Intrathecal administration of 6-hydroxydopamine (6-OHDA) abolished the antinociceptive effects of acute administration of 5-methoxy-N,N-dimethyltryptamine (5-MeODMT, 1 mg/kg, s.c.) in the hot-plate, tail-flick and shock titration tests of nociception. The antinociceptive effects of 5-MeODMT, abolished by the prior intrathecal 6-OHDA treatment, were restored by intrathecal administration (2 or 1...

In experiments with both rats and mice the 5-HT agonists 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT) and 5-methoxy-N,N-dimethyl-tryptamine (5-MeODMT) were shown to produce reliable analgesic effects after acute administration (1 mg/kg SC) in the tail-flick, hot-plate and shock-titration tests of nociception. Prior treatment with the noradrenaline neurotoxin,...

The effects of the alpha-adrenoceptor antagonists prazosin, phentolamine and yohimbine upon 5-methoxy-N,N-dimethyltryptamine (5-MeODMT)-induced analgesia were tested in the hot-plate, tail-flick and shock-titration tests of nociception with rats. Intrathecally injected yohimbine and phentolamine blocked or attenuated the analgesia produced by systemic administration of 5-MeODMT in all three...

The effect of chronic and acute oral or intraperitoneal treatment with the antidepressant drugs, desipramine, amitriptyline, alaproclate and iprindole, upon pain thresholds in the tail flick, hot plate and shock titration tests of nociception in saline- and 5-MeODMT-treated rats was studied. Chronic desipramine treatment increased the pre-test tail flick latencies. In the saline-treated rats,...

Two experiments were performed on Sprague-Dawley rats to study the effects of noradrenaline and 5-hydroxytryptamine depletion upon the antinociceptive effects of acute 5-methoxy-N,N-dimethyltryptamine (5-MeODMT) administration. 6-Hydroxydopamine-induced lesions following microinjections to either the locus coeruleus or the spinal cord (lumbar) abolished completely 5-MeODMT-induced analgesia in...

The acute effects of the 5-hydroxytryptamine agonist, 5-Methoxy-N,N-dimethyltryptamine (5-MeO-DMT), upon pain sensitivity, using shock titration, tail-flick and hot-plate methods, in noradrenaline- and 5-hydroxytryptamine-depleted rats were examined. Noradrenaline depletion, following the systemic administration of N-2-chloroethyl-N-ethyl-2-bromobenzylamine hydrochloride (DSP4, 2 X 50 mg/kg,...
