摘  要:目的:研究复方布洛芬软胶囊的人体药动学和生物等效性。方法:采用随机交叉试验设计,20名健康男性受试者分别单剂量口服布洛芬软胶囊(布洛芬400 mg,参比制剂)和对乙酰氨基酚片(对乙酰氨基酚500 mg,参比制剂)与复方布洛芬软胶囊(布洛芬400 mg和对乙酰氨基酚325 mg,受试制剂), LC-MS/MS法和HPLC-UV法测定血浆中布洛芬和对乙酰氨基酚的浓度。结果:参比制剂和受试制剂布洛芬的cmax分别为(42±s 9)和(41±10)mg·L-1;tmax分别为(0.6±0.2)和(0.5±0.3)h;t1/2分别为(2.0±0.3)和(2.1±0.3)h;AUC0~12分别为(126±24)和(131±25)mg·h·L-1。对乙酰氨基酚的cmax分别为(7.5±1.2)和(4.6±0.9)mg·L-1;tmax分别为(0.8±0.5)和(0.8±0.4)h;t1/2分别为(2.8±0.6)和(3.0±0.7)h;AUC0~12分别为(27±6)和(17±4)mg·h·L-1。受试制剂布洛芬的相对生物利用度为(105±12)%,经剂量校正后,受试制剂对乙酰氨基酚的相对生物利用度为(96±12)%。结论:受试制剂与参比制剂具有生物等效性。AIM: To study the pharmacokinetics and bioequivalence of compound ibuprofen soft capsules in healthy volunteers. METHODS: Under a randomized crossover trial design, 20 healthy male volunteers were given separately a single oral dose of ibuprofen 400 mg plus acetaminophen 500 mg (reference preparation) and 400 mg/325 mg ibuprofen/acetaminophen (test preparation). Concentrations of ibuprofen and acetaminophen in plasma were determined by methods of LC-MS/MS and HPLC-UV. RESULTS: The main pharmacokinetic parameters for ibuprofen of reference and test preparations were as follows: cmax (42 ± s 9) vs (41 ± 10) mg·L^-1:tmax (0.6±0.2) VS (0.5±0.3) h; t1/2 (2.0±0.3) vs (2.1±0.3) h; AUC0-12 (126±24) VS (131 ±25) mg· h· L^-1, respectively. The main pharmacokinetic parameters for acetaminophen of reference and test preparations were as follows: Cmax (7.5 ± 1.2) vs (4.6 ± 0.9)mg·h·L^-1 tmax (0.8 ± 0.5) vs (0.8 ± 0.4) h; t1/2 (2.8 ± 0.6) vs (3.0 ± 0.7) h; AUC0-12 (27 ± 6) vs (17 ±4) mg·h·L^-1, respectively. The relative bioavailability of ibuprofen was ( 105 ± 12) % and that of acetaminophen was (96 ± 12) % after dosage emendation for test preparation. CONCLUSION: The test and reference preparations possess bioequivalent.
