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、18mg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tmax为(2.2±1.0)、(1.3±0.5)、(1.3±0.4)h; Cmax为(3.4±0.4)、(8.5±1.4)、(12.0±2.4) ng/mL;$t_{\frac{1}{2}α}$为(5.5±6.4)、(4.6±5.6)、(2.0±2.0) h; $t_{\frac{1}{2}β}$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。Cmax、$AUC_{0→48}$和$AUC_{0→∞}$在6~ 18mg内与给药剂量呈线性关系。统计分析结果还表明tmax、$t_{\frac{1}{2}α}$、$t_{\frac{1}{2}β}$和MRT在上述不同剂量组间无统计学差异(P>0.05)。连续给药3d后血药浓度达稳态,达到稳态后的tmax 、Css,max、Css,min 、Css,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,Cmax、$AUC_{0→48}$、$AUC_{0→∞}$和$t_{\frac{1}{2}β}$等参数值较文献报道高。结论: 在中国健康受试者中马来自交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。

Abstract: AIM: To study the phamnacokinetics of Tegaserod Hydrogen Maleate Tablet in healthy Chinese volunteens, METHODS: The volunteers received a single 6, 12 or 18 mg dose of tegaserod orally, respectively. Te-gasenxl in plasma was detemined by LC-MS.RE-SULTS: The pharmacok inetics of tegaserod confomed toa 2-compartment open moolel 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 (3.4±0.4), (8.5±1.4),(12.0±2.4) ng/mL; $t_{\frac{1}{2}α}$ was (5.5 ±6.4), (4.6 ±5.6), (2.0±2.0) h; $t_{\frac{1}{2}β}$ was(16.2±2.4), (15.2±1.8), (14.9±2.0) h; $AUC_{0→48}$ was (53±9), (96±29), (135±54) ng·h·mL-1; $AUC_{0→∞}$ was (64±12),(108±33), (158±60) ng·h·mL-1; MRT was (16.3±l.0), (14.8±1.1), (14.6±0.7) h. The Cmax、$AUC_{0→48}$ and $AUC_{0→∞}$ were orelated linearly with dosage within 6-18 mg. The satistical unalysis indicated that the tmax, $t_{\frac{1}{2}α}$, $t_{\frac{1}{2}β}$ and MRT had no significant differences among different groups.'The plasma concentration of tegaserod reached steady state after successive adminis-trationof 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±10.8) ng/mL, (126±16) % respectively. The Cmax、$AUC_{0→48}$、$AUC_{0→∞}$ and $t_{\frac{1}{2}β}$ were apparently more than those reported in other population. CONCLUSION: The phamnacokinetics of tegaserod hydrogen maleate tabletin healthy chinese volunteers can he described by a two compartment model and has a linear dlynamics character within the range of 6-18 mg.
