Conditions
Keywords
Cervical strain, whiplash, ibuprofen, cyclobenzaprine
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.
Interventions
5 mg orally every 8 hours as needed
Ibuprofen 400 mg every 8 hours as needed
