Novel Drug Delivery Systems: Innovations In Drug Carriers For Targeted Therapy

The development of novel drug delivery systems (NDDS) has revolutionized the field of targeted therapy, providing innovative solutions to overcome the limitations of traditional drug delivery methods. This review explores the latest advancements in drug carriers, focusing on their design, functionality, and applications in targeted therapy. Various types of drug carriers, including liposomes, nanoparticles, dendrimers, polymer-drug conjugates, and micelles, are examined for their role in enhancing the bioavailability, stability, and therapeutic efficacy of drugs. Special attention is given to the use of stimuli-responsive carriers that release their therapeutic payload in response to specific physiological or external triggers, offering precise control over drug release profiles. Additionally, the integration of targeting ligands, such as antibodies, peptides, and aptamers, is discussed for achieving selective drug delivery to diseased cells while minimizing off-target effects and reducing systemic toxicity. The review also highlights the potential of multifunctional drug carriers, which combine diagnostic and therapeutic capabilities, paving the way for theranostics and personalized medicine. Challenges in clinical translation, including safety, scalability, and regulatory considerations, are also addressed. Overall, this review provides a comprehensive overview of the current state of NDDS, emphasizing their significance in advancing targeted therapy and improving patient outcomes in various diseases, including cancer, cardiovascular disorders, and neurodegenerative conditions.
