    Abstract: Provided are a liposome composition which has a practically required long-term preservation stability, and which has a release rate of a drug on the order of several tens of hours due to releasability of a drug being able to be suitably controlled by rendering an inner water phase hyper-osmotic; and a method for producing the same. According to the present invention, it is possible to provide a liposome composition, including liposomes each of which has an inner water phase and an aqueous solution which constitutes an outer water phase and in which the liposomes are dispersed, in which the content of cholesterols is 10 mol % to 35 mol % with respect to the total amount of lipid components in the liposome composition, and each of the liposomes encapsulates a drug in a dissolved state, and an osmotic pressure of the inner water phase is 2-fold to 8-fold relative to the osmotic pressure of the outer water phase.
