Effect of Ceftiofur on Hyperalgesia and Allodynia in a Rat Neuropathic Pain Model: The Role of Immune Processes.
Inflammatory and immune mechanisms play important roles in the pathogenesis of neuropathic pain. Ceftiofur, a third-generation cephalosporin, has anti-inflammatory effects by inhibiting tumor necrosis factor (TNF)-α, interleukin (IL)-1β, nuclear factor (NF)-κB, and mitogen-activated protein kinase (MAPK) signaling. This study aimed to investigate the effect of ceftiofur on hyperalgesia and allodynia in neuropathic rats and to define the possible contribution of immune mechanisms to this effect. ⋯ Ceftiofur has anti-inflammatory effects by decreasing iNOS, IL-1β, and p38 MAPK expression in lumbar spinal cord, and treatment of neuropathic rats with repeated doses of ceftiofur for 14 days results in antihyperalgesic effects.
