Abstract
A method for loading liposomes with biopolymeric substances functional in humans involves combining a physiologically compatible solution of the biopolymeric substances with one or more dry, liposome-forming lipids, effecting a lipid-containing fraction, combining the lipid-containing fraction with an organic solvent, effecting an organic solvent fraction, and drying the organic solvent fraction, which effects a dry fraction of liposomes loaded with the biopolymeric substances.
