Abstract:

Over several months, 14 people were admitted in 6 hospitals with severe symptoms of intoxication with psychoactive substances as a result of mass poisoning. All symptoms occurred after taking a drink that contained crushed phenazepam tablets. Samples of blood (n=10) and urine (n=6) taken from 14 sufferers for forensic, chemical and toxicological examination were analyzed using the HPLC-MS/MS method. Phenazepam was detected in the biomaterial of all 14 patients. Other psychoactive substances (baclofen, pregabalin, chlorprothixene, chlorpromazine, phenibut, tramadol, diazepam), narcotic substances and ethanol were also found in the sufferers. The phenazepam concentration in the blood was in the range of 109.75—786.50 ng/ml, in the urine — 8.97—101.28 ng/ml. The pharmacokinetic and toxicokinetic characteristics of toxicants as well as additional factors characterizing the phenotype of the sufferer in addition to drug’s content in the biological material must be taken into account to determine the toxicity level of phenazepam against the background of combined action with other psychoactive substances.
