PURPOSE: The objective of this study was to investigate the analgesic effect of a collagen conduit (Neuragen, Integra LifeSciences Corp, Plainsboro, NJ) using duloxetine (Cymbalta, Lilly, Indianapolis, IN) with or without pregabalin (Lyrica, Pfizer, NY) on pain induced by partial sciatic nerve transection in a rat model.
MATERIAL AND METHODS: Adult male Sprague-Dawley rats were divided into 5 groups (n = 10 per group): group 1, nerve damage with no treatment; group 2, nerve damage treated with the application of a collagen conduit and saline; group 3, nerve damage treated with the application of a collagen conduit and duloxetine; group 4, nerve damage treated with the application of a collagen conduit and pregabalin; and group 5, nerve damage treated with the application of a collagen conduit and pregabalin plus duloxetine. Pain levels were evaluated by responses to mechanical and thermal stimuli at baseline before and 3 and 7 days after surgery. Interleukin (IL)-6, IL-10, and tumor necrosis factor (TNF) levels were evaluated in blood, sciatic nerve, and dorsal root ganglion samples collected 7 days after surgery.
RESULTS: The group treated with the collagen conduit and pregabalin exhibited markedly less pain 7 days postoperatively in response to mechanical and thermal stimuli compared with the other groups. IL-10 levels were considerably increased in the group treated with pregabalin. The groups treated with a collagen conduit and duloxetine and a combination of pregabalin and duloxetine also exhibited markedly less pain in response to mechanical and thermal stimuli 7 days after surgery compared with the group that had only nerve injury. The decrease in pain using duloxetine was not as robust but was associated with a decrease of TNF-α. The combination of pregabalin and duloxetine resulted in a substantial decrease in IL-6.
CONCLUSION: Using a collagen conduit and duloxetine, pregabalin, and their combination helped alleviate neuropathic pain. The mechanism of action might be associated, at least in part, to cytokines.
