Pholcodine is an anti-tussive agent that acts primarily on the CNS, causing depression of the cough reflex. It has mild sedative effect with little or no analgesic action.

Pholcodine is indicated as a cough suppressant for the temporary relief of non-productive dry cough. It is stated to present a required label indication of "temporary relief of dry cough". Cough is the respiratory movement that occurs after an irritation signal is transmitted to the central nervous system and further stimulates the medulla oblongata. This stimulation causes a motor output that is sent through motoneurons to the respiratory muscles. A non-productive cough is a type of cough characterized by the absence of sputum, and it has a large inspiration that will cause continuous coughing.
