μM)用于分离分析物,并将柱温度保持在30°C。选择西他列汀作为内标。0.02%甲酸水溶液(A)和甲醇 - 乙腈(B)用作梯度洗脱的移动相,流速为0.3 mL/min。洗脱程序如下:20%B(0-0.1分钟),80%B(0.1-0.3分钟),80%B(0.3-2.0分钟)和20%B(2.1-3.0分钟)。在带电喷雾源的正电离模式下使用多个反应监测仪(MRM),以检测吡格列酮(357.1⟶134.1),omarigliptin(399.2⟶153.0)和西塔甘列汀(408.2⟶235.0)。吡格列酮和omarigliptin的线性范围分别为5-2000 ng/ml和10–4000 ng/ml。在相应的线性范围中表现出良好的线性关系(
r ≥ 0.9944). The bioanalytical method was validated, and the selectivity, linearity, sensitivity, accuracy, precision, stability, recovery, and matrix effect were acceptable. The validated method was then successfully applied to pharmacokinetic study of pioglitazone combined with omarigliptin in rats. Results suggested that the combination of the two drugs had little effect on the pharmacokinetic parameters of each other in rats.
