Abstract
A preparation comprising a fat emulsion of fat microparticles wherein said emulsion contains a stabilizer consisting essentially of a fatty acid, a basic amino acid and a saccharide is provided. In the preparation comprising a fat emulsion of fat microparticles of the present invention, said microparticles having a mean particle diameter of at most 100 nm are stable, and so the microparticles remain in blood without being uptaken by liver. Therefore in case of administering a pharmaceutical preparation prepared by using the above-mentioned preparation of the present invention, the pharmacological activity may be expressed at a desired site. Thus the preparation is extremely useful as a drug carrier for drug delivery system. Furthermore, the pharmaceutical preparation of the present invention which is lyophilized can be easily and rapidly reconstituted into the pharmaceutical preparation comprising a fat emulsion of stable fat microparticles having a mean particle diameter of about at most 100 nm by adding distilled water, even after a long-term storage.
