[Application of near-infrared spectroscopy for differential detection of neuroleptics, derivatives of benzamides].

A method is proposed for the detection of neuroleptics including benzamide derivatives, such as amisulpride, sulpiride, and tiapride with the use of spectroscopy in the near infrared region. The method may be used for the purpose of forensic medical examination and chemico-toxicological studies. Specifically, it allows three characteristics of benzamide derivatives to be identified that make possible reliable discrimination between them.
