Abstract
Lipid emulsions employed in drug delivery systems are stabilized by the natural emulsifying agent lecithin, phospholipids obtained from egg or soybean. These are o/w emulsions formulated by soybean oils or medium chain triglycerides as oil phases and similar to commercially available fat emulsions employed in parenteral nutrition. Lipid emulsions are useful microparticle drug carriers in various therapeutic applications owing to their ability to incorporate lipid-soluble drugs or prodrugs modified from water-soluble drugs in oil phase of dispersing systems. Recent topics containing gene delivery in the study of lipid emulsions are reviewed.
