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

Clopenthixol is a mixture of cis and trans isomers. Zuclopenthixol, the pure cis isomer, was later introduced by Lundbeck in 1962, 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.
