DrugBankMechanism of Action
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."
Metabolism
The metabolism of pholcodine seems to be very slow and due to the elimination profile, it is thought that most of the administered dose undergoes metabolism. There is some evidence in preclinical trials that indicate that morphine is a minor metabolite of pholcodine and that it accounts for 1% of the administered dose.

Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
