Abstract
一种受控释放组合物,包括由硫氮酮或其药学
上可接受的盐和可选的成球剂组成的球状核,所述核
被一种受控释放材料涂覆。如果加入成球剂的话,最
好选用微晶纤维素。乙基纤维素是优选的受控释放
涂层。受控释放涂层最好包含增塑剂、表面活性剂和
胶粘改性剂。
Description
本发明所用的适当的药学上可接受的盐包括药学上可接受的酸加成盐。特别优选盐酸盐。
本发明的受控释放药用组合物能够在较长时间内缓慢释放药物,并且在该时间内延长药物作用时间以达到常规药物传送的效果。
“球状”一词是药学领域的常用词,它是指直径为0.1mm~2.5mm;尤其是0.5mm~2mm的球状粒子。
成球剂可以是任何适当的药学上可接受的材料。它可以与活性成分一起成球以形成球状核。优选的成球剂是微晶纤维素,所用的微晶纤维素可以是,例如阿维塞尔PH107或阿维塞尔PH102(商品名,FMC公司)。一般来说,当存在成球剂时,它占球状核的1%~60%(重量),最好药15%~40%(重量)。
球状核还可含有其它药学上可接受赋形剂和稀释剂。使之易于成球,例如用糖(如蔗糖、右旋糖、麦芽糖或乳糖)或糖醇(例如甘露醇、木糖醇或山梨糖醇)。在球状核中还可含有着色剂。
球状核最好是涂覆允许硫氮
酮在水性介质中控制速率释放的膜,适宜的涂膜材料可包括水不溶蜡和聚合物,例如聚甲基丙烯酸酯(例如商标为Eudragit的聚合物)或优选水不溶纤维素,特别是乙基纤维素。这膜涂层还可含水溶性聚合物,例如聚乙烯吡咯烷酮或最好是水溶性纤维素,例如羟丙基甲基纤维素和羟丙基纤维素。应当理解,水不溶材料与水溶性材料的比率取决于所要求的释放速度和所选村料的溶解度,水溶性聚合物与水不溶聚合物的比率以1∶20至1∶2为佳。受控释放涂层优选包括一种或多种本领域的常规增塑剂,例如酞酸二乙酯,但最好是癸二酸二丁酯;表面活性剂,例如山梨聚糖三油酸酯、山梨聚糖单月桂酸酯或优选多乙氧基醚80(商标为Tween80)和胶粘改性剂,例如滑石粉或优选胶质无水硅石。
当存在增塑剂时,其含量将取决于所选的特定增塑剂,一般,增塑剂的量为受控释放膜涂层的1%至25%(重量)。当存在表面活性剂时,其适宜存在量为受控膜涂层的1%至25%(重量)当存在胶粘改性剂时,其存在量也以受控释放膜涂层的1%至25%(重量)为宜。
优选的受控释放膜涂层包括50%至95%乙基纤维素,5%至15%胶质无水硅石,5%至15%癸二酸二丁酯和5%至15%多乙氧基醚80(商标为Tween 80)。
采用传统涂覆方法例如流化床或槽式涂覆,可在含硫氮
酮的球状核的表面形成受控释放涂膜层。该涂层材料可应用溶液或悬浮液,适宜的溶剂系统包括水、二氯甲烷、乙醇、甲醇、异丙醇和丙酮及其混合物。涂覆溶液或悬浮液优选含2%至60%(重量)、最好含2%至20%(重量)涂覆材料。
受控释放涂覆材料的用量取决于所要求的释放速率,但是一般为受控释放涂覆球体的1%至25%(重量),最好为2%至8%(重量)。
(b)挤压成粒混合物,得到挤出物;
(c)将挤出物成球,直至形成球状核;
(d)干燥球状核;并且
(e)膜涂覆球状核。
采用传统制药技术可将本发明组合物填充制成胶囊或压制成片剂。
为了更好地理解本发明,给出下述实施例,仅为说明而已。
