Targeted Drug Delivery Systems: Innovations and Clinical Implications

The review study examines the development along with the importance of tailored drug delivery systems (DDS) in improving treatment efficacy while reducing side effects. It focuses on a variety of new carrier structures, such as liposomes, niosomes, dendrimers, nanoparticles, & microspheres, which are critical to the delivery of drugs success. The paper examines the history of these structures, beginning with the introduction of disposable acrylate nanoparticles in 1977 and focusing on nanotechnology breakthroughs that have resulted in the creation of smart polymers or hydrogels. These advancements enable the stable functioning of drug delivery methods that adapt to physiological variations like blood sugar levels, pH, and temperatures. The review also addresses the challenges faced by conventional drug delivery methods and the pressing need for more efficient alternatives. By integrating biological components like integrin ligands and antibodies, targeted DDS can deliver pharmaceutical agents with higher precision to specific organs or cell types. Despite the promising results observed in preclinical studies, the paper notes that only a limited number of these technologies have received FDA approval. Overall, the review underscores the ongoing quest for innovation in drug delivery systems, aiming to improve patient outcomes through personalized medicine approaches.
