Comparison of Ibuprofen, Cyclobenzaprine, or Both for Acute Cervical Strain: A Randomized Clinical Trial

Overview[ - collapse ][ - ]

Purpose The purpose of this study is to see whether the combination of a muscle relaxant and anti-inflammatory drug is more effective at relieving pain in patients with neck strains or whiplash than either of the two medications alone.

Brief Summary
The purpose of this study is to see whether the combination of a muscle relaxant and
anti-inflammatory drug is more effective at relieving pain in patients with neck strains or
whiplash than either of the two medications alone.
Detailed Description
Muscle relaxants have been used extensively for neck and back pain since muscle spasm is
thought to play a role in the cycle of pain and spasm. However, prior studies have
conflicting results regarding their additive effect when given in addition to analgesics
such as the NSAIDs. Because they have the potential to lead to adverse events their
efficacy should be clearly demonstrated before their routine use.
