codeine phosphate + guaifenesin

Codeine phosphate + guaifenesin is a combination pharmaceutical drug used primarily to relieve cough and loosen mucus in conditions such as the common cold or allergies. Codeine is an opioid that acts centrally on the medulla to suppress the cough reflex, while guaifenesin is an expectorant that thins and loosens bronchial secretions, making it easier to clear mucus from the airways. This combination provides both symptomatic relief of cough (via central suppression) and improved clearance of respiratory secretions (via increased fluidity). Codeine has potential for dependence and should be used only as prescribed for short durations[1][2][5].
