    • 摘要: Objective: To establish a rapid and accurate method for the determination of sitafloxacin in hu-man urine by means of HPLC-MS/MS. Methods: The urine was treated with methanol, and the supernatant was analyzed by an HPLC-MS/MS method. Ten subjects were recruited in a randomized crossover test. Each one had single oral sitafloxacin granule 50 mg when fasting and postprandial, with a cleaning period of 5 days. All urine samples of the subjects were collected on the two periods, before administration (0 h) and after ad-ministration of 0-3, 3-6, 6-12, 12-24, 24-36, 36-48, 48-60 h, sitafloxacin contents were analyzed and the cu-mulative excretion and cumulative excretion rates were calculated. Results: The linear range for the detection of urine sitafloxacin was 0.250-200μg·mL-1, and the limit of quantification was 0.250μg·mL-1. Prototype drug was detected 3 h after oral administration in subjects' urine, the urine excretion was almost complete in 36 h, the cumulative excretion was about 35 mg and the cumulative excretion rate was about 70%. Conclusion: The established method is simple, reliable. It can be used for the determination of urine sitafloxacin and its urinary excretion in population.%目的:建立灵敏、快速、准确的人尿液中西他沙星浓度的HPLC-MS/MS检测方法,并将其用于测定健康受试者口服西他沙星颗粒剂后的尿药排泄。方法:尿液经甲醇处理后,取上清液进行HPLC-MS/MS法分析。10例受试者,每例空腹和餐后(随机交叉)单次口服西他沙星颗粒剂50 mg,经5天的清洗期后将两式受试者对调,两周期分别收集给药前(0 h)及给药后0~3、3~6、6~12、12~24、24~36、36~48、48~60 h各时间段的所有尿液并分析,计算西他沙星在尿液中的累计排泄量和累积排泄率。结果:西他沙星尿液的线性范围为0.250~200μg·mL-1,定量限为0.250μg· mL-1。健康受试者口服西他沙星颗粒剂后3 h即能检测到原型药物,36小时内经尿液排泄基本完全,累积排泄量约为35 mg,累积排泄率约为70%。结论:所建立的方法简便、可靠,可用于人口服西他沙星颗粒剂后药物尿液浓度的测定及其尿药排泄研究。

    • 摘要: OBJECTIVE:To establish the method for the determination of mildronate in human plasma and urine,and to study the pharmacokinetic characteristics in healthy volunteers. METHODS:After precipitating plasma and urine sample,LC-MS/MS method was adopted. Dikma Diamonsil C18 column was used with mobile phase consisted of methanol-water(containing 0.2% for-mic acid,0.3% ammonium acetate)(31∶69,V/V)at the flow rate of 0.6 ml/min. ESI was adopted in MRM mode,by using nega-tive ion. The ion for quantitative analysis were m/z 147.10→58.20 (mildronate) and m/z 152.00→110.10 (internal standard,acet-aminophen). The pharmacokinetic parameters of mildronate with single administration and multiple administration were calculated by using DAS 2.1 software and compared. RESULTS:The linear range of mildronate in plasma were 0.02-20 ng/ml(r=0.999 3) and in urine were 0.05-40 ng/ml(r=0.998 2). The lowest limits of quantitation were 0.02 and 0.05 ng/ml. Precision and recovery met the requirements of biological specimen determination,and endogenous impurities hadn’t effect on the determination. The main pharmacokinetics parameters of low-dose,medium-dose and low-dose(250,500,750 mg)of mildronate in plasma with single ad-ministration were as follows:t1/2 were(3.39±0.81),(5.52±0.57)and(5.32±0.96)h;tmax were(0.80±0.45),(1.38±0.43)and (1.10±0.36)h;cmax were(4.17±1.46),(8.08±1.04)and(15.04±1.86)ng/ml;AUC0-36 h were(24.55±5.81),(45.50±7.07)and (85.60 ± 13.09)ng·h/ml. In the dose range,cmax,AUC0-36 h h had a linear relationship with dose (R2 were 0.974 5 and 0.968 3). The main pharmacokinetic parameters of low-dose of mildronate with multiple administration after keeping stable were as follows:cmin was(0.28 ± 0.10)ng/ml;AUCs was(38.78 ± 4.18)ng·h/ml;cs was(1.62 ± 0.17)ng/ml;DF was(3.81 ± 1.14);t1/2 was(6.17 ± 1.46)h;tmax was(1.20 ± 0.33)h;cmax was(6.46 ± 1.96)ng/ml;AUC0-36 h was(40.33 ± 4.65)ng·h/ml;accumulation factor of cmax and AUC were(1.73±0.90)and(1.64±0.40). Compared with single administration,t1/2,cmax and AUC of mildronate with multiple admin-istration after keeping stable all changed,and tmax had no signifi-cant difference. After single administration,26 h accumulative excretion rate of those groups were (0.004 009 ± 0.001 1)%, (0.004 026±0.001 01)% and(0.003 858±0.000 68)% respec-tively. CONCLUSIONS:Established method is sensitive,accurate and specific,and suitable for the determination of mildronate concentration in human plasma and urine and pharmacokinetics study. Mildronate capsule shows certain accumulation effect in healthy volunteers,and linear pharmacokinetic characteristics.%目的:建立测定人血浆、尿液中米屈肼浓度的方法,研究其在健康人体内的药动学特征。方法:血浆、尿液样品经沉淀法处理后,采用液相色谱-串联质谱(LC-MS/MS)法进样测定。色谱柱为Dikma Diamonsil C18,流动相为甲醇-水(含0.2%甲酸、0.3%醋酸铵)(31∶69,V/V),流速为0.6 ml/min;采用电喷雾离子源(ESI),以多重反应监测(MRM)方式扫描,负离子方式检测。用于定量分析的离子分别为m/z 147.10→58.20(米屈肼)和m/z 152.00→110.10(内标,对乙酰氨基酚)。采用DAS 2.1软件分别计算单次、多次给药的药动学参数,并比较其差异。结果:米屈肼血药、尿药浓度分别在0.02~20 ng/ml(r=0.9993)和0.05~40 ng/ml(r=0.9982)范围内线性关系良好,定量限分别为0.02、0.05 ng/ml;精密度、回收率符合生物样品测定要求,内源性杂质不干扰测定。血浆中米屈肼低、中、高剂量(250、500、750 mg)单次给药组t1/2分别为(3.39±0.81)、(5.52±0.57)、(5.32±0.96)h,tmax分别为(0.80±0.45)、(1.38±0.43)、(1.10±0.36)h,cmax分别为(4.17±1.46)、(8.08±1.04)、(15.04±1.86)ng/ml,AUC0-36 h分别为(24.55±5.81)、(45.50±7.07)、(85.60±13.09)ng·h/ml,单次给药在250~750 mg剂量范围内,cmax、AUC0-36 h与剂量呈线性关系(R2分别为0.9745、0.9683);米屈肼低剂量多次给药组达稳态时,cmin为(0.28±0.10)ng/ml,AUCs为(38.78±4.18)ng·h/ml,cs为(1.62±0.17)ng/ml,DF为(3.81±1.14),t1/2为(6.17±1.46)h,tmax为(1.20±0.33)h,cmax为(6.46±1.96)ng/ml,AUC0-36 h为(40.33±4.65)ng·h/ml;cmax、AUC蓄积因子分别为(1.73±0.90)和(1.64±0.40)。多次连续给药达稳态时与单剂量相比,t1/2、cmax、AUC0-36 h均有所改变,tmax无显著性差异。各剂量组单次给药后,26 h尿累积排泄率分别为(0.004009±0.0011)%、(0.004026±0.00101)%、(0.003858±0.00068)%。结论:该试验建立的方法灵敏度好、准确度高、专属性强,适用于人体中米屈肼血药及尿药浓度的测定和药动学研究。米屈肼胶囊在健康人体内具有一定的蓄积作用,且具有线性药动学特征。
