Chemical compound
Trional (Methylsulfonal) is a sedative-hypnotic[1] and anesthetic drug with GABAergic actions[citation needed]. It has similar effects to sulfonal, except it is faster acting.[2]
History
Trional was prepared and introduced by Eugen Baumann and Alfred Kast in 1888.[3]
Appeared in Agatha Christie's "Murder on the Orient Express", "And Then There Were None" and other novels such as John Bude’s “The Lake District Murder” as a sleep inducing sedative, and in In Search of Lost Time (Sodom and Gomorrah) by Marcel Proust as a hypnotic. Sax Rohmer also references trional in his novel Dope.
