Review on Liposomes: Structure, Composition, Drug Delivery Carrier and Current Status of Approved Drug

Liposomes are widely recognized and essential nano-sized drug delivery systems. They are phospholipid vesicles composed of cell membrane components and have been used as artificial cell models to mimic the structure and functions of cells, making them highly valuable in various biological analyses. Liposomes offer significant advantages and provide a wide range of applications as effective drug carriers in both pre- clinical and clinical trials. This review focuses exclusively on scalable techniques for liposome preparation and examines their strengths and limitations concerning industrial applicability. It also discusses recent advancements in biomedical applications, highlighting key development in commercially available formulations, clinical trials, and patents from recent years. Additionally, the review provides brief information on the classification, composition, and characterization of liposomes.
