Advances in Drug Delivery Systems

Review Article

Abstract

Drug delivery systems have undergone remarkable advancements in recent years, revolutionizing the way therapeutic agents are administered and enhancing their efficacy and safety profiles. This review explores the latest developments in drug delivery technologies, including biodegradable polymers, nanocarriers, and smart delivery systems responsive to specific physiological conditions. Nanotechnology-based delivery platforms, such as liposomes, dendrimers, and polymeric nanoparticles, have demonstrated impressive potential in improving drug targeting, bioavailability, reducing adverse effects, and facilitating controlled release. The increasing use of biodegradable polymers like poly(glycolic acid) (PGA) and poly(lactic acid) (PLA) enables localized and sustained drug delivery. Smart delivery systems employing stimuli-responsive materials enable drug release triggered by environmental cues like pH, temperature, and enzyme activity. Furthermore, the integration of personalized medicine and advanced drug delivery technologies is enabling more efficient and tailored therapeutic approaches. This review highlights the prevailing trends, challenges, and future prospects in drug delivery systems, emphasizing their pivotal role in advancing next-generation therapies
