DRUG-ENCAPSULATING INORGANIC MICROPARTICLE, MANUFACTURING METHOD THEREOF AND PREPARATION COMPRISING DRUG-ENCAPSULATING INORGANIC MICROPARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a nonirritating drug-encapsulating inorganic microparticle, which is easy to prepare as a preparation, is applicable to many medicinal proteins, low-molecular weight compounds and genes, can stabilize the medicinal proteins, low-molecular weight compounds and genes, and has a good sustained releasability and a good targeting effect, and to also provide a manufacturing method thereof and a preparation comprising the drug-encapsulating inorganic microparticle. SOLUTION: The drug-encapsulating inorganic microparticle is comprised of a calcium-containing inorganic microparticle which is hardly soluble in water and a biological active substance encapsulated within the microparticle.
