Revolutionizing Drug Delivery: Innovations And Challenges In Nanotechnology

Abstract

Nanotechnology has emerged as a transformative force in revolutionizing drug delivery systems, offering innovative solutions to longstanding challenges in pharmaceutical therapy. This article provides a comprehensive overview of the latest innovations, advancements, and challenges in nanotechnology-enabled drug delivery. We discuss the diverse array of nanoparticle-based drug delivery systems, including liposomes, polymeric nanoparticles, dendrimers, and nanostructured lipid carriers, highlighting their unique properties and applications in targeted drug delivery. Emphasis is placed on the role of nanotechnology in enhancing drug solubility, stability, and bioavailability, as well as its potential for achieving site-specific drug delivery and controlled release kinetics. Furthermore, we explore the strategies employed to overcome biological barriers such as the blood-brain barrier, mucosal barriers, and cellular uptake mechanisms, enabling efficient drug delivery to target tissues or cells while minimizing off-target effects. Regulatory and safety considerations in the development and commercialization of nanomedicines are also discussed, emphasizing the importance of thorough characterization, preclinical safety assessment, and compliance with regulatory guidelines.
