Abstract

PURPOSE: To obtain a spherical particle preparation capable of efficiently forming and having excellent sustained release of medicine in the resultant preparation, by using an ethanol-insoluble and water-soluble high polymer substance and ethanol-soluble high polymer substance as a base.
CONSTITUTION: The aimed spherical particle preparation consisting of 15W90wt.%, preferably 20W55wt.% ethanol-insoluble and water-soluble high polymer substance (e.g. hydroxypropylmethylcellulose or PVA), 5W65wt.%, preferably 8W30wt.% ethanol-soluble with polymer substance (e.g. hydroxypropyl cellulose or polyvinyl pyrrolidone) and residual amount of medicine and an necessary added additive (e.g. diluent, surfactant or pigment), provided that total of both high polymer substances is 20W95wt.%, preferably 30W65wt.% and having 0.5W2mm, especially 0.8W1.5mm particle size.
