Chemical compound

Morphine-3-glucuronide is a metabolite of morphine produced by UGT2B7.^[1] It is not active as an opioid agonist,^[2] but does have some action as a convulsant, which does not appear to be mediated through opioid receptors,^[3] but rather through interaction with glycine and/or GABA receptors. As a polar compound, it has a limited ability to cross the blood–brain barrier, but kidney failure may lead to its accumulation and result in seizures. Probenecid and inhibitors of P-glycoprotein can enhance uptake of morphine-3-glucuronide and, to a lesser extent, morphine-6-glucuronide.^[4]^{[page needed]} Reported side effects related to the accumulation of this metabolite include convulsions, agitation, hallucinations, hyperalgesia, and coma.
