Chlormethiazole positively modulates the gamma-aminobutyric acid (GABA)(A) receptor complex and is primarily used to treat certain life-threatening neurological events (e.g., refractory seizures and ethanol withdrawal syndrome). On account of several experimental and clinical studies reporting effectiveness against the toxic effects

Clomethiazole is a gamma-aminobutyric acid (GABA)-mimetic agent with anticonvulsant, sedative and neuroprotective properties. The pharmacological actions of clomethiazole that underlie its functional profile have not been fully explored, but are known to result from an interaction with the GABA(A) receptor.
