Ethinamate (Valamin, Valmid) is a short-acting carbamate-derivative sedative-hypnotic medication used to treat insomnia. Regular use leads to drug tolerance, and it is usually not effective for more than 7 days. Prolonged use can lead to dependency.

Ethinamate has been replaced by other medicines (particularly benzodiazepines), and it is not available in the Netherlands, the United States or Canada.

Chemistry[edit]

Ethinamate (1-ethynylcyclohexanone carbamate) is synthesized by combining acetylene with cyclohexanone and then transforming the resulting carbinol into a carbamate by the subsequent reaction with phosgene, and later with ammonia. Some lithium metal or similar is used to make the acetylene react with the cyclohexanone in the first step.[1][2]
