ROLE OF RESEARCH AND DEVELOPMENT IN NOVEL DRUG DELIVERY SYSTEM–A REVIEW

The rising demand for improved therapeutic outcomes and decreased side effects in the pharmaceutical sector has spurred a new wave of innovation and research in novel drug delivery systems. These systems aim to overcome the limitations of traditional drug administration methods, such as short half-life, poor targeting, low solubility, and bioavailability. As the fields of pharmacy, materials science, and biomedicine advance and intersect, the focus on developing efficient and safe drug delivery systems, including biopharmaceutical formulations, has grown significantly both nationally and internationally. This article provides an overview of the latest advancements in drug delivery systems, categorized into four key areas: carrier-based and coupling-based targeted drug delivery systems, intelligent drug delivery systems, and drug delivery devices, according to their primary objectives and methodologies. Furthermore, it critically examines the technological barriers, current research challenges, and future trends in the application of novel drug delivery systems.
