Thiocolchicoside is a muscle relaxant with anti-inflammatory and analgesic properties, marketed under brand names such as Muscoril, Myoril, and Neoflax. It is commonly prescribed to treat painful muscle spasms, especially those associated with musculoskeletal conditions, low back pain, or neurological disorders.
While its exact mechanism of action is not fully understood, Thiocolchicoside is believed to act via antagonism of nicotinic acetylcholine receptors (nAchRs) in the central nervous system, which helps reduce muscle stiffness and pain perception.
It is available in various dosage forms, including oral tablets, topical gels, and intramuscular injections.
