ABSTRACT
Abstract Neuropathic pain is generally characterised by an abnormal sensation (dysesthesia), an increased response to painful stimuli (hyperalgesia), and pain in response to a stimulus that does not normally provoke pain (allodynia). The present study was designed to investigate the effect of trazodone (5mg/kg and 10mg/kg) on peripheral neuropathic pain induced by partial sciatic nerve ligation in rats. Mechanical hyperalgesia, cold allodynia and thermal hyperalgesia were assessed by performing the pinprick, acetone, and hot plate tests, respectively. Biochemically, lipid peroxidation level and total calcium levels were measured. However, trazodone administration (5 and 10 mg/ kg i.p.) for 21days significantly diminished partial sciatic nerve ligation-induced neuropathic pain along with areduction in oxidative stress and calcium levels. The results of the present study suggest that trazodone is effective in attenuating partial sciatic nerve ligation-inducedpainful neuropathic states, which may be attributed to decreased oxidative stress and calcium levels.

A utilização de medicações psicoativas vem crescendo ao longo dos anos, sendo essencial o conhecimento de seus efeitos colaterais e interações medicamentosas. O desenvolvimento de distúrbios de movimento associados ao uso dessas substâncias é uma situação bastante desconfortável para o paciente, sendo essencial o diagnóstico adequado mediante forte suspeição. Relata-se o caso de um paciente que desenvolveu sintomas de parkinsonismo durante tratamento de hérnia discal lombar na vigência do uso de trazodona. É dada ênfase aos mecanismos de produção desse fenômeno e à sua condução clínica...
The use of psychoactive medications has been growing over years, being essential the knowledge of its side effects and interactions. The development of movement disturbances is a very uncomfortable situation for the patient, requiring a high suspicion for adequate diagnosis. A case of a patient who presented symptoms of Parkinsonism during use of Trazodone in the treatment of lumbar disc herniation is reported. Emphasis is given to the biological mechanisms of this phenomenon and its clinical conduction...

Comunicamos la aparición de movimientos anormales inducidos por dos fármacos de común uso en el adulto: trazodona y veralipride. El primer paciente desarrolla un parkinsonismo luego de una semana de usar Trazodona: la sintomatología se revierte al cabo de algunas semanas de suspendida la droga. El segundo paciente se presenta con una distonía tardía que comprometió extremidades inferiores, pared abdominal y región oro-mandibular luego de 2 meses de usar Veralipride: la sintomatología desaparece luego de 1 mes de suspendida la droga. Esta comunicación enfatiza la necesidad de mayor reconocimiento de este tipo de reacciones adversas de estos fármacos de común uso en nuestro medio.
We report the occurrence of abnormal movements induced by two drugs of common use in middle-aged patients: trazodone and veralipride. The first patient developed a akinetic-rigid syndrome after 1 week of using trazodone; the parkinsonism subsided completely a few weeks after drug withdrawal. The second patient presented with a tardive dystonia involved lower limbs, abdominal wall and face after two months of taking veralipride, the movements also gradually disappeared after stopping veralipride. Our report emphasizes the need for more awareness by clinicians of these secondary effects which can severely affect patients.
