Painful Peripheral Neuropathy.
Treatment of neuropathic pain is the primary focus of management for many patients with painful peripheral neuropathies. Neuropathic pain is a common feature of many peripheral neuropathies including those associated with diabetes, uremia, HIV infection, and alcohol abuse. Pain is also present in the majority of patients with idiopathic sensory and sensorimotor polyneuropathies. A growing number of pharmacologic agents are available for the treatment of neuropathic pain. The medications that have undergone the most rigorous study are the tricyclic antidepressants and anticonvulsants. These two families of medications are widely used and represent first-line agents in the management of neuropathic pain. Pain management should begin with a concerted effort to identify the etiology of the neuropathy, as directed therapy may help alleviate the symptoms. When initiating pharmacotherapy for neuropathic pain, one must individualize treatment and choose an agent that is likely to be tolerated, as adverse events are not uncommon for some of the medications. Treatment of neuropathic pain remains challenging, with considerable variability in an individual's response to the various agents and even to different drugs in the same class. However, monotherapy with a well-chosen agent or rational polypharmacy that combines medications with different mechanisms of action will benefit a majority of patients with neuropathic pain.
