Thiocolchicoside (Muscoril, Myoril, Neoflax) is a muscle relaxant with anti-inflammatory and analgesic effects.^[3]^[4]^[5]^[6] It acts as a competitive GABA_A receptor antagonist and also inhibits glycine receptors with similar potency and nicotinic acetylcholine receptors to a much lesser extent.^[7]^[8] It has powerful convulsant activity and should not be used in seizure-prone individuals.^[9]^[10]^[11]

[edit] Side effects

Side effect of skeletal muscle relaxants may include: sedation, drowsiness, blurred or double vision, constipation or diarrhea, dizziness and drowsiness, nervousness and confusion, dry mouth, dyspepsia (chronic or recurrent pain in the upper abdomen, upper abdominal fullness, and feeling full earlier than expected when eating), fatigue, headache, heartburn, hiccups and nausea, insomnia, stomach cramps, trembling, vomiting, and weakness; and possible dependence following long-term use.
