Abstract

BACKGROUND: Many clinical pain states that are difficult to treat share a common feature of sensitization of nociceptive pathways. Drugs that could normalize hyperexcitable neural activity (e.g., antiepileptic drugs) may be useful in relieving these pain states. Eslicarbazepine acetate (ESL) is a novel antiepileptic drug derived from carbamazepine/oxcarbazepine with a more favorable metabolic profile and potentially better tolerability. We examined the efficacy of ESL in models of inflammatory and neuropathic pain and the potential mechanism involved in its action. METHODS: The antinociceptive effects of ESL were assessed in mice models of trigeminal (orofacial formalin test), neuropathic (streptozotocin-induced diabetic neuropathy model), and visceral pain (writhing test). The influence of 5-HT1B/1D serotonin receptor (GR 127935) and CB1 (AM251) and CB2 cannabinoid receptor (AM630) antagonists on the antinociceptive effect of ESL was tested in the model of trigeminal pain. RESULTS: ESL exhibited significant and dose-dependent antinociceptive effects in the second phase of the orofacial formalin test (P
