    Flupentixol has been used for a long time in Russia in psychiatric practice; however, there are cases of its overdose and poisoning with it. In the literature, there are no systematic studies to identify flupenthixol in the diagnosis of acute poisoning. The purpose of the work is to analyze the distribution of flupenthixol in the internal organs of laboratory animals in acute poisoning. The studies were carried out on Wistar rats of both sexes. Sample preparation and isolation of flupenthixol from model samples and internal organs of laboratory animals was carried out according to proposed methods. To detect flupenthixol in extracts the TLC was used. HPLC and liquid mass spectrometry were used for confirmatory analysis and quantitative determination of flupenthixol in the extracts. Amethod was developed for the detection of flupenthixol in extracts from the internal organs of laboratory animals using the TLC method. HPLC/MS/MS was used as a confirmatory method for detecting flupenthixol in extracts from internal organs of laboratory animals. In all mass spectra of extracts from internal organs, a pronounced molecular ion of flupenthixol was present. In the mass spectrum of kidney extraction at 30 minutes a molecular ion of the metabolite (m/z 629.13), corresponding to flupentixolglucuronide was detected. After acute poisoning of laboratory animals, the flupenthixol was found in the maximum amount in the liver, spleen and brain, in smaller amounts in the stomach, intestines with contents and kidneys.
