WHAT IS THE MECHANISM OF ACTION?

 Chlorzoxazone is a centrally-acting drug for painful musculoskeletal conditions. It acts primarily at spinal cord and subcortical areas of the brain and inhibits the mechanism responsible for spasm of skeletal muscle. This results in reduction of the skeletal muscle spasm with relief of pain and thus increases movement of the involved muscles.

 It inhibits the release of histamine and slow-reacting substance of anaphylaxis (SRS-A), both of which are responsible for allergic reactions. It also reduces the release of inflammatory leukotrienes. It causes inhibition of nerve signals and act as muscle relaxant by its feature of inhibiting calcium and potassium influx.
