Abstract:
A method of producing water-insoluble anti-cancer drug in the form of particulates, the method including preparing a water-insoluble anti-cancer drug having at least one multiple bond in the structure, and irradiating said water-insoluble anti-cancer drug with a laser beam having a wavelength of a low absorption portion in the vicinity of the foot of an absorption curve on the long wavelength side within the absorption band until said water-insoluble anti-cancer drug is formed into particulates having an average particle diameter of 50 to 200 nm.
