Abstract
目的:以泊洛沙姆407(P407)和泊洛沙姆188(P188)为组合基质,添加生物黏附剂卡波姆(Cabopol)以及促渗透剂氮酮(Azone)制备温敏型布洛芬(IBU)缓释液体栓剂,考察液体栓释药的体内外相关性。方法:以凝胶温度、凝胶强度、生物黏附力和液体栓剂体外释放度为指标进行体外筛选;经比格犬直肠给药测定动物体内药物释放曲线进行体内筛选;用3P97程序计算药动学参数。结果:布洛芬体外释放结果符合零级模式,R2>0.9时,体内药物释放出现平台,显示了良好的体内外相关性;药动学研究结果表明,体内过程为一室模型,药动学参数为tmax=3.551 h,Cmax=21.483μg.mL-1,t1/2(Ke)=2.740 h,AUC0→∞=210.850μg.mL-1.h,MRT=7.670 h。结论:所制备的布洛芬液体栓剂具有良好的缓控释特征。
