Electroacupuncture Potentiates the Antiallodynic Effect of Intrathecal Neostigmine in a Rat Model of Neuropathic Pain

抄録

This study was performed to examine whether electroacupuncture potentiates the neostigmine-induced antiallodynia in neuropathic pain rats. Although intrathecal neostigmine (0.05, 0.1 and 0.3 μg) dose dependently relieved cold allodynia, 0.3 μg neostigmine caused side effects. Whereas, co-application of 0.1 μg neostigmine and electroacupuncture produced potent antiallodynia, which was parallel to the effect of 0.3 μg neostigmine, without side effects. These results indicate that electroacupuncture can enhance the antiallodynic action of intrathecal neostigmine.
