Method of making uniformly sized liposomes and liposomes so made.

摘要

A composition whereby pharmaceutically active ingredients such as the bis-anthracyclines disclosed and claimed in European Application Publication No. 0 004 467 may be effectively delivered to selected sites in a mammalian organism is made by incorporating the ingredients within uniformly sized liposomes. Uniformly sized liposomes are made by extrusion of more or less randomly sized liposomes at high pressure through a very fine orifice.
