PG - 116-23 LID - 10.1177/1470320312460899 [doi] AB - The present study was designed to investigate the potential of aliskiren, a direct renin inhibitor, in chronic constriction injury (CCI)-induced neuropathic pain in rats. Neuropathic pain was induced by placing four loose ligatures around the sciatic nerve. Acetone drop, von Frey hair, pin-prick and hot plate tests were performed to assess cold allodynia, mechanical allodynia, mechanical and heat hyperalgesia, respectively. The levels of Tumor necrosis factor-alpha (TNF-alpha) were measured in the sciatic nerve as an inflammatory marker. CCI was associated with the development of cold allodynia, mechanical allodynia, mechanical and heat hyperalgesia along with a rise in the levels of Tumor necrosis factor-alpha (TNF-alpha). Administration of aliskiren (25 or 50 mg/kg intraperitoneal (i.p.)) for 14 days in CCI-subjected rats significantly attenuated CCI-induced pain-related behavior and rise in TNF-alpha level. It may be concluded that aliskiren-mediated anti-inflammatory actions may be responsible for its beneficial effects in neuropathic pain in rats.
