Antibiotics (Basel) 2022; 11:antibiotics11060741. [PMID: 35740148 PMCID: PMC9219738 DOI: 10.3390/antibiotics11060741] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Revised: 05/21/2022] [Accepted: 05/26/2022] [Indexed: 02/04/2023] Open
Abstract
In avian medicine, the use of antibiotic dosing regimens based on species-specific pharmacological studies is ideal. However, due to a lack of such studies, dose extrapolation, which may cause inefficacy and toxicity, is common practice. Multiple searches were performed using the PubMed and Web of Science databases to extract relevant pharmacological studies performed in exotic avian species. The pharmacokinetics (PK), pharmacodynamics (PD), and safety data of the selected antibiotics (enrofloxacin, marbofloxacin, gentamicin, amikacin, ceftiofur, doxycycline, and amoxicillin/clavulanate) from these studies were reviewed. This review aimed to identify trends amenable for safe inter-species dose extrapolation and provide updated findings on dosing regimens that are safe and efficacious for various exotic avian species. We observed that the half-life of antibiotics appears to be shorter in the common ostrich and that amikacin may be amenable to inter-species dose extrapolation as it is safe and shows little inter-species PK and PD variation. Species-specific enrofloxacin dosing regimens that were not listed in the Exotic Animal Formulary (5th ed.) were found for Caribbean flamingos, African penguins, southern crested caracaras, common ostriches, and greater rheas. Specific dosing regimens recommended for psittacine birds (doxycycline 130 mg/kg medicated water) and ratites (PO doxycycline 2–3.5 mg/kg q12 h, PO enrofloxacin 1.5–2.5 mg/kg q12 h and IM enrofloxacin 5 mg/kg q12 h) in the formulary may not be effective in budgerigars and common ostriches, respectively. Apart from the lack of species-specific pharmacological studies, a lack of multiple dose studies was also noted.

Waxman S, de Lucas JJ, Wiemeyer G, Torres Bianchini L, San Andrés MI, Rodríguez C. Pharmacokinetic Behaviour of Enrofloxacin after Single Intramuscular Dosage in American Black Vultures ( Coragyps atratus). Antibiotics (Basel) 2021; 10:antibiotics10080957. [PMID: 34439007 PMCID: PMC8389010 DOI: 10.3390/antibiotics10080957] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Revised: 08/02/2021] [Accepted: 08/06/2021] [Indexed: 11/17/2022] Open
Abstract
The aim of the study was to investigate the intramuscular pharmacokinetics of enrofloxacin in black vultures (Coragyps atratus). The pharmacokinetics of a single intramuscular dose (10 mg/kg) of enrofloxacin was studied in six vultures. Plasma concentrations of enrofloxacin and its active metabolite, ciprofloxacin, were determined by high-performance liquid chromatography (HPLCuv). Pharmacokinetic parameters were estimated using non-compartmental and compartmental analysis. After intramuscular administration, enrofloxacin showed a rapid and complete absorption, reaching a Cmax value of 3.26 ± 0.23 μg/mL at 1.75 ± 0.53 h. A long terminal half-life of 19.58 h has been observed. Using previously published MIC values to perform a PK/PD analysis, cumulative fraction responses obtained after Monte Carlo simulation for AUC/MIC > 30, 50 and 125 were 72.93%, 72.34% and 30.86% for E. coli and 89.29%, 88.89% and 58.57% for Mycoplasma synoviae, respectively. Cumulative fraction responses obtained for Cmax/MIC index were 33.93% and 40.18% for E. coli and M. synoviae, respectively. The intramuscular administration of 10 mg/kg could be appropriate to treat infectious diseases caused by gram-positive bacteria with MIC value lower than 1 µg/mL; however, although enrofloxacin showed a slow elimination in black vultures, plasma concentrations were insufficient to reach the gram-negative stablished breakpoints.

EVALUATION OF LOCALIZED INFLAMMATORY REACTIONS SECONDARY TO INTRAMUSCULAR INJECTIONS OF ENROFLOXACIN IN STRIPED BASS ( MORONE SAXATILIS). J Zoo Wildl Med 2020; 51:46-52. [PMID: 32212545 DOI: 10.1638/2019-0096] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 10/15/2019] [Indexed: 11/21/2022] Open
Abstract
Enrofloxacin is a fluoroquinolone widely used in animals including fish. Intramuscular (IM) injection of enrofloxacin is a feasible and efficacious option for drug delivery. In many species IM injection has been associated with injection site reactions and increases in serum muscle enzymes. Injection site reactions have not been well characterized in fish. Three groups of striped bass (Morone saxatilis) received an IM injection of enrofloxacin 2.27% in the right epaxial musculature 24, 48, or 96 hr prior to evaluation. Mean dose was 7.69 mg/ kg (6.14-9.69 mg/kg). The 24- and 48-hr groups received an injection of equal-volume 0.9% saline in the left epaxial musculature. A corresponding noninjected tissue sample was designated in the left epaxial musculature from each fish of the 96-hr group. Fish were euthanized and injection sites and noninjection control sites were evaluated grossly and histologically. Grades 1-4 were assigned to samples, with grade 1 corresponding to normal tissue and grades 2, 3, and 4 corresponding to mild, moderate, and severe inflammation and/or necrosis respectively. Externally, all control and injection sites appeared visually unremarkable. On cut surface, epaxial muscle of the enrofloxacin-injected tissue appeared moderately to severely hemorrhagic compared to saline and noninjected tissue, which was normal or mildly hemorrhagic. Histologically, eight of eight noninjected tissues were grade 1. For saline-injected tissues, 14 of 16 tissues were grade 2 and 2 samples were grade 3 when 24- and 48-hr groups were combined. For enrofloxacin-injected tissues, 8 of the 8 24-hr samples were grade 3 and 16 of the 16 48- and 96-hr samples were grade 4. These data show that IM injection of enrofloxacin 2.27% is associated with severe hemorrhage, necrosis, and inflammation in striped bass, and may negatively affect animal welfare.

Abstract
Enrofloxacin is a fluoroquinolone antimicrobial that is widely used in veterinary medicine because of its bactericidal activity and safety in a broad range of species. Caribbean flamingos, a member of the order Phoenicopteriformes, are popular in zoological collections and suffer from a variety of conditions that can result from or lead to bacterial infection. In this study, two groups of 7 adult captive Caribbean flamingos received a single dose of 15 mg/kg enrofloxacin, administered either orally or subcutaneously. Plasma concentrations of enrofloxacin and its metabolite, ciprofloxacin, were measured using liquid chromatography and mass spectrometry. Pharmacokinetic analysis was performed using noncompartmental methods. The pharmacokinetic parameters for both routes of administration were similar, with a mean peak plasma concentration (Cmax) of 5.25 and 5.77 μg/ml, a mean time to peak plasma concentration (Tmax) of 1.49 and 1.1 hr, a mean area under the curve (AUC) of 49.9 and 47.3 hr·μg/ml, and a mean terminal half-life (t1/2) of 5.83 and 6.46 hr for oral and subcutaneous dosing, respectively. Conversion to ciprofloxacin was minimal, with the AUC of ciprofloxacin representing <3% of the enrofloxacin AUC for both routes of administration. Based on the results of the present study, a dose of 15 mg/kg enrofloxacin delivered either orally or subcutaneously in the Caribbean flamingo every 24 hr is recommended for susceptible bacterial pathogens with a minimal inhibitory concentration ≤ 0.25 μg/ml.

Abstract
Given the limited information available in this species, the aim of this study was to investigate the pharmacokinetic characteristics of enrofloxacin (ER) and its major metabolite ciprofloxacin (CP) in buffaloes, Bubalus bubalis. ER was administered intravenously (i.v.) or subcutaneously (s.c.) to buffaloes at doses of 5.0 and 7.5 mg/kg BW, and plasma, urine and fecal samples were collected until 48 hr post-administration. The concentrations of ER and CP in the plasma, urine and feces were analyzed using high-performance liquid chromatography equipped with a fluorescence detector. The plasma concentrations of ER and CP could be determined up to 24 hr and 32 hr after i.v. and s.c. administrations at doses of 5.0 and 7.5 mg/kg BW, respectively. CP concentrations were always lower than those of parental drug. The s.c. bioavailability of ER was 52.36 ± 4.24% and 72.12 ± 5.39% at doses of 5.0 and 7.5 mg/kg BW, respectively. Both ER and CP were detectable in urine and feces up to 24 hr. ER and CP were mainly excreted via the urine. Based on the pharmacokinetic data and PK-PD indices, s.c. administration of ER at doses of 5.0 and 7.5 mg/kg BW might be appropriate for the treatment of susceptible bacterial diseases in Thai swamp buffaloes.
