How codeine metabolism affects its clinical use
https://pharmaceutical-journal.com/article/ld/how-codeine-metabolism-affects-its-clinical-use
WEBApr 27, 2021 · Metabolism. Codeine is primarily metabolised by two different pathways (see Figure) [2] . In most people, around 80% of codeine is conjugated to form codeine-6-glucuronide, which may have weak analgesic activity [2,7] . However, typically less than 10% of codeine undergoes CYP2D6-mediated O-demethylation to …

WEBFeb 13, 2023 · Metabolism: Codeine is metabolized by conjugation to morphine (5% to 10%) and N-demethylation to norcodeine (~10%). Cytochrome P450 2D6 is the principal enzyme responsible for the transformation of codeine to morphine, and P450 3A4 is the major enzyme for converting codeine to norcodeine.

WEBCodeine is metabolised by O- and N-demethylation in the liver to morphine and norcodeine. Hydrocodone is also a metabolite of codeine in humans. Codeine and its metabolites are mostly removed from the body by the kidneys, primarily as conjugates with glucuronic acid.

WEBIntroduction. Codeine is a naturally occurring low-efficacy opium alkaloid. It is usually prepared for medicinal use by methylation of morphine to give a white crystalline powder or fine-needle-shaped white crystals. Odorless, bitter tasting, and affected by light, it is hydrated on exposure to air. Aqueous solutions are acidic and levorotatory.
