ciliary action and changes a dry, unproductive cough to one that is more productive and less frequent. By reducing the viscosity and adhesiveness of secretions, guaifenesin increases the efficacy of the mucociliary mechanism in removing accumulated secretions from the upper and lower airway.

Rapidly absorbed from the GI tract
