In this study, three hundred and six clinically healthy rainbow trout (110–140 g) were used. The fish received single IV, IP, and PO injections of cefquinome at 10 mg/kg dose. The plasma concentrations of cefquinome were measured using HPLC-UV and were evaluated using non-compartmental analysis. Cefquinome was measured up to 96 h for PO route and 144 h for IV and IP routes in plasma. Following IV administration, t1/2ʎz, ClT, and Vdss were 18.85 h, 0.037 L/h/kg, and 0.84 L/kg, respectively. The Cmax of IP and PO routes was 9.75 and 1.64 μg/ml, respectively. The bioavailability following IP and PO administrations was 59.46% and 12.33%, respectively. Cefquinome at 10 mg/kg dose may maintain T > MIC above 40% at 72 and 96 h intervals, respectively, following the IP and IV routes for bacteria with MIC values of ≤2 μg/ml and at 24 h intervals following the PO route for bacteria with MIC value of ≤0.75 μg/ml. However, further studies are needed to determine in vitro and in vivo antibacterial efficacy and multiple dosage regimens of cefquinome against pathogens isolated from rainbow trout. © 2022 John Wiley & Sons Ltd.John Wiley and Sons Inc2022Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/12638https://doi.org/10.1111/jvp.130910140-7783enJournal of Veterinary Pharmacology and Therapeuticsinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/12638
