Pathway Description
Ketobemidone metabolic pathway
Homo sapiens
Metabolic Pathway
Ketobemidone is mainly metabolized by conjugation of the phenolic hydroxyl group, and by N-desmethylation. Only about 13-24% is excreted unchanged after iv. administration.
Ketobemidone (Cliradon, Ketogan, Ketodur, Cymidon, Ketorax, &c.) is a powerful opioid analgesic. It also has some NMDA-antagonist properties. This makes it useful for some types of pain that don't respond well to other opioids. The most commonly cited equalisation ratio for analgesic doses is 25 mg of ketobemidone hydrobromide to 60 mg of morphine hydrochloride or sulfate and circa 8 mg of ketobemidone by injection.
