Gabapentin is a novel anticonvulsant that may be of value for the relief of clinical pain. To determine whether gabapentin is antinociceptive after spinal administration, the drug was given via an intrathecal catheter in doses from 6 to 200 micrograms/rat 10 min prior to intraplantar formalin. Five percent formalin injected subcutaneously in the right hind(More)
We determined whether the i.t. administration of an 18-mer phosphodiester antisense oligodeoxynucleotide (ODN) that reduces the expression of the rat NMDAR1 subunit of the N-methyl-d-aspartate (NMDA) receptor would affect nociceptive behaviors and prevent the development of morphine tolerance. Rats received 5 microl of i.t. saline, 30 nM antisense, or(More)
N-methyl-D-aspartate (NMDA) receptor antagonists may be of value in the management of hyperalgesia. LY235959, a competitive NMDA receptor antagonist, at doses of 0.001 and 0.003 nmol, intrathecally (i.t.) blocked the hyperalgesia induced by 11.1 nmol of NMDA in rats prepared with a chronic i.t. cannula. However, LY235959 does not block the hyperalgesia(More)
