摘    要:目的建立测定血浆中多潘立酮浓度的HPLC—FL法并研究多潘立酮片的相对生物利用度及其生物等效性。方法按两制剂双周期自身对照交叉试验设计,20名男性健康志愿者分别单剂量口服受试制剂和参比制剂多潘立酮片,用HPLC法测定血药浓度,计算药代动力学参数,并评价两制剂的生物等效性。结果口服多潘立酮片(受试制剂)和多潘立酮片(吗丁啉,参比制剂)20mg后的主要药代动力学参数:受试制剂多潘立酮片t1/2(9.14±0.77)h、Cmax(28.94±4.06)ng·mL^-1、Tmax(0.75±0.24)h、AUC0-1(144.36±30.94)ng·h·mL^-1;参比制剂多潘立酮片t1/2(8.58±1.10)h、Cmax(29.62±5.01)ng·mL^-1、Tmax(0.79±0.32)h、AUC0-1(140.51±31.13)ng·h·mL^-1。以AUC0-1计算,与参比制剂相比受试制剂中多潘立酮的平均相对生物利用度为(103.0±5.4)%。结论两制剂具有生物等效性。

关 键 词:多潘立酮  相对生物利用度  生物等效性  HPLC

Abstract:Aim To determine domperidone concentrations in human plasma and study the pharmacokinetics and relative bioavailability of domperidone tablets. Methods A single dose of 20mg of reference and test domperidone tablets were given to 20 healthy volunteers in a randomized 2-way cross-over study. The plasma concentrations of domperidone were determined by HPLC-FL. The pharmacokinetic parameters as well as relative bioavailability were measured. Results The main pharmacokinetic parameters were t 1/2 ( 9. 14 ± 0.77 ) h, C max ( 28.94 ± 4.06 ) ng·mL^-1 , T max (0.75 ± 0. 24) h, AUC0-1 ( 144.36 ± 30.94) ng·h·mL^-1 for the test drug and t 1/2 ( 8.58 ± 1.10 ) h, Cmax(29. 62 ± 5. 01) ng·mL^-1, Tmax(0.79 ±0.32)h,AUC0-1(140.51 ±31.13)ng·h·mL^-1 for the reference drug. The relative bioavailability of AUC0-30 was (103.0 ± 5.4)%. Conclusion The reference and test domperidone tablets are bioequivalent.
