Diabetic neuropathy is common in patients with diabetes mellitus, and 7.5% of diabetics experience pain from diabetic neuropathy. Complications of diabetes mellitus are more common where control of the disease is not optimal. By improving the control of the disease, both the neuropathy and the pain it can produce may be improved. The pain of diabetic neuropathy can frequently be controlled using analgesics, antidepressants, anticonvulsants, topical capsaicin, and neuromodulation, either alone or in any combination.

Review Randomized Controlled Trial Multicenter Study Clinical Trial
Postherpetic neuralgia: role of gabapentin and other treatment modalities.
Postherpetic neuralgia (PHN) is a chronic and painful condition that may occur after a herpes zoster infection. The frequency of PHN after untreated zoster varies widely. Age is the most important risk factor for development of PHN. ⋯ Until recently, carbamazepine was the only antiepileptic drug evaluated for the treatment of PHN. Over the past few years, however, gabapentin has received increasing attention as a useful treatment for neuropathic pain. Gabapentin lacks significant drug-drug interactions and has a favorable safety profile, which makes it particularly useful for treatment of PHN.

Postherpetic neuralgia (PHN) is a separate disease entity that represents a complication of acute herpes zoster. PHN, involving aberrant somatosensory processing in the peripheral and/or central nervous system, is considered to be a chronic neuropathic pain, frequently unresponsive to all treatment modalities. Despite the clinical trial data demonstrating successful pain relief with several drug regimens, the pharmacologic management of neuropathic pain is difficult, particularly in PHN. ⋯ There is also consistent support for intravenous and topical lidocaine, intravenous ketamine, carbamazepine, and opioids. Gabapentin, a new anticonvulsant, can be considered a first-line oral medication for PHN based on the efficacy and safety results of a recently completed double-blind trial. In addition to positive effects on PHN, sleep, mood, and overall quality of life were significantly improved.

Comparative Study Clinical Trial Controlled Clinical Trial
Topical acetylsalicylic acid versus lidocaine for postherpetic neuralgia: results of a double-blind comparative clinical trial.
A double-blind comparative clinical trial was performed with topical aspirin versus lidocaine for the treatment of 40 patients with postherpetic neuralgia. The percentage improvement following topical aspirin application was 72.2 +/- 19.9 S. ⋯ D. These results suggest that the effect of topical treatment with aspirin is as good as that with lidocaine, since there was no significant difference (P = 0.778) between the two drugs in respect of pain reduction and accordingly the topical application of acetylsalicylic acid can be equally recommended.

For decades, antiepileptic drugs (AEDs) have been used to treat a variety of nonepileptic conditions such as chronic pain, psychiatric disorders, and movement disorders. As indicated by recent published reports, gabapentin, a relatively new AED, is useful for treating a wide range of neurologic and psychiatric conditions. Although its exact mechanism of action has yet to be determined, gabapentin is likely to have multiple effects. ⋯ It has also been reported effective as therapy for several psychiatric disorders, most notably bipolar disorder. In addition, review of the published literature reveals the usefulness of gabapentin in movement disorders, migraine prophylaxis, and cocaine dependence. Future clinical studies will provide further insight into the range of conditions for which gabapentin is effective.
