摘要 以烟酸和辛伐他汀为模型药物制备复方双层缓释片,并评价其体外释放特性。采用双周期双交叉给药方案,LC-MS/MS法同时测定自制制剂和市售制剂中烟酸和辛伐他汀的血药浓度,对6只Beagle犬进行了药代动力学和生物利用度的初步研究。自制制剂和市售制剂给药后烟酸的cmax分别为(6.43±0.80)和(6.38±0.47)μg/mL,tmax分别为(2.80±1.00)和(2.50±1.00)h,AUC分别为(30.16±4.51)和(27.49±4.04)μg.h/mL;辛伐他汀的cmax分别为(38.65±1.71)和(40.54±2.33)ng/mL,tmax均为(1.50±0.40)h,AUC分别为(118.76±11.83)和(115.76±5.46)ng.h/mL。结果表明两种制剂中烟酸和辛伐他汀的AUC,cmax和tmax都等效,说明自制制剂和市售制剂在Beagle犬体内具有生物等效性。 Compound nicotinic acid extended-release and simvastatin immediate-release double-layer tablets were developed and their in vitro release characteristics were evaluated.The LC-MS/MS method was established for the determination of the concentration of nicotinic acid and simvastatin in blood and investigate the pharmacokinetics and relative bioavailability in 6 Beagle dogs with the double-period and double-crossover dosage regimen.After oral administration of the test and reference tablets,cmax of nicotinic acid was(6.43±0.80) and(6.38±0.47) μg/mL;tmax was(2.80±1.00) and(2.50±1.00) h;AUC was(30.16±4.51) and(27.49±4.04) μg ·h/mL,respectively.cmax of simvastatin was(38.65±1.71) and(40.54±2.33) ng/mL;tmax was(1.50±0.40) and(1.50±0.40) h,AUC was(118.76±11.83) and(115.76±5.46) ng ·h/mL,respectively.Statistical analysis indicated that AUC,cmax and tmax of test preparations were equivalent to reference preparations.So it is bioequiavailability between the test and reference preparations in Beagle dogs.
