Centrally acting skeletal muscle relaxants and associated drugs.

A review of available studies supports a role for muscle relaxants in the treatment of painful musculoskeletal disorders. The utility of these drugs is limited by sedation and other side effects, as well as by the potential for abuse and dependency. Other drugs can also be used in the treatment of muscle spasm, specifically diazepam, baclofen, dantrolene sodium, and quinine sulfate. The pharmacology of the muscle relaxants and these other agents is discussed and practical suggestions for use are offered.
