Cyclobenzaprine may be used to relieve muscle spasms.
Cyclobenzaprine relaxes muscles by reducing muscle hyperactivity via gamma and alpha motor systems (these are nerve fibers that directly connect with skeletal muscle and are responsible for muscle contraction). Cyclobenzaprine acts primarily through the brain stem rather than the spinal cord and does not act directly on skeletal muscle.
Cyclobenzaprine will not reduce muscle spasms due to central nervous system (CNS) disease, such as cerebral palsy.
Cyclobenzaprine belongs to a class of drugs known as muscle relaxants.
