Nanotechnology-Based Drug Delivery Systems: Enhancing Bioavailability and Targeted Therapeutics

Abstract

Nanotechnology has revolutionized the field of drug delivery by enabling precise targeting, controlled release, and improved bioavailability of therapeutics. This research examines recent advancements in nanotechnology-based drug delivery systems, focusing on their design, mechanisms, and clinical applications. A mixed-method approach was employed, including a review of 60 peer-reviewed studies, case analyses of clinically approved nanomedicines, and surveys of pharmaceutical researchers. Key findings indicate that nanoparticle-based systems—such as liposomes, polymeric nanoparticles, dendrimers, and metallic nanoparticles—enhance drug solubility, reduce systemic toxicity, and enable site-specific delivery. Data analysis shows significant improvements in therapeutic efficacy (up to 35%), reduced dosage requirements, and minimized adverse effects. Challenges identified include formulation stability, immunogenic responses, and high production costs. The study highlights the potential of integrating nanotechnology with targeted therapeutics to improve patient outcomes and outlines future directions for research and clinical translation.
