摘要: 目的 研究盐酸雷尼替丁微丸胶囊和善胃得(盐酸雷尼替丁片, 葛兰素史克) 的人体药代动力学和生物等效性。方法 20 名健康志愿者按双周期随机交叉试验设计口服受试制剂盐酸雷尼替丁微丸胶囊和参比制剂盐酸雷尼替丁片, 用高效液相色谱(HPLC) 法测定血浆中雷尼替丁的浓度。结果 单剂量口服盐酸雷尼替丁微丸胶囊和盐酸雷尼替丁片后Cmax分别为1.62±0.56和1.78±0.69μg·ml-1 , t max分别为2.8±1.1 和2.6±0.8 h, AUC0-τ分别为6.69±1.46 和6.67±1.86 μg·h·ml-1 , AUC0-∞分别为7.06±1.56 和7.06±1.86 μg·h·ml-1 。受试制剂盐酸雷尼替丁微丸胶囊的相对生物利用度为103.8 %±19.1 %。结论 盐酸雷尼替丁微丸胶囊和善胃得两种制剂生物等效。

Abstract: AIM: To study the pharmacokinetic activities and bioequivalence of ranitidine capsule after oral administration in healthy volunteers.METHODS: A single administration of 300 mg test and reference ranitidine were given to 20 healthy male volunteers in randomized crossover study respectively.The HPLC was developed to determine the concentration of ranitidine in human plasma.RESULTS: The pharmacokinetics parameters after a single oral dministration of 300 mg test and reference products were as follows:Cmax were 1.62±0.56 and 1.78±0.69 μg·ml-1, t max were 2.8±1.1 and 2.6±0.8 h, AUC0-τ were 6.69±1.46 and 6.67±1.86μg·h·ml-1 , AUC0-∞ were 7.06±1.56 and 7.06±1.86 μg·h·ml-1 , respectively.The relative bioavailability of single oral administration group was 103.8 %±19.1 %.CONCLUSION: The test and reference products were bioequivalent.
