Introduction

Therapeutic Drug Monitoring (TDM) stands at the forefront of personalized medicine, ensuring optimal drug efficacy and safety by tailoring treatments to individual patient responses. Traditionally, TDM relied on periodic blood draws and laboratory analysis to maintain therapeutic drug levels within a narrow range. However, the landscape of TDM is rapidly evolving with the advent of groundbreaking technologies. These advancements not only promise real-time monitoring but also offer unprecedented insights into drug metabolism, pharmacokinetics and patient-specific variability. In recent years, the convergence of nanotechnology, microfluidics and biosensors has paved the way for miniature, portable devices capable of continuous monitoring at the point of care. These devices enable clinicians to adjust drug dosages in real time, minimizing the risk of adverse effects and therapeutic failures.

Moreover, the integration of artificial intelligence (AI) and machine learning algorithms has empowered predictive modeling of drug responses based on patient demographics, genetic profiles and environmental factors. This review explores the transformative impact of emerging technologies on therapeutic drug monitoring. By examining the latest innovations in sensor technology, data analytics and bioinformatics, we delve into how these developments are reshaping clinical practices, enhancing patient outcomes and accelerating the shift towards precision medicine. Therapeutic drug monitoring (TDM) plays a crucial role in modern medicine, ensuring optimal drug dosing to maximize efficacy and minimize adverse effects. Traditionally, TDM has relied on measuring drug concentrations in blood or plasma, but advancements in technology are reshaping this field, offering new methods that promise greater precision, efficiency and patient outcomes.

Description

Mass spectrometry (MS) and high-performance liquid chromatography (HPLC)

Mass spectrometry and HPLC have been pivotal in enhancing the accuracy and sensitivity of drug monitoring. These techniques enable precise quantification of drug levels in biological samples with minimal sample preparation. Recent developments in MS have focused on miniaturization and automation, allowing for faster turnaround times and broader applicability across a range of drugs and metabolites [1].

Microsampling and microfluidics

Microsampling technologies are revolutionizing TDM by requiring smaller sample volumes, which is particularly advantageous in pediatric and geriatric populations. Microfluidic devices further streamline the process by integrating sample preparation, analysis and data interpretation into a single platform. These advancements not only reduce patient discomfort but also enable realtime monitoring at the point of care.

Biosensors and wearable devices

The advent of biosensors and wearable devices has ushered in a new era of personalized medicine. Biosensors can detect drug levels in bodily fluids such as sweat or interstitial fluid, providing continuous monitoring without invasive procedures. Wearable devices equipped with biosensors offer realtime feedback to patients and healthcare providers, facilitating immediate adjustments to drug regimens based on individual responses [2,3].

Artificial intelligence (AI) and machine learning (ML)

AI and ML algorithms are transforming TDM by analyzing vast datasets to predict optimal dosing regimens and individualized therapeutic targets. These technologies integrate patient-specific factors such as age, weight, genetic makeup and comorbidities to generate personalized recommendations. AIdriven decision support systems are enhancing clinical decision-making, reducing variability in drug response and minimizing the risk of adverse reactions.

Pharmacogenomics

Understanding how genetic variations influence drug metabolism and response is crucial for precision medicine. Pharmacogenomics uses genetic testing to tailor drug therapy to an individual's genetic profile, optimizing efficacy and minimizing side effects. Advances in sequencing technologies and bioinformatics are expanding the application of pharmacogenomics in routine clinical practice, guiding TDM strategies towards more personalized and effective treatments [4].

Blockchain and data security

Ensuring the integrity and confidentiality of TDM data is essential for maintaining patient trust and compliance. Blockchain technology offers decentralized and secure storage of patient records and monitoring data, protecting against unauthorized access and tampering. By enhancing data interoperability and transparency, blockchain solutions support collaborative research efforts and facilitate seamless integration of TDM insights into electronic health records.

Future directions and challenges

While these technologies hold immense promise, several challenges remain, including standardization of assays, validation of new methodologies and integration into existing healthcare infrastructures. Regulatory considerations and cost-effectiveness also influence the adoption of these innovations on a broader scale. Collaboration between researchers, clinicians and industry stakeholders is essential to overcome these challenges and harness the full potential of emerging technologies in revolutionizing therapeutic drug monitoring [5].

Conclusion

The convergence of advanced analytical techniques, personalized medicine approaches and computational tools is reshaping the landscape of therapeutic drug monitoring. These innovations not only enhance clinical decision-making but also pave the way for precision medicine paradigms tailored to individual patient needs. As these technologies continue to evolve, the future of TDM promises more effective and patient-centric therapeutic interventions.
