摘要：
An object of the present invention is to provide a method for producing a liposome preparation having excellent rapid action and excellent redispersion into aqueous medium. The present invention provides a method for producing a liposome preparation by vacuum drying wherein liposome condensed solution, which is obtained by removing solvent from liposome solution, is subjected to vacuum drying without freezing while bubbling the condensed solution or after the condensed solution is bubbled.
