摘  要:目的:研究受试制剂头孢克肟干混悬剂(A)、胶囊剂(B)和参比制剂(C,头孢克肟胶囊,世福素)的人体生物等效性。方法:采用高效液相色谱法测定18名健康受试者三交叉单剂量口服受试制剂或参比制剂200mg后血浆中头孢克肟的浓度。结果:经BIO3程序拟合,A、B、C的AUC0-1分别为(18.54±6.31)、(16.10±5.51)、(17.16±5.96)mg·h-1·L-1,实测Cmax分别为(2.63±0.76)、(2.43±0.78)、(2.57±0.90)mg·L-1,实测tmax分别为(4.11±0.58)、(4.56±0.51)、(4.56±0.70)h,A、B与C的相对生物利用度分别为(108.8±12.3)%和(95.7±15.9)%。结论:受试制剂A与参比制剂C、受试制剂B与参比制剂C具有生物等效性。OBJECTIVE:To study the bioequivalence of suspension formulation of cefixime(A),capsule formulation of cefixime(B) and reference preparation(C: Cefixime Capsules or Cefspan) in human body.METHODS: The study was conducted as a 3 - way crossover design in 18 healthy volunteers whose plasma concentrations of cefixime were determined by HPLC after receiving a single oral dose of 200 mg trial preparations or reference preparation. RESULTS:The main pharmacokinetics of the three preparations(A,B,C) were as follows after undergoing BIO3 program fitting :AUC0-t were( 18.54 ± 6.31)mg·h^-1·L^-1, (16.10±5.51)mg·h^-1·L^-1 and (17.16±5.96)mg·h^-1·L^-1,Cmax were(2.63±0.76)mg·L^-1,(2.43±0.78)mg·L^-1 and (2.57 ± 0.90)mg·L^-1 tmax were(4.11 ± 0.58)h, (4.56 ± 0.51)h and (4.56 ± 0.70) h,respectively .The relative bioavailability of cefixime suspensions(A) and cefixime capsules(B) were (108.8 ± 12.3)% and (95.7 ± 15.9)%, respectively as against reference preparation(C) .CONCLUSION :The test formulations(A and B) were found bioequivalent to the reference formulation(C).
