[Guidelines for the clinical management of neuropathic pain (II)].
BACKGROUND
Up to 5% of the population suffers from neuropathic pain (NP). A bibliographical search in several databases revealed that, to date, there are no protocols to guide physicians who are not specialists in pain that enable them to treat NP and thus improve patients' quality of life.


OBJECTIVE
The aim of this study is to provide Spanish-speaking physicians who are not specialists in pain with a set of guidelines for the treatment of NP. A bibliographical search was performed in order to base the results and conclusions on the evidence-based medicine methodology.


METHODS
First, we review the most effective clinical and paraclinical methods for diagnosing NP, and the LANSS pain scale is reported as the most appropriate method of clinically evaluating NP. The anatomical paths and the physiology of pain are then described and we review the molecular variables involved. Finally, we point out the current therapeutic options and propose an algorithm for the treatment of NP.


CONCLUSIONS
There is no specific set of guidelines for the treatment of NP. At the present time, the keystone of NP treatment consists in the use of antidepressant and anticonvulsive drugs. There is a need for further clinical trials to prove the effectiveness of using combined medication.
