摘  要:目的建立高效液相色谱-质谱法(HPLC-MS/MS)测定人血浆中舍曲林浓度,并使用该方法评价2种盐酸舍曲林制剂在中国健康人体内的生物等效性。方法采用HPLC—MS/MS梯度洗脱法测定健康志愿者单次口服盐酸舍曲林50mg后不同时间血浆中舍曲林的浓度。以去甲基托伐普坦为内标,Luna C18(50mm×2.0mm,3μm)为色谱柱。梯度洗脱条件下,采用多反应监测(MRM)方式进行定量分析,用于监测的离子质荷比分别为m/z306.1→m/z159.0(舍曲林)和m/z435.2→m/z238.1(内标去甲基托伐普坦)进行测定。结果舍曲林和内标的保留时间分别为3.0和3.2min。血浆中舍曲林检测浓度在0.210~26.8μg·L^-1线性关系良好。日内和日间RSD均〈15%。试验制剂与参比制剂血浆中舍曲林的‰。。分别为(5.25±2.61)、(5.15±2.37)11;Cmax分别为(13.4±4.51)、(13.2±5.16)μg·L^-1;t1/2分别为(27.0±4.4)、(28.9±6.2)h;AUC0~t为(408.6±157.2)、(418.3±141.0)μg·h·L^-1;AUC0~∞分别为(452.5±188.5)、(469.3±169.5)μg·h·L^-1试验制剂对参比制剂的相对生物利用度,为(97.6±18.8)%。经方差分析和双单侧t检验,主要药动学参数无差异。结论梯度洗脱HPLC-MS/MS法可用于测定人血浆中舍曲林的浓度;盐酸舍曲林片两制剂生物等效。Objective To establish a gradient elution HPLC-MS/MS method to determine sertraline hydrochloride in human plasma and its bioequivalence in healthy Chinese volunteers. Methods The plasma concentrations were determined by gradient elution HPLC-MS/MS method after a single oral dose of 50 nag reference and test preparations. The internal standard was demethylationtolvaptan, and the column was Luna C18 (50 mm ×2.0 mm, 3 μm). Under the condition of gradient elution, multiple reaction monitor (MRM) was used to detect sertraline (m/z 306.1→m/z 159.0) and demethylationtolvaptan (m/z 435.2→m/z 238.1). Results The retention time of sertraline was 3.0 min, and the retention time of demethylationtolvaptan was 3.2 min. The sertraline curve was linear at 0.210 - 26.8 μg· L ^- 1. The intraday and interday RSDs were both less than 15%. The main pharmacokinetic parameters of the test and reference preparations were as follows: tmax was (5.25 ± 2.61) and (5.15±2.37) h; Cmax was (13.4±4.51) and (13.2±5.16) μg· L ^- 1; t1/2 was (27.0±4.4) and (28.9±6.2) h; AUC0-t was (408.6 ±157.2) and (418.3± 141.0) μg · h · L ^- 1; while AUC0-∞ was (452.5±188.5) and (469.3±169.5) μg · h · L ^- 1. The relative bioavailability of the test preparations was (97.6 ±18.8)%. Conclusion The gradient elution HPLC-MS/MS method can be used to determine sertraline hydrochloride in human plasma. The test and reference preparations are bioequivalent.
