Abstract: This invention provides a composition and method for increasing fat absorption from the intestine by increasing the amount of lysophosphatidylcholine in the intestine. The composition comprises phospholipase A2 and lipid molecules.

Abstract: A composition comprised of non-esterified fatty acids having 14-18 carbon atoms; monoglycerides which are monoesters of glycerol and fatty acids having 14-18 carbon atoms; lysophosphatidyl choline in which the fatty acid moiety has 14-18 carbon atoms and a drug is disclosed. The composition is useful for the delivery of orally-administered drugs. The composition is also useful as a source of readily absorbable fat. When used in this manner, the composition is comprised of non-esterified fatty acids having 14-18 carbon atoms; monoglycerides which are monoesters of glycerol and fatty acids having 14-18 carbon atoms; lysophosphatidyl choline in which the fatty acid moiety has 14-18 carbon atoms. A method of making the compositions disclosed is also described.

Abstract: A composition is disclosed containing nonesterified fatty acids having 14-22 carbon atoms of saturated, unsaturated and polyunsaturated fatty acid, monoglycerides which are monoesters of glycerol and fatty acids having 14-22 carbon atoms of saturated, unsaturated and polyunsaturated fatty acid, lysophosphatidylcholine in which the fatty acid moiety has 14-22 carbon atoms of saturated, unsaturated and polyunsaturated fatty acid and bicarbonate. The compositions can optionally also contain bile salts. These compositions form submicron size colloidal particles and can act as vehicles for transporting orally administered drugs, sources of calories in the form of readily absorbable and sustained absorption of fats, sources of readily absorbable polyunsaturated fat and as particles for topical application to the skin. A method of making these particles is also described.

Abstract: Methods for making lysophosphatidylcholine are provided, comprising hydrolysis of a mixture of phosphatidylcholine and an agent with phospholipase A.sub.2. Also disclosed are methods for making a lipid matrix of lysophosphatidylcholine, monoglyceride and fatty acid.

Abstract: A method of assessing the mixed lipid transport properties of a drug is provided. The method includes providing a mixed lipid composition which incorporates a drug in colloidal particles, applying the particles to a size exclusion chromatography column, eluting free drug and drug incorporated into mixed lipid particles from the column, and determining the elution profiles of the free drug and the drug incorporated into mixed lipid particles. Drugs which elute with the mixed lipid particles are considered to have stable transport properties when incorporated into the mixed lipid particles.
