【摘要】:目的:研究唐草片對(duì)依非韋倫(EFV)在大鼠體內(nèi)藥動(dòng)學(xué)的影響。方法:采用液相色譜-串聯(lián)質(zhì)譜(LC-MS/MS)法。色譜柱為Eclipse XDB-C18,流動(dòng)相為0.1%甲酸水溶液-甲醇(20∶80,V/V),流速為0.5 ml/min,柱溫為30℃,進(jìn)樣量為10μl;采用電噴霧電離(ESI),用于定量分析的離子對(duì)依次為m/z 515.2→276.2(內(nèi)標(biāo):替米沙坦),m/z 316.0→243.9(EFV)。18只SD大鼠隨機(jī)均分為3組,分別單獨(dú)灌胃EFV(54 mg/kg,即EFV組)、同時(shí)灌胃EFV和唐草片(54 mg/kg+864 mg/kg,即EFV-0T組)、灌胃EFV 60 min后灌胃唐草片(54 mg/kg+864 mg/kg,即EFV-60T組)。于大鼠灌胃給藥前與末次給藥后0.25、0.5、1.0、2.0、3.0、4.0、6.0、9.0、12.0、24.0h于頸動(dòng)脈取血,測(cè)定不同時(shí)間血藥濃度,以DAS 2.0軟件計(jì)算藥動(dòng)學(xué)參數(shù)。結(jié)果:EFV質(zhì)量濃度在75.0~9 600.0 ng/ml范圍內(nèi)與其和內(nèi)標(biāo)物峰面積之比呈良好線性關(guān)系,精密度試驗(yàn)的RSD值均小于10%,準(zhǔn)確度為92.1%~102.0%,提取回收率為88.6%~91.0%,穩(wěn)定性試驗(yàn)的RSD均小于10%。與EFV組比較,EFV-0T組AUC0-∞、t1/2、MRT0-∞降低,CL/F提高,差異有統(tǒng)計(jì)學(xué)意義(P0.01或P0.05);EFV-60T組各指標(biāo)差異無統(tǒng)計(jì)學(xué)意義(P0.05)。各組大鼠tmax、cmax、V/F差異無統(tǒng)計(jì)學(xué)意義。結(jié)論:EFV與唐草片同時(shí)服用會(huì)降低EFV血藥濃度;當(dāng)兩藥合用時(shí),須在服用EFV 60 min后服用唐草片。
