Cyclobenzaprine is a muscle relaxant most commonly prescribed to relieve muscle spasms resulting from injuries such as sprains, strains, or pulls. In conjunction with an overall health plan, rest and physical therapy, Cyclobenzaprine provides relief of muscular stiffness and pain.
Specifically, cyclobenzaprine relieves muscle spasm when the spasm is due to local problems (that is, problems originating in the muscle itself and not in the nerves controlling the muscles). Cyclobenzaprine has no effect on muscle function. Cyclobenzaprine seems to accomplish its beneficial effect through a complex mechanism within the nervous system, probably in the brainstem.
