Skeletal Muscle Relaxants

Skeletal muscle relaxants are a class of medications used to treat muscle spasms, spasticity, and musculoskeletal pain. They include both centrally acting agents (cyclobenzaprine, methocarbamol) and peripherally acting agents (dantrolene).

Mechanism of Action

Centrally acting muscle relaxants work by depressing the central nervous system, reducing nerve signals that cause muscle contractions. They act on the brain stem and spinal cord to interrupt the pain-spasm-pain cycle. Peripherally acting agents like dantrolene work directly on muscle fibers by inhibiting calcium release from the sarcoplasmic reticulum.
