Complete Prevention but Stimulus-dependent Reversion of Morphine Tolerance by the Glycine/NMDA Receptor Antagonist (+)-HA966 in Neuropathic Rats

The ability of the glycine/ N-methyl-D-aspartate receptor antagonist (+)-HA966 to modify morphine tolerance in a rat model of neuropathic pain was studied to prevent the development of tolerance and reverse established morphine tolerance.

The antimigraine 5‐HT1B/1D receptor agonists, sumatriptan, zolmitriptan and dihydroergotamine, attenuate pain‐related behaviour in a rat model of trigeminal neuropathic pain

The rationale for exploring the clinical efficacy of brain penetrant 5‐HT1B/1D receptor agonists as analgesics to reduce certain types of trigeminal neuropathic pain in humans is supported.

Additive Effect of Combined Application of Magnesium and MK-801 on Analgesic Action of Morphine

If magnesium sulphate and MK-801 were applied concomitantly, a clear additive effect on the analgesic action of morphine occurred in both models of pain.

The findings suggest that combined administration of antagonists, acting at the glycine site of the NMDA receptor complex and morphine may be a promising approach in the treatment of neuropathic and acute pain.

N-methyl-D-aspartate receptor antagonists potentiate morphine's antinociceptive effect in the rat.

It is suggested that blockade of NMDA receptors enhances the antinociceptive effect of morphine and NMDA antagonists may improve the analgesic efficacy of morphine in the clinic.

NMDA receptor antagonists: interactions with opioids

The N‐methyl‐D‐aspartate (NMDA) receptor for glutamate has been implicated in the generation and maintenance of central (spinal) states of hypersensitivity and the ability of opioids to act presynap‐tically on C‐fibre terminals to reduce transmitter release produces synergistic inhibitions with postsynaptically acting NMDA receptor antagonists.
