FAT EMULSION.

摘要

A fat emulsion developed to solve the problems of polyene antifungal antibiotics that they have such a severe toxicity as to limit the administration range thereof by suitably designing the administration form, thereby reducing the hemolytic toxicity and nephrotoxicity and facilitating the migration of a drug toward infected parts without adversely affecting the pharmacological action (antifungal action) on a molecular level. The emulsion comprises 0.005 to 5 % of a polyene antifungal antibiotic, 0.5 to 30 % of a simple lipid, and a phospholipid in an amount 0.15 to 2 times as large as that of the simple lipid, wherein the relative proportion of each ingredient is controlled to give a fine microemulsion of a mean particle diameter of at least 10 nm up to 100 nm. This emulsion can remarkably enhance the efficacy of polyene antifungal antibiotics such as Amphotericin B and is very useful for the development of medicines.
