摘要:
In the method for preparation of microspheres by in-water drying method, an iterative process is employed, which comprises emulsifying a medicament-containing polymer solution (4) containing an organic solvent in an emulsifying device (1) to form an emulsion; transferring this emulsion into a microsphere storage tank (2); introducing a part of said emulsion to a cross flow filter (3) from the microsphere storage tank; and returning a liquid passing over the cross flow filter to the microsphere storage tank (2). Since a small amount of microsphere is repeatedly produced, this process permits the downsizing and airtight closing of an apparatus therefor, and further makes it possible to freely control the production scale of microsphere.
