摘要
正常SD大鼠皮下注射rHuEPO(人基因重组红细胞生成素)的F参数(相对生物利用度)显著高于腹腔注射.单次皮下注射100U/kg时,正常人、尿毒症未透析和腹透组t1/2β(消除相半衰期)分别为15.4±0.9、16.6±6.9和9.2±2.7h.在尿毒症未透析组,皮下注射后血药浓度下降缓慢,F为(41±17)%,用药48h后仍为基础浓度的3倍左右。表明rHuFPO以皮下用药更为合适。
The mean biovailability(F) after s.c. injection of rHuEPO was signincantly higher than that after i.p. injection in healthy SD rats. The mean t1/2β after a s.c.dose of 100U/kg in normal human volunteers, pre-dialysis and peritoneal dialysis uremic patients were 15.4 ± 0.9, 16.6 ± 6.9 and 9.2 ± 2.7 h respectively. In pre-dialysis patients, the mean F after a s.c. dose was 41 ± 17%. Serum rHuEPO concentrations after a s.c. dose decreased slowly and were over three times of baseline 48 hours later. It is concluded that s.c. administration is the optical route for rHuEPO.
