Abstract

To improve the solubility enhancement of solid dispersion of Lopinavir by spray-drying by adding the Soluplus as polymer that is compatible with Lopinavir, was evaluated and the process used for preparation of Spray dried solid dispersion was validated and the 1:3 ratio used for preparation of solid dispersion. Dissolution tests were carried out on several spray dried solid dispersion of Lopinavir and physical mixture. The solid dispersion characterized by DSC, XRD, % Entrapment Efficiency, solubility study, drug content determination, practical yield, dissolution studies. Keyword: Lopinavir, Soluplus, Spray Drying Technique, Dissolution studies

提高洛匹那韦溶解度的颗粒工程与喷雾干燥工艺设计
为了提高洛匹那韦固体分散体的溶解度,通过添加与洛匹那韦相容的Soluplus作为聚合物,对喷雾干燥法提高洛匹那韦固体分散体的溶解度进行了评价,验证了喷雾干燥固体分散体的制备工艺,并采用1:3的比例制备固体分散体。对洛匹那韦的几种喷雾干燥固体分散体和物理混合物进行了溶出试验。采用DSC、XRD、%包封效率、溶解度研究、药物含量测定、实际产率、溶出度研究等方法对固体分散体进行表征。关键词:洛匹那韦;Soluplus;喷雾干燥技术
