Clomethiazole (also called chlormethiazole) is a sedative and hypnotic originally developed by Hoffmann-La Roche in the 1930s.〔 〕 The drug is used in treating and preventing symptoms of acute alcohol withdrawal. It is structurally related to thiamine (vitamin B1), but acts like a sedative, hypnotic, muscle relaxant and anticonvulsant. It is also used for the management of agitation, restlessness, short-term insomnia and Parkinson's disease in the elderly. In the UK, it is sold under the brand Heminevrin (AstraZeneca Pharmaceuticals). Another brand name includes Nevrin in Romania, Distraneurin in Germany and Distraneurine in Spain. The drug is marketed either as a free base in an oily suspension containing 192 mg in capsule form, or as clomethiazole edisylate syrup. == Pharmacology == Chlomethiazole acts as a positive allosteric modulator at the barbiturate/picrotoxin site of the GABAA receptor. It works to enhance the action of the neurotransmitter GABA at this receptor. GABA is the major inhibitory neurotransmitter in the brain and produces anxiolytic, anticonvulsant, sedative, and hypnotic effects. Chlomethiazole appears to also have another mechanism of action mediating some of its hypothermic and neuroprotective effects.
