Muscle relaxants are agents that reduce tension in muscles.
Centrally acting muscle relaxants work by reducing the tone of skeletal muscle causing muscles to relax. These are generally used to relieve skeletal muscle spasms due to spastic conditions, and can be used to relieve musculoskeletal pain.
Other muscle relaxants work peripherally at neuromuscular junctions and block the transmission of impulses. These drugs do not have any effect on the central nervous system. They are used to relax voluntary muscles during surgery and are only used as an adjunct to anesthesia.
