Clopenthixol (Sordinol), also known as clopentixol, is a typical antipsychotic drug of the thioxanthene class. It was introduced by Lundbeck in 1961.[1]

Clopenthixol is a racemic mixture of cis and trans isomers. Zuclopenthixol, the pure cis isomer, was later introduced by Lundbeck in 1962,[2] and has been much more widely used. Both drugs are equally effective as antipsychotics and have similar adverse effect profiles, but clopenthixol is half as active on a milligram-to-milligram basis and appears to produce more sedation in comparison.[3]

Clopenthixol is not approved for use in the United States.
