Abstract
Na presente revisão de literatura foram relacionados trabalhos experimentais e clínicos dos últimos 15 anos referentes aos efeitos dos antiinflamatórios não-esteroidais (AINEs) convencionais e seletivos para COX-2 sobre a formação óssea reparacional. A maioria dos trabalhos mostra que os AINEs convencionais podem atrasar o reparo de fratura de ossos longos e a fusão espinhal, em animais, e interferir negativamente com a taxa de fusão espinhal, em humanos. Apesar da importância comprovada da prostaglandina E2, sintetizada por osteoblastos sob estímulo da enzima ciclooxigenase-2 (COX-2), no controle da formação óssea, os resultados experimentais acerca dos prováveis efeitos inibitórios dos AINEs seletivos sobre o reparo ósseo além de raros são ainda controversos e não há comprovação de que eles interferem com a neoformação óssea reparacional em humanos.
In the present literature review, experimental and clinical studies of the last 15 years concerning the effects of conventional and COX-2 selective non-steroidal anti-inflammatory drugs (NSAIDs) on bone healing were reported. Most of the data pertaining to conventional NSAIDs have shown to cause delayed fracture healing and impairment of spinal fusion in animal studies, as well as a negative interference on spinal fusion rate in human beings. In spite of the established importance of prostaglandin E2, synthesized by osteoblasts under COX-2 stimulation, in controlling bone formation, the results regarding the potential inhibitory effects of selective NSAIDs on experimental bone healing are still controversial and there is no clinical data to confirm that they interfere negatively with repairing bone formation.
