摘要:

由于阿昔洛韦水溶性高, 较难用普通高效液相色谱法测定其血浆中的药物浓度。本研究建立并验证了测定大鼠血浆中阿昔洛韦浓度的高效液相色谱方法, 并将该方法应用于与吉非替尼的药物相互作用研究中。采用Platisil ODS柱(4.6 mm × 250 mm, 5 μm, 迪马科技), 检测波长254 nm, 蛋白沉淀后再用甲基叔丁基醚萃取进行样本处理。阿昔洛韦浓度在0.2–40 μg/mL范围内具有良好的线性关系(r2 = 0.9999), 本方法批间和批内精密度均小于8%, 批间和批内准确度偏差不超过10%。该方法已成功应用于大鼠体内吉非替尼和阿昔洛韦的药物相互作用研究中。结果显示, 同时服用吉非替尼可使阿昔洛韦的吸收增加3倍, 这为临床表皮生长因子-酪氨酸酶抑制剂与阿昔洛韦的合用提供了参考。

Abstract:

The assay of acyclovir in plasma seems to be a challenge because of its high hydrophily. In our present study, a reversed-phase high-performance liquid chromatography (RP-HPLC) method for the determination of acyclovir in rat plasma was described and validated in drug-drug interaction (DDI) between gefitinib and acyclovir in rats. The analytes were separated with gradient elution on C18 column (4.6 mm × 250 mm, 5 μm), and the peaks were recorded using ultraviolet detector at a wavelength of 254 nm. Protein precipitation followed by methyl tertiary butyl ether extraction was used for sample preparation. The calibration curve was established between 0.2 and 40 μg/mL (r2 = 0.9999). The intra- and inter-day precisions were all less than 8%, and all the biases were not more than 10%. This new method was successfully applied to a DDI study between gefitinib and acyclovir in rats. Gefitinib up-regulated the absorption of acyclovir by about three times, and our findings guided the clinical co-administration of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) with acyclovir.
