摘要
目的:建立吡罗昔康血药浓度的高效液相色谱(HPLC)测定法,进行人体药动学研究。方法:采用HPLC法,测定16名健康受试者口服安吡昔康后血浆中吡罗昔康浓度。结果:口服受试制剂(单剂量含安吡昔康13.5 mg,27 mg,多剂量13.5 mg,qd×10 d)后,估算的吡罗昔康的药动学参数t_(1/2)β分别为(59±s5),(59±9),(59±6)h;t_(max)分别为(4.8±1.5),(4.3±1.3),(4.4±0.7)h;c_(max)分别为(1.20±0.20),(2.4±0.3),(5.0±0.6)mg·L^(-1);V1/F分别为(10±3),(10±4),(11±3)L;V/F分别为(12±3),(12±3),(13±3)L;AUC_(0-(?))分别为(93±11),(223±40),(122±23)mg·h·L^(-1);MRT_(?)为(65±6),(68±8),(69±9)h。结论:本方法结果准确,灵敏度高,吡罗昔康在大部分人体内的过程符合二室开放模型,其主要药动学参数与国内外文献报道数据一致。
AIM: A method was estabilished to study the pharmacokinetics of ampiroxicam tablet in 16 Chinese heathhy volunteers through HPLC test of piroxicam concentration in plasma. METHODS : Sixteen healthy volunteers received ampiroxicam tablet (a single oral dose of ampiroxicam 13.5, 27 mg and multidose 13.5 mg, qd × 10 d). Piroxicam concentrations in plasma were determined by HPLC. RESULTS: The main pharmacokinetic parameters of piroxicam were as followings: t 1/2 β: (59 ± s 5) ; (59 ± 9) and (5 ± 6) h; tmax: (4.8 ± 1.5), (4.3 ± 1.3) and (4.4± 0.7) h; Cmax,: (1.20 ± 0.20), (2.4 ± 0.3) and (5.0 ± 0.6) mg ·L^-1; V1/F: (10 ± 3), (10 ± 4) and (11 ± 3) L; V/F:(12 ± 3), (12 ± 3) and (13 ± 3) L; AUC0-4:(93 ± 11), (223 ± 40) and (122 ± 23) mg·h· L^-l; MR T0-t: (65 ±6), (68 ± 8) and (69 ± 9) h. CONCLUSION: HPLC test method to piroxieam is accurate, sensitive and reliable, coinciding to the process taken in a two-compartment open pharmaeokinetie model and revealing the equality with other reported by domestic and imported articles.
