Advancements in Targeted Drug Delivery: Innovations in Liposomal, Nanoparticle, and Vesicular Systems

Targeted drug delivery has become a miraculous tool in the new millennium of medicine to deliver the greatest therapeutic action, minimize systemic side effects and attain site-specific drug activity. This review offers advances in liposomal, nanoparticle and vesicular drug delivery systems with emphasis on their capacity for maximal bioavailability and regulation of drug release. There has been controversy over the use of some of these other carriers such as tablet formulations, proniosomes and other age-new carriers. Introduction of nanotechnology with biodegradable items and use of artificial intelligence has added new dimensions to patient-specific medicine based on the patient's need. In spite of these developments, regulatory problems, biocompatibility and scale-up manufacture are concerns that persist as barriers to universal clinical use. Some of the recent technologies such as 3D-printed pharmaceuticals, stimuli-responsive nanocarriers and drug design using artificial intelligence have the potential to bypass these concerns. Future direction is also set here in the focus on the application of green drug delivery concepts, precision medicine and combination regimens in setting the future of targeted drug delivery systems. Through ongoing research and technology development, these technologies are poised to revolutionize medicine by maximizing therapeutic effect, reducing side effects and maximizing drug delivery.
