Abstract: One aspect of the disclosure relates to a new fom1 of lipid-complexed active platinum compound, which allows for high concentrations of platinum compound in the composition. For example, the concentration of cisplatin in the composition is higher at room temperature, e.g., about greater than 1.2 mg/mL, compared to 1 mg/mL in aqueous solution. In one embodiment, the present invention is directed to a composition comprising a lipid-complexed active platinum compound, wherein the complex has a lipid to drug (L/D) ratio of less than about 1 by weight, e.g. about 0.10 to 1, wherein the lipid-complexed active platinum compound comprises at least one lipid and at least one active platinum compound. In other embodiments, wherein lipid-complexed active platinum compound has an average volume-weighted diameter of about 0.5 to about 20 microns. In still other embodiments, the composition further comprises a liposome.

Abstract: An inhalation system comprising an antiinfective agent in particle form, the antiinfective agent being directed toward prevention and treatment of intracellular infection, and an inhalation device, and a method of use of the system.

Abstract: A method of preparing a liposomal bioactive agent comprising infusing an lipid-ethanol mixture with an aqueous or ethanolic solution of the bioactive agent at a temperature below the phase transition of at least one of the lipid components of the lipid and compositions produced by the method of the invention.

Abstract: This invention provides a method of preparing large liposomes with high entrapment capacity for pharmaceutical substances. The method generally entails infusing a lipid/alcohol solution directly into an aqueous polymer solution. The resulting liposome, which may be incorporated with a pharmaceutical substance, typically consists of multilamellar vesicles that have an average size of about 1 to about 8 microns. The ratio of lipid to polymer, average molecular weight of the polymer, polymer concentration, ionic strength, and temperature of incubation are variables disclosed herein to control liposome size and incorporation of components and pharmaceutical substances.
