Abstract:
We report a clinical multicentre experience with antidepressant agents (trazodone and amitriptyline) in the treatment of chronic pain due to deafferentation. Forty five patients were admitted to the study; most of them with oncological peripheral nerve lesions. Almost all of them were already being treated with NSAID in association with weak or strong opioids. A random double blind study was performed: 23 patients were treated with trazodone, 22 with amitriptyline. In the assessment of results, pain intensity, hours of sleep, hours standing and lying, side effects, mood, anxiety and weakness were all taken into consideration. The therapeutic analgesic efficacy of the two drugs proved to be similar.
