摘要 目的评价2种布洛芬片在中国健康受试者中的生物等效性,为一致性评价和临床使用提供依据。方法采用单次给药、随机、开放、两周期、双交叉设计,空腹、餐后各42例健康受试者,分别随机分为2组,单次口服布洛芬片受试制剂和参比制剂各0.2 g,用液相色谱-串联质谱法(LC-MS/MS)检测人血浆中布洛芬的浓度,用Phoenix WinNonlin软件(8.0版本),以非房室模型计算药代动力学参数,并评价两种制剂的生物等效性;在试验期间对受试者进行相关的安全性评价。结果单剂量空腹给药后布洛芬主要药代动力学参数如下。受试制剂和参比制剂的Cmax分别为(1.76×10^4±3218.46)和(1.94×10^4±4513.33)ng·mL^-1,AUC0-t分别为(6.69×10^4±1.17×10^4)和(6.45×10^4±1.34×10^4)h·ng·mL^-1,AUC0-∞分别为(6.88×10^4±1.23×10^4)和(6.69×10^4±1.33×10^4) h·ng·mL^-1。受试制剂和参比制剂的Cmax、AUC0-t和AUC0-∞的几何均值比的90%置信区间分别为85.13%~100.62%,100.11%~109.88%和99.64%~107.56%。单剂量餐后给药后布洛芬主要药代动力学参数如下。受试制剂和参比制剂的Cmax分别为(1.61×10^4±4083.11)和(1.62×10^4±4688.51)ng·mL^-1,AUC0-t分别为(5.97×10^4±1.09×10^4)和(6.02×10^4±1.29×10^4)h·ng·mL^-1,AUC0-∞分别为(6.26×10^4±1.33×10^4)和(6.32×10^4±1.48×10^4)h·ng·mL^-1。受试制剂和参比制剂的Cmax、AUC0-t和AUC0-∞的几何均值比的90%置信区间分别为93.08%~109.35%,97.16%~102.40%和96.78%~102.22%,均在80%~125%,判断两种制剂具有生物等效性。此外,在试验期间所有受试者所发生的不良事件均为轻度呈一过性,未发生严重不良事件。结论布洛芬片受试制剂和参比制剂具有生物等效性,安全性良好。 Objective To evaluate the bioequivalence of two kinds of ibuprofen tablets in healthy Chinese subjects after single oral administration to provide a basis for consistency evaluation and clinical use. Methods Using a single-dose, randomized, open-lable, two-period, two-way crossover design, 42 healthy subjects for fasting study and 42 healthy subjects for fed study were enrolled, respectively, and randomized into two groups to receive a single dose of test(T) 0.2 g or reference(R) 0.2 g with 7-day washout period. Plasma concentration of ibuprofen was determined by liquid chromatography-tandem mass spectrometry(LC-MS/MS) method. The pharmacokinetic parameters were calculated by Win Nonlin software(8. 0 version) using non-compartmental model, and bioequivalence evaluation was performed for the two preparations. Relevant safety evaluations were performed during the trial. Results The main pharmacokinetic parameters of ibuprofen after a single oral dose of ibuprofen tablet under fasting condition for T and R were as follows: Cmaxwere(1. 76 ×10^4± 3218. 46) and(1. 94 ×10^4± 4513. 33)ng·mL^-1;AUC0-twere(6. 69 ×10^4± 1. 17 ×10^4) and(6. 45 ×10^4± 1. 34 ×10^4) h·ng·mL^-1,and AUC0-∞ were(6. 88 ×10^4± 1. 23 ×10^4) and(6. 69 ×10^4± 1. 33 ×10^4) h·ng·mL^-1,respectively. The 90% CIs for the geometric mean ratios(GMR) of Cmax,AUC0-t and AUC0-∞ of T and R under fasting condition were 85. 13%-100. 62%,100. 11%-109. 88% and 99. 64%-107. 56%,respectively. The main pharmacokinetic parameters of Ibuprofen under fed condition for T and R were as follows: C4 maxwere(1. 61 × 10± 4083. 11) and(1. 62 ×10^4±4688. 51) ng·mL^-1,AUC0-t were(5. 97 ×10^4± 1. 09 ×10^4) and(6. 02 ×10^4± 1. 29 ×10^4) h·ng·mL^-1,and AUC0-∞were(6. 26 ×10^4± 1. 33 ×10^4) and(6. 32 ×10^4± 1. 48 ×10^4) h·ng·mL^-1. The 90% CIs for GMR of Cmax,AUC0-t and AUC0-∞of T and R under fed condition were 93. 08%-109. 35%,97. 16%-102. 40% and 96. 78%-102. 22%,respectively. The results demonstrated the bioequivalence of the ibuprofen tablets between T and R. All adverse events occurred were mild and transient,and no serious adverse event was reported. Conclusion The test formulation and reference formulation of ibuprofen tablets were equivalent and safe.
