| 摘 要： | 利用高分子材料制备固体分散体是当前最有效最便捷的改变非水溶性药物的水溶解度和生物利用度的方法之一。为探究临床常见药用高分子材料载体的优越性和差异性，利用聚乙二醇(PEG)6000、PEG4000、聚维酮(PVP)k30、PVPk15、泊洛沙姆188等高分子材料为载体，采用熔融法、溶剂法和溶剂熔融法制备氟苯尼考固体分散体，溶出速率法验证固体分散体，比较氟为尼考原料、物理混合物及固体分散体的溶解度和累积溶出率。结果表明：几种固体分散体均可提高氟苯尼考药物的溶解度和体外溶出速率，其增溶效果为PEG6000>PEG4000>PVPk30>PVPk15>188，氟苯尼考与PEG6000配比在1∶4时溶解度和体外溶出速率均最优，是最佳配比。5种不同高分子材料制备氟苯尼考固体分散体，制备方法简便易操作、质量可控，能提高药物的溶解度，其中PEG6000增溶效果最优，可广泛应用。

| Abstract: | Preparation of solid dispersion by polymers for pharmaceuticals is one of the most effective and convenient methods to improve the solubility and bio-availability of many hydrophobic drugs. In order to investigate the differences of several carriers commonly used in clinic practice, this study took polyethyleneglycol (PEG)6000, and PEG4000, polyvinyl pyrrolidone (PVP) k30, PVPk15 and poloxamer 188 as carriers and prepared florfenicol solid dispersions (SDs) by melting method and solvent-melting method with 5 different polymers for pharmace-uticals, and validated the SDs by dissolution rate method. Solubility and cumulative dissolution rate of florfenicol(FF), physical mixture and SDs were measured and analyzed comparatively. The results showed that the solubility of SDs was raised compared with FF itself. Meanwhile, the efficiency of solubilization was PEG6000>PEG4000>PVPk30>PVPk15>188. Especially, PEG6000 polymers could enhance the solubility remarkably. The best matching was FF:PEG6000 (1∶4). Conclusion, these methods for SDs preparation were simple, convenient, and the quality of SDs can be controlled easily. Among them, especially PEG6000 has the best solubilization effect and can be widely applied. |
