BACKGROUND Veterinary medicines have been widely used for the prevention and treatment of diseases, growth promotion, and to promote feeding efficacy in livestock. As the veterinary medicine industry has steadily grown, it is crucial to set up a baseline for the quality of medicine as well as the insufficiency or excessiveness of the active ingredients in drug products to ensure the compliance,...

Deriving adequate withdrawal intervals for extralabel use of veterinary topical products is difficult because there are limited published data, and data for approved drugs and pesticides are usually proprietary. Where possible, approved products and doses labeled for the specific indication at hand should be used and label withdrawal times should be adhered to. When determining whether topical ...

The rise in incidence of antimicrobial resistance, consumer demands and improved understanding of antimicrobial action has encouraged international agencies to review the use of antimicrobial drugs. More detailed understanding of relationships between the pharmacokinetics (PK) of antimicrobial drugs in target animal species and their action on target pathogens [pharmacodynamics (PD)] has led to...

The use of veterinary drugs in food-producing animals has the potential to generate residues in animal derived products (meat, milk, eggs and honey) and poses a health hazard to the consumer. There are many factors influencing the occurrence of residues in animal products such as drug’s properties and their pharmacokinetic characteristics, physicochemical or biological processes of animals and ...

The prescription data from a digital accounting system of a veterinary teaching hospital collected between 2008 and 2011 in Japan were downloaded, stored in a database and analysed using a statistical analysis software, SAS. Seventy-six per cent of all prescriptions were drugs approved for human beings. The most frequently prescribed category was 'Agents against pathogenic organisms', such as a...

Basic considerations dealing with the biological significance of drug residues and safety evaluation are studied. The specific problem of covalently bound residues is considered from three different points of view. (1) Analytical characteristics clearly distinguish between soluble residues, which deplete relatively fast, and bound material which is slowly eliminated from edible tissues of targe...

The control of veterinary drug residues in milk is performed in Slovenia. The monitoring of antibiotic residues in milk began in 1977. In the last four-ye­ ar period (1995-1998) a total of 3358 samples were analysed and the majority of them (99.4 %) were negative. Antibiotics were found in only 19 samples. De­ termination of sulfonamides in milk was introduced in 1995. In four years we examined...

The aim of this manuscript is to review the potential adverse health effects in humans if exposed to residues of selected veterinary drugs used in food-producing animals. Our other objectives are to briefly inform the reader of why many of these drugs are or were approved for use in livestock production and how drug residues can be mitigated for these drugs. The selected drugs include several a...

background: closantel is a veterinary drug used as anthelmintic for ruminants while it is contraindicated for humans. this report describes a rare case of blindness, increased liver enzymes and coagulopathy following closantel poisoning. case report: a 5-year-old girl was presented with acute blindness following closantel poisoning. she was given mistakenly a dose of 500 mg/day (25mg/kg/day) fo...
