Investigation of the Analgesic Properties L-759,633 and SER 601 in Experimental Neuropathic Pain Model in Rats and their Comparison with Pregabalin

Abstract

Despite the fact that narcotics and NSAIDs are the mainstays of nociceptive pain care, only a small proportion of neuropathic pain patients benefit from them. Cannabinoid agents could be a viable alternative to opioids in the management of chronic pain. The goal of our investigation was to assess the analgesic efficacy of SER 601 and L-759,633, cannabinoid receptor 2 (CB2) agonists, at various doses in a model of neuropathic pain generated in rat. The analgesic effect of CB2 agonists L-759,633 and SER 601 at various doses in a rat model of neuropathic pain created by partial sciatic nerve ligation was examined by the hot plate method. Furthermore, a comparison of analgesic effects of both drugs with pregabalin is also conducted. The two substances demonstrated a dose-dependent analgesic effect in this model. The analgesic response of SER601 and L-759,633 in the neuropathic pain model was higher compared to that of pregabalin. All in all, our data suggest that SER601 and L-759,633 may offer a beneficial treatment option for neuropathic pain in future.
