Mechanism of Action
Cyclobenzaprine, a centrally-acting skeletal muscle relaxant, is structurally related to tricyclic antidepressants, thus they share similar properties. It acts on the brain stem, decreasing tonic-somatic motor activities influencing both the ? and ? motor systems. It is used as an adjunct in the symptomatic treatment of painful muscle spasms associated with musculoskeletal conditions.
