Web1 feb. 1994 · Investigation of the possible effect of ranitidine on morphine glucuronidation indicated by clinical studies and later confirmed in vitro found no significant effect on the urinary M3G/M6G ratio, and possible explanations to the apparent incongruity between the serum and urine data are discussed. 29 Web16 dec. 2024 · 4.2. The Influence of Sorafenib on the Pharmacokinetics of Morphine and M3G. Since the role of P-gp in the pharmacokinetics of morphine and its glucuronidated metabolites is unclear, we investigated the effect of one of the more potent P-gp inhibitors—sorafenib—on the pharmacokinetics of morphine and its M3G metabolite in …
Web11 sept. 2012 · For morphine, the metabolite morphine-3-glucuronide (M3G) is commonly believed to underlie this phenomenon.

Incorporation of delay and metabolite compartments did not alter the morphine mass …
Morphine-3-glucuronide is a metabolite of morphine produced by UGT2B7. It is not active as an opioid agonist, but does have some action as a convulsant, which does not appear to be mediated through opioid receptors, but rather through interaction with glycine and/or GABA receptors.
