Restoration and Sustenance of Nano Drug Delivery Systems: Potential, Challenges, and Limitations

Drug delivery systems refer to technologies and methods designed to deliver pharmaceutical compounds, such as drugs or therapeutic agents, to their intended target sites within the body in a controlled and precise manner. The purpose of drug delivery systems is to administer an active dose of medication while optimizing safety and efficacy by precise control over the location, pace, and timing of a drug's release within the body of a lower total dosage while also lessening the negative effects of the drugs associated with dosage. An overview of drug delivery systems provides a comprehensive exploration of technologies and strategies employed for the controlled and targeted administration of pharmaceutical compounds. This review encompasses essential aspects such as drug encapsulation, release kinetics, and delivery routes, highlighting on the drug delivery systems like nanotechnology, microparticles, vesicular systems and personalized medicine. Over the past few decades, substantial advancements in drug delivery technology have facilitated the development of personalized medicine. Nanotechnology has revolutionized the treatment of many diseases such as cancer in particular. Nanoparticles are not only useful as drug delivery systems but also as pharmaceuticals and diagnostics. By offering insights into the latest advancements, challenges, and potential applications, this overview serves as a valuable resource for researchers, clinicians, and pharmaceutical professionals seeking to enhance therapeutic efficacy and patient compliance in the field of drug delivery. Despite the fact that many of these technologies have reached the market and proven their benefits, the comprehensive review also spotlights the shortcomings of the current drug delivery methods as well as potential future avenues for enhanced use and performance.
