Features of forensic chemical analysis non-steroidal anti-inflammatory drugs in the Krasnoyarsk Regional Bureau of Forensic Medicine for the period 2016-2018 years

Relevance. The use of non-steroidal anti-inflammatory drugs (NSAIDs) is not limited to medical indications. Drugs are often used to relieve pain in drug addiction, so they are often found during forensic analysis along with psychoactive substances. The identification and measurement of the concentration of any toxicants is important for establishing a causal relationship between their use and harm to health or death. Purposes of the work: to identify the use of NSAIDs by different groups of consumers; determination of the possibility of using these drugs as indirect markers of the use of controlled substances; establishing a correlation between the joint detection of NSAIDs and controlled substances; comparison of detected concentrations of substances with therapeutic, toxic, lethal concentrations. The research material was the results of the work of the forensic chemical department of the Krasnoyarsk Bureau of Forensic Medical Examination for 2016-2018. Biological material research methods included liquid-liquid extraction of compounds from objects, gas chromatography with mass spectral detection after derivatization. The results of forensic chemical studies were processed and interpreted using factor, regression, and correlation analysis methods. Results. Data were obtained on the age-sex characteristics of NSAIDs consumers, a positive correlation between the use of NSAIDs and controlled substances, the range of concentrations of NSAIDs in cadaveric blood was determined. Conclusions. An increase in the detection of NSAIDs during forensic chemical studies was revealed. The main consumers of this group of medicines are persons aged 31 to 45 years; the number of male consumers prevails over women. Detection of NSAIDs in biological fluids of cadavers and a strong positive correlation may serve as markers of possible intravital use of controlled substances. Excess toxic concentrations of NSAIDs in cadaveric blood was recorded in 0.33% of cases, typical only for ibuprofen and ketorolac.Key words: forensic chemical analysis, non-steroidal anti-inflammatory drugs, controlled substances, use marker, correlation.
