摘要:
This disclosure relates to cyclodextrin-based drug delivery agents that comprise a cyclodextrin moiety covalently linked to a moiety of a gemini surfactant. Pharmaceutical compositions comprising the drug delivery agent and a therapeutic agent are also disclosed.
摘要:
A biphasic lipid vesicle composition for treating cervical displasia by intravaginal delivery. The composition includes a suspension of lipid-bilayer vesicles having entrapped therein, an oil-in-water emulsion, human interferon alpha-2b and L-methionine, the composition having an interferon alpha-2b specific activity of between about 1-10 MIU (million international units) per gram composition, and between 0.01 to 0.5 weight percent L-methionine. In the treatment method, the composition is administered at a dose of between about 1-20 MIU interferon alpha-2b, and this dose is administered at least 3 days/week, for a period of at least 4 weeks.
摘要:
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.

摘要:
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.
摘要:
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.

摘要:
The current application relates to a method for solubilizing (dispersing and debundling) of carbon nanotubes using a gemini surfactant, which has head groups and a spacer linking the head groups. The dispersion of nanotubes produced by said method can be used as a delivery system for biologically active agents to an organism.
