potassium guaiacolsulfonate

Potassium guaiacolsulfonate is a small molecule expectorant and mucolytic agent used to alleviate symptoms of cough and chest congestion associated with respiratory tract infections, asthma, and the common cold. It functions through a physicochemical mechanism, acting directly on respiratory tract mucus to decrease its viscosity and stickiness. By thinning the phlegm, it facilitates more productive coughing and easier clearance of the airways. While it is frequently utilized as a component in multi-ingredient upper respiratory combination products alongside antitussives or other expectorants, it is a well-established generic compound with no single primary developer.
