Abstract
Simultaneous monitoring of plasma concentration levels of multiple antiepileptic drugs (AEDs) is essential for dose adjustment in comprehensive epilepsy treatment, necessitating a sensitive technique for accurate extraction and determination of AEDs. Herein, a magnetic solid-phase extraction (MSPE) technique on the basis of modified biochar (BC) is investigated to extract four AEDs from plasma, in conjunction with high performance liquid chromatography. BC derived from Zizyphus jujuba seed shells was activated by phosphoric acid (PBC) and magnetized via coprecipitation to produce MPBC. The MPBCCD obtained after modification with β-cyclodextrin (CD) was characterized and evaluated for adsorption. It exhibited fast adsorption kinetics based on second-order kinetics and satisfactory adsorption capacity for AEDs. Then it was employed as the MSPE adsorbent and the influencing parameters were optimized. The enrichment factor was 18.75. The validation analysis revealed a favorable linearity that ranged from 0.04 to 20 μg·mL-1 along with a low limit of detection of 6.85 to 10.19 ng·mL-1. The recovery of the AEDs ranged from 78.7 to 109.2 %, with relative standard deviations below 6.7 %. Using quantum chemistry theory calculations and experimental results analysis, the adsorption mechanism was investigated. It disclosed that the suggested strategy built upon MPBCCD was appropriate for the assessment of AEDs in plasma and expanded the usage of BC as the environmentally favorable matrix for the analysis of biological samples.

Abstract
PURPOSE Therapeutic drug monitoring of plasma lamotrigine (LTG) has customarily been carried out in order to prevent some its adverse effects. For forensic purposes, determination of LTG in plasma is an useful tool in cases of accidental overdose or suicidal attempts. Currently, there are several analytical methods available including some based on LC tandem mass spectrometry techniques, but simple and accessible LC-UV methods still can be useful for the purpose. Here we report on a new high-performance liquid chromatography method for the determination of lamotrigine in human plasma which has been developed and validated including selectivity, sensitivity, accuracy, precision and recovery studies. METHODS Lamotrigine and the internal standard chloramphenicol were extracted from plasma using liquid-liquid extraction using small volumes of buffer and ethylacetate. Detection was monitored at 305.7 and 276.0 nm for lamotrigine and chloramphenicol, respectively. RESULTS The method was linear concentration dependence within the range of 0.1-10 µg/ml, with a mean coefficient of correlation r = 0.993. The limit of detection (LOD) was 0.04 µg/ml and the limit of quantification (LOQ) was 0.1 µg/ml. Intra and interday precision values were lower than 9.0% at all concentrations studied. The intra and interday accuracy values ranged from - 7.6 to 10.1%. Recovery was found to be 98.9% or higher. The method here described was successfully applied to 11 postmortem blood samples received at the Forensic Sciences Institute of Santiago de Compostela (Spain). CONCLUSION A new HPLC method for the determination of lamotrigine in human plasma was developed and validated. A liquid-liquid extraction using small volumes of buffer and ethylacetate was optimized. The proposed method is suitable for forensic toxicological analysis.

Titania-based fabric phase sorptive extraction approach for the determination of antiepileptic drugs, levetiracetam and lamotrigine in urine samples using high-performance liquid chromatography-photo diode array detection. J Chromatogr A 2024; 1719:464737.

Abstract
A new fabric phase sorptive extraction (FPSE) based separation and enrichment method was developed for sensitive determination of two antiepileptic drug molecules, Levetiracetam (LEV) and Lamotrigine (LTG). The analysis of these drug molecules was performed with high-performance liquid chromatography equipped with photodiode array detector (HPLC-PDA) after FPSE. HPLC analysis was carried out by using phenyl hexyl column, under isocratic conditions with the mobile phase composed of pH 3.0 buffer-acetonitrile (77:23 v: v). All parameters affecting the separation and enrichment process were studied and optimized step by step. The linear working range of the developed method was calculated in the range of 10.0-1000.0 ng mL-1 for both the drug molecules (LEV and LTG). The limits of detection of the method (LODs) were calculated as 2.72 and 3.64 ng mL-1, respectively. The relative standard deviation (%RSD) values of the developed method as an indicator of precision were varied between 4.0 and 7.3. The accuracy of the optimized FPSE method was determined by the recovery tests utilizing spiked samples and results were assessed in the range from 94.6 to 106.3%. This is the first application of sol-gel Titania polycaprolactone-polydimethylsiloxane-polycaprolactone (Ti-PCAP-PDMS-PCAP) based FPSE membrane in the determination of antiepileptic drug molecules.

Abstract
With the rapid development of clinical pharmacy in China, therapeutic drug monitoring (TDM) has become an essential tool for guiding rational clinical drug use and is widely concerned. TDM is a tool that combines pharmacokinetic and pharmacodynamic knowledge to optimize personalized drug therapy, which can improve treatment outcomes, reduce drug-drug toxicity, and avoid the risk of developing drug resistance. To effectively implement TDM, accurate and sophisticated analytical methods are required. By researching the literature published in recent years, we summarize the types of commonly monitored drugs, therapeutic windows, and clinical assays and track the trends and hot spots of therapeutic drug monitoring. The purpose is to provide guidelines for clinical blood drug concentration monitoring, to implement individualized drug delivery programs better, to ensure the rational use of drugs for patients, and to provide a reference for the group to carry out related topics in the future.

Abstract
Therapeutic drug monitoring is an established practice for a small group of drugs, particularly those presenting narrow therapeutic windows, for which there is a direct relationship between concentration and pharmacological effects at the site of action. Drug concentrations in biological fluids are used, in addition to other clinical observation measures, to assess the patient's status, since they are the support for therapy individualization and allow assessing adherence to therapy. Monitoring these drug classes is of great importance, as it minimizes the risk of medical interactions, as well as toxic effects. In addition, the quantification of these drugs through routine toxicological tests and the development of new monitoring methodologies are extremely relevant for public health and for the well-being of the patient, and it has implications in clinical and forensic situations. In this sense, the use of new extraction procedures that employ smaller volumes of sample and organic solvents, therefore considered miniaturized and green techniques, is of great interest in this field. From these, the use of fabric-phase extractions seems appealing. Noteworthy is the fact that SPME, which was the first of these miniaturized approaches to be used in the early '90s, is still the most used solventless procedure, providing solid and sound results. The main goal of this paper is to perform a critical review of sample preparation techniques based on solid-phase microextraction for drug detection in therapeutic monitoring situations.

Abstract
Background:
Lamotrigine (LTG) is a broad-spectrum and first-line anti-epileptic drug.
To monitor the serum levels of LTG in epileptic seizures patients, high-performance liquid chromatography
with diode-array detection (HPLC-DAD) and ultra-performance liquid chromatography--
tandem mass spectrometry (UPLC-MS/MS) methods were established and compared.
Methods:
Imatinib was used as the internal standard (IS) for both methods. LTG and IS were detected
at 246 nm by HPLC-DAD. In UPLC-MS/MS, LTG and IS positive ion were detected by
multiple reaction monitoring (MRM), with m/z of 256/210.9 and 494/394.02, respectively. A total
of 37 blood samples from epileptic patients were determined and studied by these two methods.
Results:
There was an acceptable linearity for the two methods. The concentration range of LTG
was 0.59 ~ 22.20 mg/L by HPLC, and 0.28 ~ 23.97 mg/L by UPLC-MS/MS. The Pearson regression
coefficient of Deming regression was 0.9653 (95% CI: 0.9332 to 0.9821). Bland–Altman
method demonstrated that the concentration of LTG determined by UPLC-MS/MS was 8.3% higher
than that determined by HPLC (limits of agreement, -32.0% to +48.6%).
Conclusion:
There was a significant correlation between the two methods. Both HPLC and UPLC-
MS/MS can be used for routine clinical monitoring of LTG.

Abstract
A sensitive and efficient analytical process for detecting lamotrigine in acidic solution based in ultra-high-performance liquid chromatography-diode array detector (UPLC-DAD) was developed; the stationary phase used was a C8, 150 × 4.6 mm, 2.6 µm. The mobile phase consisted of acetonitrile/acidified water (0.01% H3PO4 and 0.005% triethylamine, pH 2.4) (25 : 75 v/v). Limits of detection and quantification were 0.02 µg/mL and 0.05 µg/mL, respectively. The working interval for the evaluation of the method ranged from 0.05 to 12 µg/mL, and the linear fit of the experimental data has a value of r2≥0.98. Before quantifying lamotrigine in plasma of patients with bipolar disorder, lamotrigine was released from plasma proteins with a 0.2 M sodium hydroxide solution, and then proteins were removed by precipitation with acetonitrile. Afterward, the lamotrigine base was dissolved in ethyl acetate. This extract was reconstituted in potassium phosphate solution (pH 2.4) to obtain more than 98% of lamotrigine protonated in N2, which was detected and quantified as indicated above. The absolute percentage of lamotrigine recovery is ≥80% for all tested concentration levels. The accuracy and precision of the method have %CV values <4% for the lamotrigine levels of 3, 6, and 9 µg/mL. The correlation coefficient for the used concentration range is 0.99. The analytical method is precise and sensitive to measure lamotrigine levels expected in plasma of BD patients and these levels were in the therapeutic dose range.

Abstract
A sensitive fluorescent nanoprobe is reported for the determination of lamotrigine after its preconcentration by magnetic graphene oxide nanocomposite. The fluorescent nanoprobe is based on the quenching effect of lamotrigine on the nitrogen graphene quantum dots fluorescence at 440 nm, through strong hydrogen bonding. Under optimum conditions, the quenching fluorescent intensity of nitrogen graphene quantum dots shows linearity with the lamotrigine concentration in the range of 2.0-45.0 µg L-1, limits of detection (LOD), and quantification of 0.39 and 1.28 µg L-1 respectively. The parameters affecting the extraction and determination of lamotrigine were optimized via the central composite design (CCD) and one at the time method, respectively. The developed method was successfully employed for the extraction and quantification of lamotrigine in biological samples.

Abstract
Personalized antibiotherapy ensures that the antibiotic concentration remains in the optimal therapeutic window to maximize efficacy, minimize side effects, and avoid the emergence of drug resistance due to insufficient dosing. However, such individualized schemes need frequent sampling to tailor the blood antibiotic concentrations. To optimally integrate therapeutic drug monitoring (TDM) into the clinical workflow, antibiotic levels can either be measured in blood using point-of-care testing (POCT), or can rely on noninvasive sampling. Here, a versatile biosensor with an antibody-free assay for on-site TDM is presented. The platform is evaluated with an animal study, where antibiotic concentrations are quantified in different matrices including whole blood, plasma, urine, saliva, and exhaled breath condensate (EBC). The clearance and the temporal evaluation of antibiotic levels in EBC and plasma are demonstrated. Influence of matrix effects on measured drug concentrations is determined by comparing the plasma levels with those in noninvasive samples. The system's potential for blood-based POCT is further illustrated by tracking ß-lactam concentrations in untreated blood samples. Finally, multiplexing capabilities are explored successfully for multianalyte/sample analysis. By enabling a rapid, low-cost, sample-independent, and multiplexed on-site TDM, this system can shift the paradigm of "one-size-fits-all" strategy.

Abstract
Perampanel is a third-generation antiepileptic drug (AED), while lamotrigine is a second-generation AED. Both drugs are subject to extensive pharmacokinetic variability between different patients. Furthermore, it has been reported that perampanel and lamotrigine may be implied in pharmacokinetic drug-drug interactions with other AEDs such as carbamazepine or valproate, with consequent alterations of plasma concentrations. This emphasizes the relevance of therapeutic drug monitoring of perampanel and lamotrigine with appropriate bioanalytical methods. Herein, the development and validation of a bioanalytical techique for the simultaneous quantification of perampanel and lamotrigine in human plasma samples is described. The reported method is based on high-performance liquid chromatography coupled with diode-array detection (HPLC-DAD) and sample preparation consists of liquid-liquid extraction. Chromatographic separation of the analytes (lamotrigine and perampanel) and the internal standard (entacapone) was achieved in 12 min on a reversed-phase C18 column at 40 °C by applying a gradient elution program with a mobile phase composed of 0.1% ortho-phosphoric acid pH 2.79 (A) and acetonitrile (B) pumped at 1.0 mL/min. Perampanel was quantified at 320 nm while lamotrigine and the internal standard were monitored at 306 nm. Calibration curves were linear in the concentration range of 0.03-4.5 µg/mL (r2 = 0.9978) for perampanel and in the concentration range of 0.25-30 µg/mL (r2 = 0.9981) for lamotrigine. Overall precision did not exceed 14.3% and accuracy ranged from -6.08 to 12.66%. Some drugs potentially co-prescribed with perampanel and lamotrigine were tested and did not interfere with the retention times of the analytes and internal standard. The method was then successfully applied for the quantification of perampanel and lamotrigine in plasma samples obtained from 42 drug-resistant epileptic patients admitted to the Coimbra University Hospital Centre (CHUC.EPE, Coimbra, Portugal). In conclusion, it is a suitable method for the therapeutic drug monitoring of lamotrigine and perampanel in drug-resistant epileptic patients, as well as, for the assessment of drug-drug interactions. It can also be adopted by hospitals and laboratories, when HPLC with fluorescence and mass spectrometry detections are unavailable.

Abstract
Therapeutic drug monitoring (TDM) is a tool used to integrate pharmacokinetic and pharmacodynamics knowledge to optimize and personalize various drug therapies. The optimization of drug dosing may improve treatment outcomes, reduce toxicity, and reduce the risk of developing drug resistance. To adequately implement TDM, accurate and precise analytical procedures are required. In clinical practice, blood is the most commonly used matrix for TDM; however, less invasive samples, such as dried blood spots or non-invasive saliva samples, are increasingly being used. The choice of sample preparation method, type of column packing, mobile phase composition, and detection method is important to ensure accurate drug measurement and to avoid interference from matrix effects and drug metabolites. Most of the reported procedures used liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) techniques due to its high selectivity and sensitivity. High-performance chromatography with ultraviolet detection (HPLC-UV) methods are also used when a simpler and more cost-effective methodology is desired for clinical monitoring. The application of high-performance chromatography with fluorescence detection (HPLC-FLD) with and without derivatization processes and high-performance chromatography with electrochemical detection (HPLC-ED) techniques for the analysis of various drugs in biological samples for TDM have been described less often. Before chromatographic analysis, samples were pretreated by various procedures-most often by protein precipitation, liquid-liquid extraction, and solid-phase extraction, rarely by microextraction by packed sorbent, dispersive liquid-liquid microextraction. The aim of this article is to review the recent literature (2010-2020) regarding the use of liquid chromatography with various detection techniques for TDM.

Abstract
Recent technological advances have stimulated efforts to bring personalized medicine into practice. Yet, traditional application fields like therapeutic drug monitoring (TDM) have remained rather under-appreciated. Owing to clear dose-response relationships, TDM could improve patient outcomes and reduce healthcare costs. While chromatography-based routine practices are restricted due to high costs and turnaround times, biosensors overcome these limitations by offering on-site analysis. Nevertheless, sensor-based approaches have yet to break through for clinical TDM applications, due to the gap between scientific and clinical communities. We provide a critical overview of current TDM practices, followed by a TDM guideline to establish a common ground across disciplines. Finally, we discuss how the translation of sensor systems for TDM can be facilitated, by highlighting the challenges and opportunities.

Abstract
Biological samples are usually complex matrices due to the presence of proteins, salts and a variety of organic compounds with chemical properties similar to those of the target analytes. Therefore, sample preparation is often mandatory in order to isolate the analytes from troublesome matrices before instrumental analysis. Because the number of samples in drug development, doping analysis, forensic science, toxicological analysis, and preclinical and clinical assays is steadily increasing, novel high throughput sample preparation approaches are calling for. The key factors in this development are the miniaturization and the automation of the sample preparation approaches so as to cope with most of the twelve principles of green chemistry. In this review, recent trends in sample preparation and novel strategies will be discussed in detail with particular focus on sorptive and liquid-phase microextraction in bioanalysis. The actual applicability of selective sorbents is also considered. Additionally, the role of 3D printing in microextraction for bioanalytical methods will be pinpointed.

Abstract
<P>Background: The electrochemical sensing of drugs in pharmaceutical formulations and biological matrices using molecular-imprinting polymer (MIP) as a recognition element combined with different electrochemical signal transduction has been widely developed. The MIP electrochemical sensors based on nanomaterials such as graphene, carbon nanotubes, nanoparticles, as well as other electrode modifiers incorporated into the MIPs to enhance the performance of the sensor, have been discussed. The recent advances in enantioselective sensing using MIP-based electrochemical sensors have been described. </P><P> Methods: The molecular imprinting has more than six decades of history. MIPs were introduced in electrochemistry only in the 1990s by Mosbach and coworkers. This review covers recent literature published a few years ago. The future outlook for sensing, miniaturization and development of portable devices for multi-analyte detection of the target analytes was also given. </P><P> Results: The growing pharmaceutical interest in molecularly imprinted polymers is probably a direct consequence of its major advantages over other analytical techniques, namely, increased selectivity and sensitivity of the method. Due to the complexity of biological samples and the trace levels of drugs in biological samples, molecularly imprinted polymers have been used to improve the response signal, increase the sensitivity, and decrease the detection limit of the sensors. The emergence of nanomaterials opened a new horizon in designing integrated electrochemical systems. The success of obtaining a high-performance electrochemical sensor based on MIPs lies in the kind of material that builds up the detection platform. </P><P> Conclusion: The novel approaches to produce MIP materials, combined with electrochemical transduction to develop sensors for screening different pharmaceutically active compounds have been overviewed. MIPs may appear indispensable for sensing in harsh conditions, or sensing that requires longterm stability unachievable by biological receptors. The electrochemical sensors provide several benefits including low costs, shortening analysis time, simple design; portability; miniaturization, easy-touse, can be tailored using a simple procedure for particular applications. The performance of sensor can be improved by incorporating some conductive nanomaterials as AuNPs, CNTs, graphene, nanowires and magnetic nanoparticles in the polymeric matrix of MIP-based sensors. The application of new electrochemical sensing scaffolds based on novel multifunctional-MIPs is expected to be widely developed and used in the future.</P>

Abstract
Saliva, as the first body fluid encountering with the exogenous materials, has good correlation with blood and plays an important role in bioanalysis. However, saliva has not been studied as much as the other biological fluids mainly due to restricted access to its large volumes. In recent years, there is a growing interest for saliva analysis owing to the emergence of miniaturized sample preparation methods. The purpose of this paper is to review all microextraction methods and their principles of operation. In the following, we examine the methods used to analyze saliva up to now and discuss the potential of the other microextraction methods for saliva analysis to encourage research groups for more focus on this important subject area.
