Abstract
Liposomes are unique novel drug delivery carriers that favor the effective transportation of pharmaceuticals. These vesicles acquire one or more phospholipid bilayer membranes, and an inner aqueous core can carry both aqueous and lipid drugs. While hydrophilic molecules can be confined in the aqueous core, hydrophobic molecules are injected into the bilayer membrane. Liposomes have many benefits as a drug delivery method, including biocompatibility, the capacity to carry large drug payloads, and a variety of physicochemical and biological parameters that can be altered to influence their biological characteristics. In addition, being a size of 10-100 nm range can have numerous additional benefits, including enhanced pharmacokinetics, clever escape from the reticuloendothelial system, greater in vivo stability, longer and site-specific administration, and increased internalization in tumor tissue (enhanced permeability and retention impact). The current review focuses on the structural composition of liposomes, formulation technologies, and suitable case studies for optimizing biopharmaceutical performance. Moreover, clinical trials and marketed formulations of liposomes have been also stated in the prior art.
