Randomized Controlled TrialA pilot study of the effect of diclofenac with B vitamins for the treatment of acute pain following lower-limb fracture and surgery.
The aim of this pilot study was to compare the efficacy and tolerability of the non-steroidal anti-inflammatory drug (NSAID), diclofenac (2-(2,6-dichloranilino) phenylacetic acid), for treatment of acute pain originated by lower-limb fracture and surgery, with that of diclofenac plus B vitamins. This clinical trial was single-center, prospective randomized and double-blinded. After giving informed consent, patients with lower-limb closed fractures rated their pain on a 10-cm visual analog scale (VAS). ⋯ The subjects' assessments of limb pain on the visual analog scale showed a significant reduction from baseline values regardless of the treatment group when surveyed at 12, 24, 36 and 48 hr post operation. All treatments showed a similar profile in pain reduction. There were reports of pain in the administration site, but in general, all the regimens were well tolerated.
