Abstract

PURPOSE OF REVIEW:

With the aging of the population, treatment of painful neuropathies is becoming more and more important for neurological practice. This short review highlights recent findings and current problems.

RECENT FINDINGS:

In addition to tricyclic antidepressants and gabapentin, the reliability of which is established, some drugs have more recently been demonstrated to be efficacious: major and minor opioids, pregabalin, and serotonin-noradrenaline-reuptake inhibitors. In contrast, some other drugs have yielded disappointing results: memantine, mexiletine, topiramate, and - very recently - lamotrigine. Three main questions are currently being debated. Notwithstanding their proven efficacy, should opioids be used in chronic noncancer pain? In which patients should serotonin-noradrenaline-reuptake inhibitors be preferred to tricyclic antidepressants? What is the difference between pregabalin and gabapentin? The whole field suffers from important limitations that make evidence-based medical data hard to translate in clinical practice: most clinical trials were and still are focused on two conditions only (diabetic neuropathy and postherpetic neuralgia) and studies on polytherapy are insufficient.

SUMMARY:

A large variety of drugs are being tried in the treatment of painful neuropathy. Neurologists now have a wide choice. Recent publications can help in choosing the best treatment course.
