Thiocolchicoside (Muscoril, Myoril, Neoflax) is a muscle relaxant with anti-inflammatory and analgesic effects.^[3]^[4]^[5]^[6] Its mechanism of action is unknown, but it is believed to be act via antagonism of nicotinic acetylcholine receptors (nAchRs). However, it also appears to be a competitive antagonist of GABA_A and glycine receptors.^[7]^[8] As such, it has powerful convulsant activity and should not be used in seizure-prone individuals.^[9]^[10]^[11]
