Advancing HIV Treatment Through Nanoparticles: A Precision Medicine Approach

The poor solubility and bioavailability of antiretroviral drugs complicate the manage-ment of Human Immunodeficiency virus. The efficacy of these medications is diminished due to restricted absorption in the gastrointestinal tract. Patients often exhibit a wide range of reactions attributable to fluctuations in blood drug concentrations. Achieving the target plasma concentra-tions is challenging and often necessitates higher dosages, which increases the risk of adverse ef-fects. The formulation of pharmaceuticals with poor solubility is a complex and costly process that hinders overall drug development. Given the limitations of traditional formulation strategies to address these issues, it is essential to explore alternative methods. The innovative method of nano-crystallization enhances the solubility and dissolution rates of pharmaceuticals by reducing their particle sizes to the nanoscale. The increased surface area improves the medication's solu-bility and bioavailability. Nanomedicine antiretroviral medications offer several advantages over their water-insoluble counterparts, including enhanced efficacy and safety, a higher drug load, and a more rapid onset of action. For this study, various databases, including Scopus, PubMed, Google Scholar, ScienceDirect, and Web of Science, were utilized to retrieve relevant literature on nanoparticles for HIV treatment. We examine the challenges associated with current treatment methods for HIV/AIDS and highlight the remarkable potential of nanotechnology to improve both the treatment and prevention of the disease through the development of antiretroviral therapy, gene therapy, immunotherapy, vaccinology, and microbicides. This review article focuses on var-ious nanomedicine approaches used to target HIV in different sites, including the spleen, liver, kidneys, gastrointestinal tract, lungs, and brain.
