Abstract: An object of the present invention is to provide a liposome composition and a pharmaceutical composition, which exhibit a high AUC. Provided are a liposome composition including a hydrophilic polymer-modified diacylphosphatidylethanolamine, a dihydrosphingomyelin, and cholesterols as components of a liposome membrane, in which the liposome composition encapsulates a drug, an inner water phase thereof contains ammonium sulfate, and a molar ratio of sulfate ions in the inner water phase to the drug in an entire water phase is 0.36 or more; and a pharmaceutical composition including the liposome composition.

Abstract: Disclosed herein are a method for producing a liposome which is capable of reducing the facility costs and also capable of rapid desolvation, and an apparatus for producing a liposome which is for use in the above-mentioned method. Provided is a method for producing a liposome, including a stirring step of stirring a mixed liquid containing an oil phase in which at least one lipid is dissolved in an organic solvent and a water phase, and an evaporating step of evaporating an organic solvent from the mixed liquid, in which the condensed organic solvent is removed by passing a gas having a temperature not higher than the dew point of the solvent in the evaporating step.

Abstract: Disclosed herein are a method for producing a miniaturized liposome on a large production scale, and an apparatus for producing a liposome which is to be used in the above-mentioned method. Provided is a method for producing a liposome, including a step of stirring a mixture containing an oil phase in which at least one lipid is dissolved in an organic solvent and a water phase in a first tank of an apparatus having the first tank and a circulation path, in which the ratio of the capacity of the circulation path to the total capacity of the tank and the circulation path is 0.4 or less and/or the time required for the mixture to return to the first tank after being discharged therefrom is within 2.0 minutes.

Abstract: An object of the present invention is to provide a liposome and a liposome composition in which release of a drug in blood is suppressed during accumulation of the liposome and the liposome composition in a target site such as a tumor and the drug is rapidly removed after the liposome and the liposome composition are sufficiently accumulated. According to the present invention, there is provided a liposome containing at least a phospholipid to which a hydrophilic polymer is bonded, a phospholipid having a negative charge within a range of a pH of 6 to 8, and a phospholipid which is electrically neutral within a range of a pH of 6 to 8, in which an average carbon chain length of the phospholipid to which the above-described hydrophilic polymer is bonded is shorter than an average carbon chain length of the above-described phospholipid which is electrically neutral within a range of a pH of 6 to 8.
