Thiocolchicoside is a small molecule muscle relaxant and anti-inflammatory agent, shown to function as a competitive gabaa (gamma-aminobutyric acid type a) receptor antagonist. Thiocolchicoside is also shown to inhibit strychnine-sensitive glyr (glycine receptors)with lower potency than gabaa, and to inhibit human achr (nicotinic acetylcholine receptors) with very low relative affinity.
