Oxfendazole was tested against Raillietina tetragona in experimentally infected chickens using single oral doses of 20, 10, 7.5, 5, and 2.5 mg/kg body weight. The minimal dose of the drug which produced 100% efficacy against immature worms was 10 mg/kg whereas the same effect on the mature parasite was obtained with 7.5 mg/kg. Doses lower than these significantly reduce worm burdens. The compound appears to be safe for chickens and a dose of 20 mg/kg (twice the recommended dose) produced no untoward clinical reactions. 相似文献

OBJECTIVE: To determine pharmacokinetics and metabolic patterns of fenbendazole after IV and oral administration to pigs. ANIMALS: 4 mixed-breed female pigs weighing 32 to 45 kg. PROCEDURE: Fenbendazole was administered IV at a dose of 1 mg/kg. One week later, it was administered orally at a dose of 5 mg/kg. Blood samples were collected for up to 72 hours after administration, and plasma concentrations of fenbendazole, oxfendazole, and fenbendazole sulfone were determined by use of high-pressure liquid chromatography. Plasma pharmacokinetics were determined by use of noncompartmental methods. RESULTS: Body clearance of fenbendazole after IV administration was 1.36 L/h/kg, volume of distribution at steady state was 3.35 L/kg, and mean residence time was 2.63 hours. After oral administration, peak plasma concentration of fenbendazole was 0.07 microg/ml, time to peak plasma concentration was 3.75 hours, and mean residence time was 15.15 hours. Bioavailability of fenbendazole was 27.1%. Oxfendazole was the major plasma metabolite, accounting for two-thirds of the total area under the plasma concentration versus time curve after IV and oral administration. Fenbendazole accounted for 8.4% of the total AUC after IV administration and 4.5% after oral administration. CONCLUSIONS AND CLINICAL RELEVANCE: Results indicate that fenbendazole was rapidly eliminated from plasma of pigs. The drug was rapidly absorbed after oral administration, but systemic bioavailability was low. 相似文献

Monensin toxicosis in swine: potentiation by tiamulin administration and ameliorative effect of treatment with selenium and/or vitamin E 总被引：2，自引：0，他引：2
J F Van Vleet L J Runnels J R Cook A B Scheidt 《American journal of veterinary research》1987,48(10):1520-1524
Modulation of acute monensin toxicosis in swine was evaluated in 2 studies. In study 1, 56 weanling male pigs were allotted to 14 groups of 4 each. Pigs in 7 groups were given tiamulin in the drinking water (to supply 7.7 mg/kg of body weight/day) for 3 days before and for 2 days after monensin administration. Monensin was given as a single oral dose (at 0, 7.5, 15, 25, 50, 75, or 100 mg/kg) to pigs in groups with or without tiamulin exposure. Prominent acute clinical signs of monensin toxicosis (hypermetria, hind limb ataxia, paresis, knuckling of hind limbs, and recumbency) developed by 2 to 6 hours after dosing in pigs given 15 or 25 mg of monensin/kg with tiamulin exposure, but not in pigs given the 15 or 25 mg of monensin/kg without tiamulin exposure. Also, the extent of monensin-induced skeletal muscle damage at 4 days after monensin dosing was enhanced in pigs given 7.5, 15, or 25 mg of monensin/kg and exposed to tiamulin. In study 2, 48 weanling male pigs were allotted to 8 groups of 6 each. Four groups of pigs were given 20 mg of monensin/kg orally, and 4 groups were given 100 mg of monensin/kg orally. For each monensin dose, a group was treated 24 hours before monensin administration with (i) selenium (Se)-vitamin E preparation, 0.25 mg of Se and 68 IU of d-alpha-tocopheryl acetate (vitamin E)/kg, IM; (ii) vitamin E only, 68 IU of d-alpha-tocopheryl acetate/kg; (iii) Se only, 0.25 mg of Se/kg; or (iv) vehicle.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

The efficacy of clorsulon and of albendazole against Fascioloides magna were evaluated in 36 naturally infected white-tailed deer (Odocoileus virginianus) in southern Texas. A single oral dose of clorsulon suspension (12 to 30 mg/kg of body weight; mean = 24 mg/kg) was given to each deer and killed 153 (92%) of 167 mature flukes and 4 (80%) of 5 immature flukes recovered at necropsy. A single oral dose of albendazole paste (17 to 46 mg/kg; mean = 26 mg/kg) was given to each deer and killed 148 (89%) of 167 mature flukes and 4 (67%) of 6 immature flukes recovered at necropsy. In 82 nontreated control deer, 271 live flukes were recovered; dead flukes were not recovered. 相似文献

The pharmacokinetics of amoxicillin (Amx) were determined in pigs following intravenous (IV) administration of a single dose of 15 mg/kg and a single dose of 15 mg/kg of a new oral formulation (Amx-FP containing 10% amoxicillin). Residue studies were performed to determine residues in edible tissues of healthy pigs after chronic oral administration of Amx-FP at a daily dose of 15 mg/kg for five consecutive days. After IV administration, the plasma concentration was characteristic of a two-compartment open model. The main pharmacokinetic variables were: t(1/2lambda(n)), MRT=90.1 min, V(darea)=0.81 L/kg and Cl(b)=3.9 mL/kg/min. After single oral administration the main pharmacokinetic variables were: C(max)=758 mug/L, t(max)=347 min and Cl(b/f)=3.7 mL/kg/min for Amx-FP. The oral bioavailability (F) was calculated at 11% for Amx-FP. Based on maximum residue levels (MRL) for AMX in pigs established at 50 microg/kg for all tissues, the withdrawal times of AMX in muscle and skin plus fat were estimated (95% tolerance limit and 95% confidence) to fall below the MRL after a withdrawal period of seven days. Levels of AMX in the liver and kidneys were estimated to fall below the MRL after a withdrawal period of four days. 相似文献

为了探讨氟苯尼考双混悬型乳剂的临床治疗效果,确定用药方案,本试验建立体重为15kg±1.5kg的杜×长×大三元杂交商品猪胸膜肺炎人工感染病理模型。以氟苯尼考注射液为对照组,采用氟苯尼考双混悬型乳剂高(40mg/kg)、中(20mg/kg)和低(10mg/kg)剂量组进行临床治疗与观察。结果表明,氟苯尼考双混悬型乳剂高、中试验组治愈率均为100%,显著高于低剂量组和药物对照组(P<0.05)。因此,临床治疗推荐采用中(20mg/kg)剂量组,3d1次,连用2次的给药方案。 相似文献

Oxfendazole was administered to pregnant cows at 2.5 and 5 mg/kg body weight to determine the anthelmintic efficacy against naturally acquired larvae which became inhibited at the early 4th stage. The experimental design included three groups of orally-treated cows, that is, 10 placebo treated control cows, 11 cows treated with 2.5 mg/kg of oxfendazole and 10 cows treated with 5.0 mg/kg of oxfendazole. Oxfendazole at 2.5 mg/kg body weight was 82 and 94% effective against EL-4 and adult O. ostertagi, respectively. At 5 mg/kg, Oxfendazole was 95 and 99% effective against EL-4 And adult O. ostertagi, respectively. The results suggested the use of a field dosage level of 5 mg/kg body weight oxfendazole where inhibited larvae may be encountered. 相似文献
