一、导言简单的微囊制备是在高温下将药物细粒分散子亲水性或疏水性液体中,然后降至室温,让其固化。当将含有药物的热的液体载体通过毛细管滴入到不溶解载体物质的冷溶剂中时,就能得到近似球体的小颗粒。一般来说,微囊的制备方法对于需要包裹的有 I. INTRODUCTION Simple microcapsule preparation is to disperse a drug in a hydrophilic or hydrophobic liquid at high temperatures and then to room temperature to allow it to cure. When a drug-containing hot liquid carrier is dropped through a capillary tube into a cold solvent that does not dissolve the carrier material, small particles that approximate the sphere can be obtained. In general, the preparation of microcapsules need to package there
