Abstract: A composition for transdermal and dermal administration of interferon-&agr; is described. The composition is comprised of lipid vesicles including a fatty acylated amino acid and an oil-in-water emulsion. Interferon-&agr; is entrapped in the vesicles.

Abstract: A composition for transdermal administration of a cytokine is described. The composition includes a conjugate composed of a cytokine, such as an interferon, and at least one fatty acid moiety covalently attached to the cytokine. The conjugate has enhanced cutaneous delivery relative to the cytokine alone.

Abstract: A biphasic multilamellar lipid vesicle comprising a plurality of spaced apart lipid bilayers that include a liposome-forming component and optionally a biologically active agent entrapped within the lipid bilayers. The lipid vesicle also comprises peripheral aqueous solution compartments formed between the lipid bilayers and a central lipophilic core compartment substantially at the center of the multilamellar lipid vesicle.

Abstract: A composition for transdermal administration of an immunogen is described. The immunogen is entrapped in lipid vesicles having a oil-in-water emulsion in the central core compartment. The vesicles are administered transdermally to elicit an immune response in a subject.

Abstract: A device for the dermal and transdermal delivery of liposomes or a formulation thereof. The device comprises an applicator element carrying a containment means to store the liposomes, a liposome delivery surface for the containment means to transfer the liposomes from storage to the skin when the surface is brought into operating proximity therewith and a detachable cover means for the surface. Preferably, the device comprises a screen covering the containment means. The screen is characterized in that it is sufficiently hydrophobic to constitute a barrier for preventing passage of the liposomes when the screen is not in contact with the skin. It also has a plurality of pores of sufficient diameter to allow passage of the liposomes through the screen when the screen is in contact with the skin.
