After oral co-administration of two dosages of netobimin (7.5 and 20 mg kg-1 with fenbendazole (1.1 mg kg-1) to Merino sheep, the AUC0-infinity of albendazole sulphoxide at the lower dosage of netobimin, was significantly increased (75.5 per cent) from control value (34.43 +/- 7.91 versus 60.33 +/- 11.93 microg h ml-1). The pharmacokinetic parameters MRT and T1/2 were also increased: 18.96 +/- 2.54 vs 26.44 +/- 4.69 h and 10.31 +/- 1.72 vs 22.28 +/- 6.75 h respectively. No data corresponding to the higher dosage of netobimin (20 mg kg-1) were statistically different from control values. It is concluded that fenbendazole increases the bioavailability of albendazole sulphoxide in sheep at the 7.5 mg kg-1 dosage, and this may produce a potentiated anthelmintic action.
对美利奴羊口服两种剂量的奈托比明(7.5和20毫克/千克)与芬苯达唑(1.1毫克/千克)共同给药后,奈托比明较低剂量时阿苯达唑亚砜的AUC0-无穷大较对照值显著增加(75.5%)(34.43±7.91对60.33±11.93微克·小时/毫升)。药代动力学参数平均滞留时间(MRT)和半衰期(T1/2)也增加:分别为18.96±2.54对26.44±4.69小时以及10.31±1.72对22.28±6.75小时。与奈托比明较高剂量(20毫克/千克)对应的数据与对照值无统计学差异。结论是,芬苯达唑在7.5毫克/千克剂量时可提高绵羊体内阿苯达唑亚砜的生物利用度,这可能产生增强的驱虫作用。
