摘要
目的研究氨金黄敏颗粒试验制剂和参比制剂的人体药动学和相对生物利用度。方法 20名健康男性受试者进行随机双交叉试验,分别单剂量口服4袋氨金黄敏颗粒(每袋含对乙酰氨基酚150 mg,金刚烷胺50 mg,人工牛黄10 mg,氯苯那敏2 mg)参比制剂和试验制剂。采用高效液相色谱(HPLC)法测定人血浆中对乙酰氨基酚的血药浓度,采用液相色谱-串联质谱(LC-MS/MS)法测定人血浆中金刚烷胺和氯苯那敏的血药浓度,用DAS Ver2.0软件计算药动学参数,并进行上述三成分的生物利用度评价。结果参比和试验制剂中对乙酰氨基酚的主要药动学参数ρ_(max)分别为(8 996.7±2 829.0)和(8 720.7±3 393.8)ng·mL^(-1);t_(max)分别为(0.5±0.2)和(0.6±0.4)h;t_(1/2)分别为(2.9±0.8)和(2.9±0.9)h;AUC_(0-t)分别为(31 210.7±10 240.1)和(29 403.4±8 417.7)ng·h·mL^(-1),AUC_(0-∞)分别为(31 396.8±10 311.8)和(29 569.1±8 496.0)ng·h·mL^(-1);金刚烷胺的主要药动学参数ρ_(max)分别为(221.7±32.4)和(226.5±31.0)ng·mL^(-1);t_(max)分别为(2.4±0.7)和(2.0±0.8)h;t_(1/2)分别为(12.8±4.8)和(12.0±4.6)h;AUC_(0-t)分别为(5 094.1±795.5)和(4 897.3±628.7)ng·h·mL^(-1),AUC_(0-∞)分别为(5 616.2±1 235.4)和(5 313.4±996.2)ng·h·mL^(-1);氯苯那敏的主要药动学参数ρ_(max)分别为(4.5±0.8)和(5.4±2.8)ng·mL^(-1);t_(max)分别为(1.7±0.3)和(1.7±0.2)h;t_(1/2)分别为(14.6±4.1)和(15.9±5.3)h;AUC_(0-t)分别为(73.5±11.0)和(77.5±11.6)ng·h·mL^(-1),AUC_(0-∞)分别为(83.0±12.3)和(88.6±16.2)ng·h·mL^(-1);以AUC_(0-t)计算试验制剂中对乙酰氨基酚、金刚烷胺和氯苯那敏对参比制剂的相对生物利用度(F)分别为(95.8±13.2)%、(97.7±16.8)%和(106.5%±15.9)%。结论建立的HPLC以及LC-MS/MS测定法准确、灵敏,结果可靠,统计分析表明氨金黄敏颗粒试验制剂和参比制剂中对乙酰氨基酚、金刚烷胺和氯苯那敏的吸收、分布、消除速率与程度均无明显差异。
AIM To study the pharmacokinetics and bioequivalence of Anjinhuangmin granules test preparation and reference preparation in Chinese healthy volunteers. METHODS Twenty healthy male volunteers were enrolled with a randomized two- way cross-over design. All volunteers received a single oral dosage of 4 bags of test or reference granules (each bag contains paracetamol 150 rag, amantadine 150 rag, artificial cow- bezoar 10 mg and chlorphenamine 2 mg) , respectively. The concentration of paracetamol in plasma was determined by HPLC. The concentrations of amantadine and chlorphenamine in plasma were determined by LC- MS/MS. The pharmacokinetics and bioavailability of two preparations were compared and calculated by DAS Ver2.0 software. RESULTS The main pharmacokinetic parameters for paracetamol reference and test formulations were followed: pmax (8 996.7 ± 2 829.0) and (8 720.7 ± 3 393.8) ng·mL-1, tmax (0.5 ± 0.2) and (0.6 ± 0.4) h; t1/2 (2.9 ± 0.8) and (2.9 ± 0.9) h, AUC0-t (31 210.7 ± 10 240.1) and (29 403.4 ± 8 417.7) ng·h· mL^-1, AUC0-∞ (31 396.8 ± 10 311.8) pharmacokinetic parameters of amantadine and (29 569.1 ± 8 496.0) ng·h ·mL^-1, respectively. The main reference and test formulations were as follows: ρmax (221.7 ± 32.4) and (226.5 ± 31.0) ng·mL^-1, tmax (2.4 ± 0.7) and (2.0 ± 0.8) h, t1/2 (12.8 ± 4.8) and (12.0 ± 4.6) h, AUC0-t (5 094.1 ± 795.5) and (4 897.3± 628.7) ng·h·mL^-1, AUC0-∞ (5 616.2 ±1 235.4) and (5 313.4 ± 996.2) ng·h·mL-1, respectively. The main pharmaeokinetic parameters of chlorphenamine reference and test formulations were as follows: ρmax (4.5± 0.8) and (5.4 ± 2.8) ng·mL-1; tmax, (1.7 ± 0.3) and (1.7 ±0.2) h, t1/2 (14.6 ±4.1) and (15.9 ± 5.3) h, AUC0, (73.5± 11.0) and (77.5 ± 11.6) ng·h·mL^-1, AUC0-∞ (83.0 ± 12.3) and (88.6 ± 16.2) ng·h·mL-1, respectively.
