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 .
