Mydocalm is a centrally acting muscle relaxant that acts at the reticular formation in the brainstem by blocking voltage-gated sodium and calcium channels. It is used for treating painful musculoskeletal disorders with hypermyotonia and decreased motility, especially those resulting from spinal cord injuries, osteoporosis, arthritis, and spasticity.
