How it works

Cyclobenzaprine can help with muscle spasms.

Cyclobenzaprine relaxes muscles by inhibiting hyperactivity in the gamma and alpha motor systems (these are nerve fibers that directly connect with skeletal muscle and are responsible for muscle contraction). Cyclobenzaprine acts primarily on the brain stem rather than the spinal cord, and it has no direct effect on skeletal muscle.

Cyclobenzaprine has no effect on muscle spasms caused by central nervous system (CNS) disease, such as cerebral palsy.

Cyclobenzaprine belongs to the muscle relaxant class of drugs.
