Anticonvulsant drugs, especially carbamazepine, are the treatment of choice for glossopharyngeal neuralgia. If no clinical response is obtained, surgical treatment, including nerve section or decompression, may be required. ⋯ Response was poor in patients who had undergone surgical nerve decompression. Gabapentin was concluded to be an effective therapeutic option for neuralgia of the IXth cranial nerve before surgery.

Pudendal neuralgia caused by nerve compression may be improved by surgical decompression of the pudendal nerve. This study was undertaken to determine if clinical symptoms, electrophysiological investigations, and the efficacy of preoperative pudendal nerve blocks could be used to predict the efficacy of surgery. ⋯ This preliminary study suggests that complete disappearance of pain for at least two weeks after a nerve block repeated twice before surgery may be the best criterion to predict success. Based on this criterion, surgery would have been performed in four patients in this study, of whom three would have been cured.

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.

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.

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.
