MEDICAMENT IN FINE PARTICLE FORM, METHOD AND DEVICE FOR PREPARATION THEREOF, AND AGENT FOR PARENTERAL INJECTION AND METHOD FOR PRODUCTION THEREOF

摘要

In a method for finely pulverizing an organic compound 5 in treatment target liquid 2 to manufacture fine particles of the organic compound 5, a laser beam having a wavelength which is longer than the light absorption band of the organic compound 5 or corresponds to an absorption wavelength of solvent is irradiated to the treatment target liquid 2 to finely pulverize the organic compound 5, thereby manufacturing fine particles of the organic compound 5. According to this manufacturing method, the fine particles can be manufactured with sufficiently preventing photochemical reactions of the organic compound 5 in the treatment target liquid 2. Accordingly, a fine particle manufacturing method and apparatus that can manufacture fine particles while sufficiently preventing photochemical reactions in the organic compound, fine particles, and injectable agent and a manufacturing method for the injectable agent can be implemented. <IMAGE>
