10名男性健康志愿者自身交叉单次口服头孢布烯400mg或肌注头孢呋辛500mg。结果主要动力学参数比较如下:平均Cmax分别为17.93±0.90mg·L-1及18.66±0.74mg·L-1(P>0.05),平均Tmax1.38±0.59及1.05±0.26h(P<0.01),表明肌注头孢呋辛比口服头孢布烯吸收略快,但头孢呋辛消除较快,T1/2仅0.86±0.23h,而头孢布烯T1/2为1.6±0.37h(P<0.001)。另10名男性健康志愿者每日口服头孢布烯400mg,连服3d,第3d的平均Cmax为19.25±0.59mg·L-1,平均Tmax2.35±0.34h,与单剂量比较,两参数在统计学上差异非常显著,然而两组间的T1/2及AUC0→12则无显著性差异
10 male healthy volunteers cross their single oral ceftibuten 400mg or intramuscular cefuroxime 500mg. Results The main kinetic parameters were compared as follows: Mean Cmax were 17.93 ± 0.90 mg · L-1 and 18.66 ± 0.74 mg · L-1, respectively (P> 0.05), with an average Tmax of 1.38 ± 0. 59 and 1.05 ± 0.26h (P <0.01), indicating that intramuscular injection of cefuroxime was slightly faster than oral ceftibuten, but cefuroxime disappeared faster with T1 / 2 of only 0.86 ± 0. 23h while ceftibuten T1 / 2 was 1.6 ± 0.37h (P <0.001). Another 10 male healthy volunteers daily oral ceftibuten 400mg, even serving 3d, the first 3 days of the average Cmax was 19.25 ± 0.59mg · L-1, the average Tmax2.35 ± 0.34h, compared with a single dose , The two parameters were statistically significant differences, however, there was no significant difference between the two groups T1 / 2 and AUC0 → 12
