Standardization of the analytical procedure based on deep eutectic solvent for the extraction and measurement of tricyclic antidepressants drugs in post-mortem blood samples. J Pharm Biomed Anal 2024; 238:115811. [PMID: 37879218 DOI: 10.1016/j.jpba.2023.115811] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/15/2023] [Accepted: 10/20/2023] [Indexed: 10/27/2023]
Abstract
Measuring drugs in post-mortem blood samples is one of the most important challenges in forensic medicine. The development of sensitive analytical techniques for the measurement of drugs in biological samples is of great use in forensic medicine. In this research an easy, safe and environmental friendly vortex-assisted liquid phase microextraction (VA-LPME) based on deep eutectic solvent (DES) followed by high performance liquid chromatography-ultraviolet detector (HPLC-UV) was developed for the extraction, preconcentration and analysis of tricyclic antidepressants drugs (TCAs) in post-mortem blood samples. DES synthesized from thymol as hydrogen bond acceptor (HBA) and ethylene glycol (EG) as hydrogen bond donor (HBD) with a molar ratio of 2:1 was used as an extractant. After adding DES to the sample solution, the resulting mixture was vortexed in order to increase the contact surface and increase the extraction efficiency. Next, phase separation was done using centrifugation. Some effective parameters on the extraction were studied and optimized. Under the optimum conditions, intra- and inter-day %RSDs of the method based on 7 replicate measurements of 100 μg L-1 of TCAs in blood samples were in the range of 2.4-5.1 and 3.7-6.8 %, respectively. The analytical performance of the method showed linearity over the concentration of 3-500 μg L-1 with the detection limits ranging from 1.0-2.0 μg L-1. The trueness of the method was confirmed by spiking different concentrations of TCAs in real blood samples and obtaining relative recoveries in the range of 91.2-108 %.

Cork sheet as an efficient biosorbent for forensic toxicology: Application to vitreous humor analysis. J Anal Toxicol 2023; 47:580-587. [PMID: 37506044 DOI: 10.1093/jat/bkad045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Revised: 07/05/2023] [Accepted: 06/20/2023] [Indexed: 07/30/2023] Open
Abstract
There is an increasing number of people affected worldwide by mental health disorders, such as depression and anxiety. One of the main courses of treatment, along with psychotherapy, is the use of psychoactive medications, like antidepressants and benzodiazepines. Also, the unprescribed use of these substances is a concerning public health issue. Hence, the analysis of psychotropic medications is mandatory in postmortem toxicology and various biological samples can be used for this detection, among them the vitreous humor (VH) stands out. Also, there is a demand for more sustainable and more efficient extraction methodologies according to green chemistry. An example is solid phase microextraction techniques (SPME), which use a solid sorbent and small solvent amounts. Biosorbents are substances of natural origin with sorptive properties, and they have been successfully used in SPME in environmental toxicology for water analysis, mainly. This study aimed to develop a sustainable, fast, cheap and simple SPME methodology using cork sheet strips as a biosorbent, to extract antidepressants, benzodiazepines and others from VH samples by liquid chromatography coupled to tandem mass spectrometry. The extraction was conducted in a 96-well plate using 200 µL of VH and optimization of relevant parameters for extraction was performed. For solvent optimization, two simplex-centroid experiments were planned for extraction and desorption and to evaluate time and pH, a Doehlert design experiment was performed. The analytical method for the determination and quantification of 17 substances was validated. The quantification limits were 5 ng/mL for all analytes and the calibration curves were linear between 5 and 30 ng/mL. This study was able to develop an efficient, cheap, simple and fast microextraction method for 17 analytes in VH, using strips of cork sheet for extraction and a 96-well plate as a container. Furthermore, this approach system could be automated for routine toxicology laboratories.

Abstract
Depression is one of the most prevalent but severe of mental disorders, affecting thousands of individuals across the globe. Depression, in its most extreme form, may result in self-harm and an increased likelihood of suicide. Antidepressant drugs are first-line medications to treat mental disorders. Unfortunately, these medications are also prescribed for other in- and off-label conditions, such as deficit/hyperactivity disorders, attention disorders, migraine, smoking cessation, eating disorders, fibromyalgia, pain, and insomnia. This results in an increase in the use of antidepressant medications, leading to clinical and forensic overdose cases that could be either accidental or deliberate. The findings revealed that people who used antidepressants had a 33% greater chance of dying sooner than expected, compared to those who did not take the medications. Analytical techniques for precisely identifying and detecting antidepressants and their metabolic products in a variety of biological matrices are greatly needed to be developed and made available. Hence, this study attempts to discuss various analytical techniques used to identify and determine antidepressants in various biological matrices, which include urine, blood, oral fluid (saliva), and tissues, which are commonly encountered in clinical and forensic science laboratories.

Abstract
Antidepressants are an important class of drugs to treat various types of depression. The determination of antidepressants is crucial in biological samples to control adverse effects in humans and study pharmacokinetics and bioavailability. Direct measurement of antidepressants in biological and water samples is a considerable challenge for analysts due to their low concentration, the high matrix effects of real samples, and the presence of metabolites of these drugs in biological samples. The challenge leads to using sample preparation processes as a critical step in determining antidepressants. Extraction and microextraction procedures have been widely utilized as sample preparation procedures for these drugs. The purposes of extraction or microextraction methods for antidepressant medications are to preconcentrate the analyte, reduce the matrix effects, increase the selectivity of the procedures, and convert the sample to a suitable format for introducing it into detection systems. In the review, the various extraction and microextraction methods of these drugs in biological, real water, and wastewater samples were investigated. The theory of each technique was briefly addressed to understand the features and factors affecting each method. The extraction and microextraction methods were classified based on their application for antidepressants, and the advantages and disadvantages of each technique were reviewed. The new developments to overcome the limitations of each procedure were discussed. The investigation indicated the number of applications of liquid-phase microextraction for extracting antidepressants has been almost equal to that of solid-phase microextraction.

Alternative matrices in forensic toxicology: a critical review. Forensic Toxicol 2021; 40:1-18.

Abstract
Abstract
Purpose
The use of alternative matrices in toxicological analyses has been on the rise in clinical and forensic settings. Specimens alternative to blood and urine are useful in providing additional information regarding drug exposure and analytical benefits. The goal of this paper is to present a critical review on the most recent literature regarding the application of six common alternative matrices, i.e., oral fluid, hair, sweat, meconium, breast milk and vitreous humor in forensic toxicology.
Methods
The recent literature have been searched and reviewed for the characteristics, advantages and limitations of oral fluid, hair, sweat, meconium, breast milk and vitreous humor and its applications in the analysis of traditional drugs of abuse and novel psychoactive substances (NPS).
Results
This paper outlines the properties of six biological matrices that have been used in forensic analyses, as alternatives to whole blood and urine specimens. Each of this matrix has benefits in regards to sampling, extraction, detection window, typical drug levels and other aspects. However, theses matrices have also limitations such as limited incorporation of drugs (according to physical–chemical properties), impossibility to correlate the concentrations for effects, low levels of xenobiotics and ultimately the need for more sensitive analysis. For more traditional drugs of abuse (e.g., cocaine and amphetamines), there are already data available on the detection in alternative matrices. However, data on the determination of emerging drugs such as the NPS in alternative biological matrices are more limited.
Conclusions
Alternative biological fluids are important specimens in forensic toxicology. These matrices have been increasingly reported over the years, and this dynamic will probably continue in the future, especially considering their inherent advantages and the possibility to be used when blood or urine are unavailable. However, one should be aware that these matrices have limitations and particular properties, and the findings obtained from the analysis of these specimens may vary according to the type of matrix. As a potential perspective in forensic toxicology, the topic of alternative matrices will be continuously explored, especially emphasizing NPS.

Abstract
Vitreous humor has become in recent years an important alternative biological fluid in forensic toxicological analysis especially for the investigation of cases where alcohol and drugs of abuse are involved but there is limited scientific information regarding the distribution of antidepressant drugs in this material. This work aimed to study the distribution of antidepressant drugs in vitreous humor and to estimate the blood/vitreous humor concentration ratios of these drugs. For this purpose, a GC/MS method for the simultaneous determination of 9 antidepressant drugs, namely amitriptyline, nortriptyline, citalopram, clomipramine, fluoxetine, maprotiline, mirtazapine, sertraline and venlafaxine, and 4 of their metabolites, namely desmethylmaprotiline, desmethylmirtazapine, desmethylsertraline, O-desmethylvenlafaxine, was developed and validated. The developed method includes solid-phase extraction followed by derivatization with Heptafluorobutyric Anhydride. For all analytes, LOD and LOQ were 1.50 and 5.00ng/mL, respectively, and the calibration curves were linear within the dynamic range of 5.00-500.0ng/mL (R2≥0.990). The absolute recovery was found to be ≥86.3 % for all analytes. The accuracy (%Er) was found to range between -6.58 and 6.18 %, whereas the precision (%RSD) was less than 10.9 % for all analytes. The developed method was successfully applied to vitreous humor samples from 43 blood positive cases for antidepressant drugs. Whenever antidepressant drugs were detected in blood, they were also detected in the respective vitreous humor samples. The vitreous humor/blood concentration ratios were also calculated and were found to range from 0.04-7.07. Citalopram, mirtazapine, and its metabolite desmethylmirtazapine as well as venlafaxine and its metabolite O-desmethylvenlafaxine were the most identified substances in these samples (n≥4) and their results were better statistically evaluated. Our results suggest that vitreous humor could be an appropriate matrix for the determination of antidepressants in postmortem toxicology.

Abstract
Preparing a sample for analysis is a crucial step of many analytical procedures. The goal of sample preparation is to provide a representative, homogenous sample that is free of interferences and compatible with the intended analytical method. Green approaches to sample preparation require that the consumption of hazardous organic solvents and energy be minimized or even eliminated in the analytical process. While no sample preparation is clearly the most environmentally friendly approach, complete elimination of this step is not always practical. In such cases, the extraction techniques which use low amounts of solvents or no solvents are considered ideal alternatives. This paper presents an overview of green extraction procedures and sample preparation methodologies, briefly introduces their theoretical principles, and describes the recent developments in food, pharmaceutical, environmental and bioanalytical chemistry applications.

Abstract
Here, we present a fully validated method using a hollow-fibre liquid-phase microextraction technique for the determination by gas chromatography-mass spectrometry (GC-MS) of amphetamine (AMP), methamphetamine (MET), fenproporex (FEN), 3,4-methylenedioxymethamphetamine (MDMA), 3,4-methylenedioxyamphetamine (MDA) and 3,4-methylenedioxyethylamphetamine (MDEA) in whole blood. The validation parameters presented successful values within those recommended by the Scientific Working Group for Forensic Toxicology (SWGTox) in the Standard Practices for Method Validation in Forensic Toxicology. The limits of detection ranged from 1 to 3 ng/mL, and the limits of quantification ranged from 2 to 5 ng/mL. The determination coefficients (r2) ranged from 0.990 to 0.997, and the method presented good intraday and interday accuracy (from 90.4% to 97.2%) and satisfactory recovery (from 68% to 110%). No carryover was observed. The heteroscedasticity was tested, and only AMP presented homoscedasticity. Weighting factors were applied to correct the linearity of MET (1/x2), MDA (1/x), FEN (1/x1/2), MDMA (1/x2) and MDEA (1/y). Dilution integrity was tested at ratios of 1:2, 1:5 and 1:10, and all maintained intraday precision (from 94.9% to 99.3%) and interday precision (from 89.4% to 94.9%). The validated method was applied to six real whole blood samples from individuals suspected of consuming ecstasy, and MDMA, MDA and amphetamine were successfully identified and quantified.
