Abstract
Provided are a liposome composition in which an osmotic pressure of an inner water phase is 2-fold to 8-fold relative to the osmotic pressure of an outer water phase, and which encapsulates a water-soluble drug in a dissolved state, and also exhibits excellent preservation stability; and a method for producing the same. According to the present invention, it is possible to provide a liposome composition, including liposomes obtained from lipids dissolved and emulsified in an organic solvent, 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 each of the liposomes encapsulates a water-soluble 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; and a method for producing the same.
