Pharmacokinetics of cefquinome in goats after intramuscular administration alone and with meloxicam. International Journal of Basic & Clinical Pharmacology. 2020 Apr; 9(4): 518-5222319-20032279-0780http://imsear.searo.who.int/handle/123456789/200570Background: Nonsteroidal anti-inflammatory drugs and antibiotics are commonly prescribed together. We aimed to study the kinetic profile of cefquinome (2 mg/kg b.wt.) following intramuscular administration of it alone and co-administered with meloxicam (0.2 mg/kg b.wt.) in goats.Methods: Five Egyptian Baladi goats, each goat was injected intramuscularly at the dose rate of 2 mg/kg b.wt. Cefquinome into the deep gluteal muscle of hindquarter alone and then after fifteen days washout period, these animals also injected intramuscularly at the dose rate of 2 mg/kg b.wt. Cefquinome preceded with meloxicam at the dose rate of 0.2 mg/kg b.wt. The serum concentrations of cefquinome were detected by high performance liquid chromatography, two compartment model.Results: Following a single dose intramuscular administration of cefquinome alone, peak plasma concentration (1.71�0189 ?g/ml) was obtained at 1.59�0038 h. The absorption half-life (t1/2ab), total body clearance (Cltot), elimination half-life (t1/2el) and area under curve (area under concentration (AUC(0-inf)) of cefquinome were 0.4�0028 h, 0.068�78 l/h/kg, 9.21�178h and 29.36�78 礸.h.ml-1, respectively. Following a single dose intramuscular co-administration of cefquinome and meloxicam, peak plasma concentration (1.60�0124 ?g/ml) was obtained at 1.49�0092 h. The absorption half-life (t1/2ab), total body clearance (Cltot), elimination half-life (t1/2el) and area under curve (AUC(0-inf)) of cefquinome were 0.396�006 h, 0.094�25 l/h/kg, 6.5�221 h and 21.38�696 礸/h/ml, respectively. Non significant alters were reported in the parameters following co-administration of Cefquinome with meloxicam.Conclusions: From our results, may be concluded that intramuscular administration of meloxicam may be successfully co-administrated with cefquinome for combating bacterial infections with an inflammatory condition in goats without any antagonistic effect.KineticCefquinomeMeloxicamIntramuscularGoatsJournal ArticleIndiaDepartment of Pharmacology, Faculty of Veterinary Medicine, University of Sadat City, EgyptDepartment of Pharmacology, Faculty of Veterinary Medicine, Menoufia University, Egypt
