Single dose oral aceclofenac for postoperative pain in adults.

Aceclofenac is the prodrug of the non-steroidal anti-inflammatory drug (NSAID) diclofenac, widely used to treat acute and chronic pain. There are no known systematic reviews of its analgesic efficacy in acute postoperative pain. This review sought to evaluate the efficacy and safety of oral aceclofenac in acute postoperative pain, using clinical studies of patients with established pain, and with outcomes measured primarily over 6 hours using standard methods. This type of study has been used for many decades to establish that drugs have analgesic properties.
