    摘要: The present invention relates to a liposome having a phospholipid bilayer and a hydrophilic core, wherein the phopspholipid bilayer contains D-alpha tocopheryl polyethylene glycol 1000 succinate (TPGS). The liposomes are first prepared by solvent injection and extrusion method, and then drug loading by ammonium sulfate gradient. The TPGS in the liposome composition can prolong the circulation time of liposomes and thus increase the chance for the drug composition to enter target sites so as to improve the efficiency of drug delivery.

    摘要: The present invention relates to a composition and a method for preparing a liposome, the liposome including a lipid bilayer and an aqueous core contains a hydrophobic or a hydrophilic drug and a component—Vitamin E derivative (d-α tocopheryl polyethylene glycol 1000 succinate; TPGS). TPGS is able to increase the encapsulation efficiency of drug in liposome as well as to enhance the stability of drug in liposomes. Such liposome is capable to increase the skin permeation of drugs. The preparation method comprises the following steps: (1) adding the drug to a Vitamin E derivative solution to form a mixture; and (2) adding at least one phosphatidyl choline to the mixture, after hydration from either sonication or homogenization.

    摘要: A method for preparing polymeric microsphere by an aqueous two phase emulsion process. A first polymer aqueous solution is provided and the first polymer includes a functional group capable of forming cross-linking. A second polymer aqueous solution is provided, which is acidic and miscible with the first polymer aqueous solution. The first and second polymer aqueous solutions are mixed and stirred to form an emulsion, such that the first polymer solution forms a dispersed phase in a continuous phase of the second polymer solution. The dispersed phase includes a plurality of the first polymeric microsphere, and a solidification film formed by cross-linking of the functional group constitutes a microsphere surface. Finally, the first polymeric microsphere are separated out.
