Cas no 533-45-9 (clomethiazole)

Clomethiazole (also known as chlormethiazole) is a sedative and hypnotic agent primarily used in the treatment of acute alcohol withdrawal symptoms and severe insomnia. Its chemical structure is based on a thiazole ring, which contributes to its pharmacological activity as a GABA receptor modulator. The compound exhibits rapid onset of action and effective calming properties, making it suitable for managing agitation and delirium in clinical settings. Clomethiazole is available in oral and intravenous formulations, allowing for flexible dosing based on patient needs. Its metabolism occurs primarily in the liver, with a relatively short half-life, reducing the risk of prolonged sedation. Careful monitoring is advised due to potential respiratory depression at higher doses.
