摘要: 目的: 研究小剂量(0.05 mg 和 0.1 mg)的盐酸纳美芬注射液在中国健康受试者体内的药代动力学。方法: 采用双周期两剂量自身随机交叉的试验设计。12名健康受试者随机单次静脉注射盐酸纳美芬 0.05 mg 和 0.1 mg,采用 LC-MS/MS测定血浆中的药物浓度,以DAS 2.0 软件计算其药动学参数。结果: 健康受试者单次静注不同剂量 0.05 mg 和 0.1 mg 盐酸纳美芬后,纳美芬的主要药代动力学参数Cmax分别为(203±99)和(488± 350) ng/L;AUC0-8分别为(177±94)和(480±194)ng·L-1·h;AUC0-∞分别为(282±134)和(649±247) ng·L-1·h;Tmax分别为(0.08±0.07)和(0.12±0.14) h;t1/2分别为(2.0±1.1)和(2.8±1.2) h。结论: 注射用的盐酸纳美芬在健康人体内的药代动力学符合二房室模型特征,在静注 0.05~0.1 mg 的范围内体内过程符合线性动力学特征。

Abstract: AIM: To study the pharmacokinetics of minidose Nalmefene hydrochloride in healthy Chinese volunteers. METHODS: In a randomized crossover trial, 12 healthy Chinese subjects received Nalmefene hydrochloride 0.05 and 0.1 mg by intravenous injection.The concentration of Nalmefene in human plasma was determined by LC-MS/MS method and its pharmacokinetic parameters were calculated by DAS 2.0. RESULTS: The main pharmacokinetic parameters of Nalmefene after a single intravenous administration dose of 0.05 and 0.1 mg Nalmefene hydrochloride were as follows: Cmax were (203±99) and (488±350) ng/L; AUC0-8 were (177±94) and (480±194) ng·L-1·h; AUC0-∞ were (282±134) and (649±247) ng·L-1·h; Tmax were (0.08±0.07) and (0.12±0.14) h; t1/2 were(2.0±1.1) and (2.8±1.2) h, respectively. CONCLUSION: The pharmacokinetics of minidose Nalmefene hydrochloride in healthy Chinese volunteer was agreement with the two-compartment mode characteristics and linear kinetics under the intravenous injection dose of 0.05 to 0.1 mg.
