Dihydrocodeine is metabolised by the CYP450 system isoenzyme 2D6 to dihydromorphine, which mediates the majority of its analgesic effects. Owing to the low oral bioavailibility of dihydrocodeine (20%), and its subsequent metabolism to active<unk> mpounds, it is likely that doses below 30mg are sub therapeutic for analgesia.
