OBJECTIVE To determine the pharmacokinetics and pharmacodynamics of danofloxacin in goats and the concentrations required to induce bacteriostasis, bactericidal activity, and bacterial elimination. ANIMALS 6 healthy British Saanen goats. PROCEDURE Danofloxacin (1.25 mg/kg of body weight) was administered i.v. and i.m. in a cross-over design with 14 days(More)
The fluoroquinolone antimicrobial drug danofloxacin was administered to sheep intravenously (i.v.) and intramuscularly (i.m.) at a dose of 1.25 mg/kg of body weight in a two-period crossover study. The pharmacokinetic properties of danofloxacin in serum, inflamed tissue cage fluid (exudate), and noninflamed tissue cage fluid (transudate) were established by(More)
Platelet-activating factor (PAF) causes oedema and neutrophil accumulation when injected into the skin of normal horses. PAF is also known to induce aggregation of horse platelets in vitro. The selective PAF receptor antagonist WEB 2086 has now been used to determine whether these effects are mediated by PAF receptor activation. Addition of WEB 2086 to(More)
1 Data on the relationships between plasma concentration and analgesic and anti-inflammatory effects of NSAIDs are limited because most inflammation models do not permit pharmacokinetic/pharmacodynamic (PK/PD) modelling to be readily performed. 2 In this study, a kaolin-induced inflammation model in the cat was evaluated for pre-clinical characterization of(More)
The pharmacokinetics and pharmacodynamics of danofloxacin were studied in the camel in a two period cross-over study. After intravenous (i.v.) administration at a dose rate of 1.25 mg/kg, the pharmacokinetics of danofloxacin indicated a high volume of distribution (V(d(area))=3.43 L/kg), relatively rapid clearance (0.44 L/kg/h) and half-life of 5.37 h.(More)
The pharmacokinetics and pharmacodynamics of danofloxacin were studied in calves after intravenous (IV) and intramuscular (IM) administration, at a dose of 1.25 mg/kg in a two period cross-over study, using tissue cages to monitor aspects of extravascular distribution. Danofloxacin had a high volume of distribution (3.90 L/kg) and relatively rapid clearance(More)
The antimicrobial properties of amoxicillin were determined for the bovine respiratory tract pathogens, Mannheima haemolytica and Pasteurella multocida. Minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and time-kill curves were established. Pharmacokinetic (PK)/pharmacodynamic (PD) modelling of the time-kill data, based on(More)
Nitric oxide (NO) has been implicated in the inhibition of cell proliferation in cytokine and lipopolysaccharide (LPS)-stimulated chondrocytes and is known to be influenced by physical forces in several tissues. In this study, a well-characterized model system utilizing bovine chondrocytes embedded in 3% agarose constructs has been used to investigate the(More)
The development of reproducible models of acute inflammation in which inflammatory heat is easily quantified and from which inflammatory exudate is readily harvested has facilitated studies in the horse of the actions of steroids and non-steroidal anti-inflammatory drugs (NSAIDS). Blockade of the synthesis of eicosanoids and suppression of inflammatory heat(More)
