title: Unexpected opioid activity in a known class of drug.
abstract: Tifluadom, although structurally a 1,4 benzodiazepine, has no affinity for the 3H-flunitrazepam binding site, but is a potent displacer of 3H-bremazocine from its opioid binding site. Tifluadom is characterised as an opiate kappa-receptor agonist in vitro and in vivo with potent analgesic activity in animals and no dependence potential.
