Dosage and Administration: Valbazen Suspension should be administered to cattle and goats at the recommended rate of 4 mL/100 lb of body weight (equivalent to 4.54 mg of albendazole/lb, 10 mg/kg) and to sheep at the recommended rate of 0.75 mL/25 lb of body weight (equivalent to 3.4 mg of albendazole/lb, 7.5 mg/kg). 0000007534 00000 n
Albendazole is a pregnancy class D drug in Australia and pregnancy class C in the United States. Can pregnant cows be dewormed? People have varying gastric pHs on empty stomachs, and thus absorption from one person to another can vary wildly when taken without food.Absorption is also affected by how much of the albendazole is degraded within the small intestine by metabolic enzymes in the villi.The pharmacokinetics of albendazole differ slightly between men and women: women have a lower oral Albendazole undergoes very fast 1st-pass metabolism in all species, such that the unchanged drug is undetectable in plasma.Oxidation to albendazole sulfoxide by FMO produces R(+) Albendazole sulfoxide is converted to the inactive albendazole sulfone by cytochrome P450 oxidases, thought to include CYP3A4There are also some minor hydroxylated sulfated or glucuronidated derivatives.In humans, the metabolites mostly excreted in the bile, with only a small amount being excreted in the urine (less than 1%) and feces.Like all benzimidazoles, albendazole has no residual effect, and thus does not protect well against reinfestations.Albendazole, patented in 1975, was invented by Robert J. Gyurik and Vassilios J. Theodorides and assigned to SmithKline Corporation.In many areas of the world it costs between US$0.01 and US$0.06 per dose.Albendazole is mainly used in cattle and sheep, but has found some use in cats and dogs as well;Albendazole has been used as an anthelminthic and for control of flukes in a variety of animal species, including cattle, sheep, goats, swine, camels, dogs, cats, elephants, poultry, and others.Albendazole has greater bioavailability in ruminants: some albendazole sulfoxide, when released back into the rumen, is reduced to albendazole by the resident microbiota, with a preference of the (+) enantiomer being the substrate.The limitations in early pregnancy are due to a limited period during which teratogenic effects may occur.

Maximum residue limits (MRLs) for albendazole in food, adopted by the FAO/WHO There is a 27 days cattle withdrawal time for meat.Albendazole and related compounds or metabolites like albendazole sulfone (ALB-SO2) exhibit antibacterial effects via an unknown, possibly InChI=1S/C12H15N3O2S/c1-3-6-18-8-4-5-9-10(7-8)14-11(13-9)15-12(16)17-2/h4-5,7H,3,6H2,1-2H3,(H2,13,14,15,16) 0000003499 00000 n
Albendazole, administered orally at a dose rate of 25 mg/kg of body weight to presumed pregnant cows or heifers on days 21, 31, 41, 51, and 61 of gestation, did not induce toxicosis in embryos or fetuses, and all calves born were structurally normal. H�TP=��0��+ Common side effects include nausea, abdominal pains, and headaches.Though albendazole is effective in treating many diseases, it is only FDA-approved for treating hydatid disease caused by dog tapeworm larvae and neurocysticercosis caused by pork tapeworm larvae.In pregnant dogs, albendazole use has led to puppies with reduced weight and with Albendazole sulfoxide is secreted into breast milk at around 1.5% of the maternal dose, though oral absorption is poor enough that it is unlikely to affect nursing infants.The most common side effects by albendazole are, experienced by over 10% of people, Side effects can be different when treating for hydatid disease versus neurocysticercosis; for example, those being treated for the former are more likely to experience elevated liver enzymes and abdominal pain; those being treated for the latter are more likely to experience headache.Because of its low solubility, albendazole often cannot be absorbed in high enough quantities to be toxic.Some parasites have evolved to have some resistance to albendazole by having a different set of acids comprising β-tubulin, decreasing the Oral absorption of albendazole varies among species, with 1–5% of the drug being successfully absorbed in humans, 20–30% in rats, and 50% in cattle.The absorption also largely depends on gastric pH.
