title: Differential displacement of opioids from plasma protein binding sites by di-isopropylfluorophosphate in the mouse.
abstract: Di-isopropylfluorophosphate (DFP) displaced the opioid drug, alfentanil, from plasma proteins in-vivo and in-vitro in mice but was without effect on the structurally related compound, fentanyl. This action probably accounts for the enhanced entry of alfentanil into the brain of DFP-treated animals and its enhanced antinociceptive activity.
