摘要: Polylactic acid microspheres having an average particle diameter of about 0.1 to 10 .mu.m which are produced from solution containing a physiologically active substance by the solvent-evaporation drying process. The microspheres are produced by emulsifying the solution in a non-solvent by the aid of ultrasonic wave. The microspheres produce a sustained release effect of the physiologically active substance.
