Item Detección de medicamentos falsificados por espectroscopia en el infrarrojo cercano: “revisión sistemática”(Universidad Santiago de Cali, 2025) Narvaez Torres, Lisveth Rocio; Ríos Acevedo, Jhon Jairo (Director)Drug counterfeiting is a growing threat to public health worldwide, and it is estimated that between 10% and 50% of drugs used in low- and middle-income countries may be counterfeit. In light of this challenge, near-infrared spectroscopy (NIR spectroscopy) has emerged as a promising tool for the rapid and nondestructive detection of counterfeit drugs. In this study, we systematically reviewed recent literature (2017-2024) on the application of NIR spectroscopy for drug authentication and analyzed its advantages, limitations, and technological developments. The methodology included a comprehensive search of academic databases and applied rigorous selection criteria to ensure the quality and relevance of the included studies. The evaluation took into account, among other things, trial design, sample size, types of drugs analyzed and validation methods. The results show that the NIR method is effective in detecting different types of counterfeit drugs, such as antibiotics and analgesics. The combination of NIR with advanced data analysis methods, such as machine learning and artificial neural networks, has significantly improved the accuracy of drug ingredient identification and quantification. Challenges associated with formulation and packaging variability and strategies to reduce them, such as the use of spectral preprocessing techniques, will be discussed. The miniaturization of NIR instruments and their integration with other spectroscopic techniques will increase their usefulness in resource-limited environments.
