Chronic neuropathic pain may be more challenging to treat than other forms of chronic pain. However, several nonopioid medications have demonstrated efficacy in patients with neuropathic pain. This chapter will summarize the evolving evidence base supporting nonopioid pharmacotherapy for neuropathic pain. Three classes of medications are consistently considered first-line treatments for neuropathic pain: certain antidepressants, including tricyclics, duloxetine, and venlafaxine; calcium channel α2δ ligands (ie, gabapentin and pregabalin); and topical lidocaine for localized, peripheral neuropathic pain. Several additional medications have been studied in neuropathic pain but have produced less favorable results. This chapter also will summarize a recommended approach to the management of patients with chronic neuropathic pain. Continuum Lifelong Learning Neurol 2009;15(5):70-83.
