Anti-Inflammatory Effect of Local Anaesthetic Ropivacaine in Lipopolysaccharide-Stimulated RAW264.7 Macrophages

The present manuscript intended to investigate the anti-inflammatory effect of ropivacaine on lipopolysaccharide-induced inflammation in RAW 264.7 macrophages. Results suggested that ropivacaine causes significant inhibition of generation of nitric oxide (NO), prostaglandin E2, tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β, as well as expression of their synthesizing enzymes, inducible NO synthase, and cyclooxygenase-2. Moreover, ropivacaine causes inhibition of mitogen-activated protein kinases as well as nuclear factor-kappa B signaling pathway and apoptosis in RAW 264.7 cells. Based on the results, it has been suggested that ropivacaine showed beneficial effect against inflammation.
