    Abstract: A method for encapsulation of antineoplastic agents in liposomes is provided, having preferably a high drug:lipid ratio. Liposomes may be made by a process that loads the drug by an active mechanism using a transmembrane ion gradient, preferably a transmembrane pH gradient. Using this technique, trapping efficiencies approach 100%, and liposomes may be loaded with drug immediately prior to use, eliminating stability problems related to drug retention in the liposomes. Drug:lipid ratios employed are about 3-80 fold higher than for traditional liposome preparations, and the release rate of the drug from the liposomes is reduced. An assay method to determine free antineoplastic agents in a liposome preparation is also disclosed.

  • Patent number: 5616330
    Abstract: This invention is directed to a composition of a taxine in a stable oil-in-water emulsion for intravenous administration. The invention also relates to a method for incorporating a taxine into an oil and making a stable oil-in-water emulsion.The composition includes a taxine, an oil, water and a surfactant. In a preferred embodiment, the taxine is taxol, the oil is safflower oil and the surfactant is lecithin, The taxine is incorporated into the oil by dissolving the taxine in a solution of an oil and a taxine co-solvent, such as isopropanol, for example. The co-solvent then is removed to form a solution of the taxine in oil. This solution may be dispersed in water with a surfactant to form a stable oil-in-water emulsion for intravenous administration.

  • Patent number: 5616341
    Abstract: A method for encapsulation of antineoplastic agents in liposomes is provided, having preferably a high drug:lipid ratio. Liposomes may be made by a process that loads the drug by an active mechanism using a transmembrane ion gradient, preferably a transmembrane pH gradient. Using this technique, trapping efficiencies approach 100%, and liposomes may be loaded with drug immediately prior to use, eliminating stability problems related to drug retention in the liposomes. Drug:lipid ratios employed are about 3-80 fold higher than for traditional liposome preparations, and the release rate of the drug from the liposomes is reduced. An assay method to determine free antineoplastic agents in a liposome preparation is also disclosed.

  • Patent number: 5580562
    Abstract: A Tripterygium wilfordii Hook F preparation having an improved LD.sub.50 in mice, an improved therapeutic activity:toxic index ratio and a lower amount of triptolide as compared to previous preparations is disclosed. The LD.sub.50 in mice of the T. wilfordii preparation is greater than about 860 mg/kg, the therapeutic activity:toxic index ratio is greater than about 2.6.times.10.sup.-3, and the amount of triptolide is less than about 1.3 .mu.g/mg. The preparation is useful for immunosuppression, in particular, the suppression of primary antibody response and suppression of autoimmune disease and for the treatment of rheumatoid arthritis.

  • Patent number: 5578583
    Abstract: Microemulsions, similar in chemical composition to the lipid portion of low density lipoprotein (LDL), but not containing the protein portion, can be used as vehicles for the delivery of chemotherapeutic or diagnostic agents to neoplastic cells, while avoiding normal cells. When these artificial microemulsion particles are injected in the bloodstream or incubated with plasma, they incorporate plasma apolipoproteins on to their surface. The microemulsions can then be incorporated into cells via receptors for LOL and deliver molecules which are incorporated in the core or at the surface of the microemulsion.
