概览

Pholcodine is an opioid antitussive used to suppress unproductive coughing.

作用机制

The mechanism of action of pholcodine is directly performed in the medulla oblongata. In this site, it exerts analgesic properties on the peripheric reflexogenic receptors. This site is commonly known as the "cough center."

适应症

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.
