摘 要:目的:研究马来酸替加色罗片在中国健康受试者中的药代动力学特征。方法:采用LC-MS法研究单次和连续口服马来酸替加色罗片的药动学特征。结果:健康受试者分别单次口服6、12、18 mg马来酸替加色罗片后,药-时曲线符合二室开放模型,主要药代动力学参数t_(max)为(2.2±1.0)、(1.3±0.5)、(1.3±0.4)h;C_(max)为(3.4±0.4)、(8.5±1.4)、(12.0±2.4)ng/mL;t_(1/2α)为(5.5±6.4)、(4.6±5.6)、(2.0±2.0)h;t_(1/2β)为(16.2±2.4)、(15.2±1.8)、(14.9±2.0)h;AUC_(0→48)为(53±9)、(96±29)、(135±54)ng·h·mL^(-1);AUC_(0→∞)为(64±12)、(108±33)、(158±60)ng·h·mL^(-1);MRT为(16.3±1.0)、(14.8±1.1)、(14.6±0.7)h。C_(max)、AUC_(0→48)和AUC_(0→∞)在6~18 mg内与给药剂量呈线性关系。统计分析结果还表明t_(max)、t_(1/2α)、t_(1/2β)和MRT在上述不同剂量组间无统计学差异(P>0.05)。连续给药3 d后血药浓度达稳态,达到稳态后的t_(max)、C_(ss,max)、C_(ss,min)、C_(ss,avg)、DF值分别为(1.5±0.4)h、(8.1±1.3)、(2.6±0.7)、(4.4±0.8)ng/mL、(126±16)%。在相同剂量下,C_(max)、AUC_(0→48)、AUC_(0→∞)和t_(1/2β)等参数值较文献报道高。结论:在中国健康受试者中马来酸替加色罗片的体内过程符合二室开放模型,在6~18 mg范围内具有线性动力学特征。AIM: To study the pharmacokinetics of Tegaserod Hydrogen Maleate Tablet in healthy Chinese volunteers. METHODS: The volunteers received a single 6, 12 or 18 mg dose of tegaserod orally, respectively. Tegaserod in plasma was determined by LC-MS. RESULTS: The pharmacokinetics of tegaserod conformed to a 2-compartment open model after single oral dose (6, 12 and 18 mg). The tmax was (2.2± 1.0), (1.3±0.5), (1.3±0.4) h; Cmax was (3.4±0.4), (8.5± 1.4), (12.0± 2.4) ng/mL; t1/2α was (5.5 ± 6.4), (4.6± 5.6), (2.0±2.0)h; t1/2β was (16.2±2.4), (15.2± 1.8), (14.9±2.0) h; AUC0→48 was (53±9), (96± 29), (135±54) ng·h·mL^-1; AUC0→∞ was (64± 12), (108±33), (158±60)ng·h·mL^-1; MRTwas (16.3 ±1.0), (14.8± 1.1), (14.6±0.7) h. The Cmax、 AUC0→48 and AUC0→∞ were correlated linearly with dosage within 6 - 18 mg. The statistical analysis indicated that the tmax, t1/2α, t1/2β and MRT had no significant differences among different groups. The plasma concentration of tegaserod reached steady state after successive administration of 3 days, and the tmax, Css、max, Css、min,Css,avg, DF were (1.5±0.4) h, (8.1±1.3), (2.6±0.7), (4.4 ± 0.8) ng/mL, (126 + 16) % respectively. The Cmax, AUC0→48, AUC0→∞ and t1/2β were apparently more than those reported in other population. CONCLUSION: The pharmacokinetics of tegaserod hydrogen maleate tablet in healthy chinese volunteers can be described by a two compartment model and has a linear dynamics character within the range of 6- 18 mg.
