Abstract
Methods and compositions are described for the preparation of bioactive agents entrapped in lipid vesicles the bilayers of which comprise a salt form of an organic acid derivative of a sterol, such as the tris-salt form of a sterol hemisuccinate, and to compositions comprising a mixture of tris(hydroxymethyl)aminomethane salt of cholesteryl hemisuccinate with either an antifungal compound or a peptide.
