Diabetic peripheral neuropathy (DPN) is a complication of diabetes mellitus that occurs in both type 1 and type 2 diabetics. This complication is estimated to be prevalent in approximately 50% of the diabetic population and is associated with significant morbidity and mortality. Painful DPNs affect a minority of patients with DPN but are often chronic, severe, and debilitating. Many pharmacologic agents—including but not limited to pregabalin, duloxetine, tricyclic antidepressants, abapentin, and carbamazepine—have been studied and proven effective for the treatment of pain associated with DPN. Data from these studies were extracted and evaluated to compile a list of agents that are effective in treating painful diabetic neuropathies.
