【摘 要】The pharmacokinetics and residue elimination of mebendazole ( MBZ) were studied in crucian carp Carassius auratus with body weight of ( 50 ± 10) g exposed to oral administration of MBZ at dose of 20 mg/kg bodyweight by a means of high performance liquid

chromatography( HPLC) at water temperature of( 20 ± 0.5) ℃. The drug concentrations in plasma were monitored in the cru-cian carp 0.25 h, 0.5 h, 0.75 h, 1 h, 1.5 h, 2 h, 4 h, 6 h, 8 h, 12 h, 24 h, 36 h, 48 h, and 72 h after drug administration, and analyzed by DAS 3.0 software. The results showed that the concentrations versus time of mebendazole in muscle were well described by two-de-partment open model with first-order absorption after a single oral administration. The residues in the crucian carp by oral administra-tion once a day for 3 d were found to be less than the maximum residue limit( MRL)( 0.0465 μg/mL) at the 25 d for MBZ. The find-ings indicate that the withdrawal time should be no less than 25 d after administration under these conditions.%在水温(20±0.5)℃下,给体质量(50±10)g 的鲫 Carassius auratus 单剂量口灌20mg/k g(体质量)甲苯咪唑后0.25h 0.5h 0.75h 1 h 1.5h 2h 4h 6h 8h 12h 24h 36h 48h ,及72h ,采集鲫血浆,利用高效液相色谱法测定血浆中药物的浓度,


药动学 D A S3.0软件进行数据分析和处理,研究甲苯咪唑在鱼体内的吸收和消除规律。结果表明:单次口灌给药后,甲苯咪唑在血浆中的药时关系符合一级吸收二室开放模型。每天给药一次,连续3d ,氨基甲苯咪唑(MBZ-NH2)于25d 后低于检测限(0.0465μg/mL)。在本试验条件下,建议休药期不低于25d 【总页数】5(P38-42) 【作 者】潘浩;王荻;卢彤岩
