The principal use of guaifenesin powder is in the treatment of coughing, but the drug has numerous other uses,including medical, veterinary, and personal.Guaifenesin is thought to act as an expectorant by increasing the volume and reducing the viscosity of secretions in the trachea and bronchi. It also stimulates the flow of respiratory tract secretions, allowing ciliary movement to carry the loosened secretions upward toward the pharynx.Thus, it may increase the efficiency of the cough reflex and facilitate removal of the secretions.
