WebIn humans, N-demethylation of oxycodone to noroxycodone by CYP3A4 is the major metabolic pathway, accounting for 45% ± 21% of a dose of oxycodone, while O-demethylation of oxycodone into oxymorphone by CYP2D6 and 6-ketoreduction of oxycodone into 6-oxycodols represent relatively minor metabolic pathways, … Web21 feb. 2011 · Recently, Cone et al⁵ reported that in some patients chronically treated with morphine, hydromorphone can appear in the urine as a result of a minor metabolic pathway. An extended-release oxymorphone (OpanaER) and an immediate-release oxymorphone (Opana) have recently become available.

WebThe metabolism of hydrocodone was studied in man, rat, guinea pig, rabbit, and dog. Routes of metabolism included O-demethylation, N-dealkylation, and 6-keto-reduction to the corresponding 6-alpha- and 6-beta-hydroxy metabolites, where each metabolic pathway produces an active metabolite.
