Guaifenesin, a glyceryl ether of guaiacol, is a key constituent in cold and cough formulations. It belongs to the group of expectorant medicines because of its ability to ease the discomfort caused due to cough by causing an increase in the sputum volume and a simultaneous decrease in its viscosity. Its applications include short term relief in the breathing passageway in various conditions such as allergy, cold, and upper respiratory tract infections. It has also been proposed to be effective in the management of pain in various conditions such as prostatitis, seminal vesiculitis, benign prostatic hypertrophy, prostatic abscess, bladder neck hypertrophy, dysmenorrhea, and urinary tract infection.
