The pharmacokinetics of ciprofloxacin was investigated in healthy, mature ponies. Ciprofloxacin was administered intravenously to six ponies at a dose of 5 mg per kg body weight. Seven days later, ciprofloxacin was administered orally to each pony at the same dose. Intravenous ciprofloxacin concentration vs. time data best fit a two-compartment open model(More)
The objective of this study was to compare the effectiveness of intramuscular sustained release Pluronic F127 (PF127) gel formulations of deslorelin, a potent GnRH agonist, and GnRH to their solution formulations in inducing the release of luteinizing hormone and formation of luteal tissue in cattle. Injectable gel formulations of deslorelin and GnRH were(More)
The use of high-dose corticosteroids for graft-versus-host disease (GVHD) treatment represents a major risk factor for long-term invasive fungal infections. The aim of this study was to investigate the safety and tolerance of weekly prophylactic administration of once-weekly high-dose (7.5 mg/kg) of liposomal amphotericin B (L-AmB) therapy in 21 adult(More)
OBJECTIVE To evaluate the pharmacokinetic-pharmacodynamic parameters of enrofloxacin and a low dose of amikacin administered via regional IV limb perfusion (RILP) in standing horses. ANIMALS 14 adult horses. PROCEDURES Standing horses (7 horses/group) received either enrofloxacin (1.5 mg/kg) or amikacin (250 mg) via RILP (involving tourniquet(More)
The purpose of this study was to evaluate the pharmacokinetics of ketamine in mature Holstein cows following administration of a single intravenous (i.v.) dose. Plasma and milk concentrations were determined using a high-performance liquid chromatography assay. Pharmacokinetic parameters were estimated using a noncompartmental method. Following i.v.(More)
The objective of this study was to evaluate the efficacy of regional intravenous (i.v.) injection of ceftiofur in delivery of this drug to joint fluid and plasma in a limb distal to a tourniquet in five, healthy, adult, mixed breed beef cattle. A tourniquet was positioned in the mid-metacarpal region, and 500 mg of ceftiofur was administered through a(More)
Phenylbutazone (PBZ) is a nonsteroidal anti-inflammatory drug used in the treatment of chronic pain and arthritis. Topical and transdermal administration of PBZ would be beneficial in large animals in terms of minimizing gastro-intestinal ulcerations and other side effects, easy administration to legs and joints and minimizing the dose to reduce systemic(More)
