Objective:To explore pharmacokinetics for osthole of YL2000 in normal and febrile rats. Methods:The levels of osthole in plasma were measured through HPLC and the secondary parameters were obtained by fitting the osthole concentration-time data using 3P87 software. Results:In normal and febrile rats
the plasma concentration of osthole was peaked at 1.62h vs.4.02h with a level of 0.03ug/ml vs. 0.04ug/ml
and the t1/2(ke)
t1/2(ka)
CL/F and AUC(0-T) of osthole was 2.98h vs. 2.00h
0.43h vs. 1.09h
4221(mg/kg)/h/(ug/ml) vs.2715(mg/kg)/h/(ug/ml) and 0.189(ug/ml)*h vs. 0.29(ug/ml)*h
respectively. Conclusion:Fever induced effects on pharmacokinetics of osthole
including delay of absorption and increas in AUC(0-T).
