METHOD FOR PRODUCING MICROGRANULATED PARTICLE

摘要

The present invention relates to a method for producinga microgranulated particle having particle size of not morethan 0.2 mm, wherein a fine powder with the average particlesize of not more than 10 µm, which is being agitated,tumbled or fluidized, is granulated, with a solutioncontaining a binder alone or a binder and a surfactant beingsprayed onto the surface thereof.The present invention allows to produce pharmaceuticalpreparations for poorly soluble and poorly absorbable drugsand preparations requiring a high content of the activeingredient. Also, it can provide an easy-to-handle powderymicrogranulated particle in the field of food andfertilizers.
