摘要
A novel microparticle preparation comprising microparticles of a polymer which contain a drug and are coated with a film of an agent for preventing aggregation of the microparticles is disclosed. The preparation is produced by spraying a solution of a polymer containing a drug and an aqueous solution of an agent for preventing aggregation of the microparticles separately from different nozzles and contacting them with each other in a spray dryer.
