Topic: “Formulating Liposomes and Importance of Vesicle Size Control”
Speaker:Yvonne Perrie – Professor, Strathclyde Institute of Pharmacy & Biomedical Sciences, University of Strathclyde, Glasgow
Abstract: Liposomes are amongst the most established particulate-based drug delivery systems and they can be used to deliver a wide range of drugs, genes and vaccines. Through appropriate selection of lipids and preparation methods, liposomes can be tailored to accommodate a variety of drugs, and can be optimised in a range of characteristics including: size, charge, bilayer rigidity, surface characteristics, drug retention and controlled drug release. The parenteral route is the most commonly adopted in clinical use. Intravenously injected liposomes interact with blood opsonins and are removal from the blood circulation by the mononuclear phagocyte system, mostly by fixed macrophages in the liver and spleen. This rate of clearance is dependent on vesicle size, lipid composition and surface charge. When administered via the intramuscular or subcutaneous routes, liposomes tend to enter the lymphatic system including the lymph nodes draining the injected site. This may be advantageous in vaccine design. However again, one of the key factors controlling the fate of liposomes administered via this route is their vesicle size. Via this Webinar we will investigate the impact of liposome size and formulation on their biodistribution and discuss the importance of vesicle size control in liposome formulation and manufacture.
