吸收、分配和排泄
乙基吡氟菌是容易被吸收并在单次或多次口服5 mg/kg剂量(血浆半衰期为3至3.5小时)后的96小时内排出的。然而,在500 mg/kg的剂量下,吸收达到饱和,表现为Cmax值并未反映出100倍的剂量差异(低剂量组为2.7至2.8 Fg eq/g,高剂量组为100至107 Fg eq-hr/g)。在单次或多次口服低剂量(5 mg/kg)乙基吡氟菌后,尿液排泄占给药放射性活性的27至33%,这表明多次暴露方案并未影响吸收/排泄过程。在单次500 mg/kg剂量后,尿液排泄减少至仅5至7%。通过粪便排泄的放射性活性占所有治疗组剩余的给药放射性活性。在单次5 mg/kg剂量后对胆汁排泄进行分析,发现给药剂量的36%出现在胆汁中。根据排泄数据,低剂量的总生物利用度约为56%。由于缺乏高剂量组的胆汁排泄数据,无法对生物利用度进行确切评估。排泄模式没有表现出性别相关的变异性。然而,女性的血浆和血液清除速度比男性快,这是通过血浆/血液放射性时间过程以及男性较大的AUC值(低剂量组为32.3 vs 18.4 Fg eq-hr/g,高剂量组为2,738 vs 1,401 Fg eq-hr/g)显示出来的。放射性浓度表明,在给药后96小时,任何组织的组织浓度都在或接近检测限(通常小于0.01 Fg eq/g,且从不超过0.02 Fg eq/g)。因此,乙基吡氟菌及其代谢物似乎不会发生显著蓄积。在化合物给药后的组织负担数据并未表明有特定的靶标,除了与口服给药异生物质吸收和消除相关的肝脏和肾脏组织。[美国环保署40 CFR第180部分]
Pyraflufen-ethyl was readily absorbed and excreted within 96 hours following a single or repeated oral dose of 5 mg/kg (plasma t1/2 of 3 to3.5 hours). However, at a dose of 500 mg/kg, absorption was saturated as indicated by Cmax values which did not reflect the 100- fold dose differential (2.7 to 2.8 Fg eq/g for the low-dose group and 100 to 107 Fg eq-hr/g for the high-dose group). Following single or multiple oral low doses (5 mg/kg) of pyraflufen ethyl, urinary excretion accounted for 27 to 33% of the administered radioactivity suggesting that a multiple exposure regimen did not affect the absorption/excretion processes. Urinary excretion was reduced to only 5 to 7% following a single 500 mg/kg dose. Excretion via the feces accounted for the remainder of the administered radioactivity in all treatment groups. Analysis of biliary excretion following a single 5 mg/kg dose showed that 36% of the administered dose appeared in the bile. Based upon the excretion data, total bioavailability of a low dose was approximately 56%. Biliary excretion data were not available for a high-dose group which prevented a definitive assessment of bioavailability. Excretory patterns did not exhibit gender-related variability. However, plasma and blood clearance was more rapid in females than in males as shown by plasma/blood radioactivity time-course and the greater AUC values for males (32.3 vs 18.4 Fg eq-hr/g for the low-dose group and 2,738 vs 1,401 Fg eq-hr/g for the high-dose group). Radioactivity concentrations indicated tissue concentrations at or near detection limits (generally <0.01 Fg eq/g and never exceeding 0.02 Fg eq/g) at 96 hours postdose for any tissues. Therefore, neither pyraflufen-ethyl nor its metabolites appear to undergo significant sequestration. Tissue burden data following compound administration did not suggest a specific target beyond those tissues, namely liver and kidney, which are associated with absorption and elimination of orally administered xenobiotics.[EPA 40 CFR Part 180
