Abstract
The Pharmacokinetic/Pharmacodynamic (PK/PD) relationship of antimicrobial drugs (AMD) for surgical prophylaxis has been poorly studied, hampering evidence-based decision making around AMD dosing and timing. Our objective is to use PK/PD principles to inform (1) the timing of administration and (2) the interval for re-administration of AMD used peri-operatively in dogs. Raw plasma concentrations of cefazolin, cefuroxime, cefalexin, amoxicillin and ampicillin were retrieved from original intravenous studies performed in dogs. E. coli and methicillin-susceptible staphylococci were identified as possible intraoperative contaminants and their epidemiological cut-offs (ECOFF) were retrieved from the EUCAST database. Individual PK data were refitted with non-linear mixed effect models (Phoenix®). We performed Monte Carlo simulation to compute i) the 95th percentile of time of peak concentration in the peripheral compartment (informing timing between administration and first incision) and ii) the duration for which at least 90% of dogs maintain a free plasma concentration above ECOFF (informing timing of re-administration: 1.5 to 4h). Cefazolin (22-25mg/kg), cefuroxime (20mg/kg), cefalexin (15mg/kg) and amoxicillin (16.7mg/kg) reached peak peripheral concentrations within 30min, but ampicillin (20mg/kg) required 82min, respectively. For methicillin-susceptible staphylococci, cefazolin and cefuroxime require re-administration every 2h, whereas cefalexin and both amoxicillin and ampicillin can be readministered every 3 and 4h, respectively. For E. coli, only cefazolin provided adequate perioperative coverage with 2-hourly administration, where cefuroxime and cefalexin failed uniformly. Alternatively, ampicillin and amoxicillin (critically ill dogs) may cover E. coli contaminations, but only if readministered every 1.5h. These PK-derived conclusions provide a rationale for perioperative AMD administration timing.

Abstract
Azithromycin is a macrolide antimicrobial agent of the azalide group with a broad spectrum of activity against gram-negative and gram-positive bacterial organisms. Tolfenamic acid is a non-steroidal anti-inflammatory drug of the fenamate group, which is used extensively in humans and animals due to its anti-inflammatory, analgesic, and antipyretic properties. There is dearth of literature on any type of drug interaction between azithromycin and tolfenamic acid in any species, including human beings and alteration of its pharmacokinetics by fever. Therefore, the objective of this study was to investigate the alteration of disposition kinetics of azithromycin alone and in the presence of tolfenamic acid in Malabari goats by fever, following an intravenous administration at a dose rate of 20 mg/kg body weight. Blood samples collected from both afebrile and febrile goats at predetermined time intervals after the administration of azithromycin alone and then in combination with tolfenamic acid (2 mg/kg, intravenously), respectively, were analyzed using high-performance liquid chromatography. Non-compartmental analysis was used to determine the peak blood concentration (C max), time-to-peak plasma concentration (T max), half-life (t 1/2λz ), area under the curve (AUC 0-t, AUC 0-inf), area under the first moment curve (AUMC 0-inf), mean residence time (MRT0-inf), apparent volume of distribution at steady state (V ss), and the total body clearance of drug from the blood (Cl). In febrile animals, significant differences were noted in the values of C max, Cl, and V ss. Thus, azithromycin disappears into an additional compartment in febrile goats, which may be due to its extended cellular penetration into the inflammatory cells, resulting in anti-inflammatory activity. Tolfenamic acid significantly altered the pharmacokinetics of azithromycin in both normal and febrile animals. Tolfenamic acid, being a better anti-inflammatory agent, suppresses the inflammatory mediators, reducing the possibility of increased utilization of azithromycin in febrile condition.

Abstract
Pharmacokinetics of cefquinome was studied in febrile female goats following its intravenous (IV) administration at the dose rate of 2 mg/kg body weight. The fever was induced by administration of Escherichia coli lipopolysaccharide (lμg/kg body weight). Cefquinome concentration in plasma of goats was estimated using HPLC. The drug was detected upto 24 h in febrile goats. The disposition kinetics of the drug was described by twocompartment open model. PK-PD indices; AUC24h/MIC, Cmax/MIC, T>MIC were calculated by integrating in-vivo PK data with earlier generated MIC data against Pasteurella (P.) multocida. A favourable PK and PK-PD indices suggested that the dose of 2 mg/kg/24 h of cefquinome would be effective clinically to treat goats affected with P. multocida infections.

Abstract
AIM To compare the pharmacokinetic parameters of cefuroxime lysine, a new second-generation of cephalosporin antibiotics, after intravenous (IV), intraperitoneal (IP), or intramuscular (IM) administration. METHODS Twelve male and 12 virgin female Sprague-Dawley rats, weighing from 200 to 250 g, were divided into three groups (n=4 for each gender in each group). The rats were administered a single dose (67.5 mg/kg) of cefuroxime lysine via IV bolus or IP or IM injection. Blood samples were collected and analyzed with a validated UFLC-MS/MS method. The concentration-time data were then calculated by compartmental and non-compartmental pharmacokinetic methods using DAS software. RESULTS After IV, IP or IM administration, the plasma cefuroxime lysine disposition was best described by a tri-compartmental, bi-compartmental or mono-compartmental open model, respectively, with first-order elimination. The plasma concentration profiles were similar through the 3 administration routes. The distribution process was rapid after IV administration [t(1/2(d)), 0.10 ± 0.11 h vs 1.36 ± 0.65 and 1.25 ± 1.01 h]. The AUMC(0-∞) is markedly larger, and mean residence time (MRT) is greatly longer after IP administration than that in IV, or IM routes (AUMC(0-∞): 55.33 ± 20.34 vs 16.84 ± 4.85 and 36.17 ± 13.24 mg·h(2)/L; MRT: 0.93 ± 0.10 h vs 0.37 ± 0.07 h and 0.65 ± 0.05 h). The C(max) after IM injection was significantly higher than that in IP injection (73.51 ± 12.46 vs 49.09 ± 7.06 mg/L). The AUC(0-∞) in male rats were significantly higher than that in female rats after IM administration (66.38 ± 16.5 vs 44.23 ± 6.37 mg·h/L). There was no significantly sex-related difference in other pharmacokinetic parameters of cefuroxime lysine between male and female rats. CONCLUSION Cefuroxime lysine shows quick absorption after IV injection, a long retension after IP injection, and a high C(max) after IM injection. After IM administration the AUC(0-∞) in male rats was significantly larger than that in female rats.

Abstract
To investigate the bioequivalence and the population pharmacokinetics of cefuroxime lysine and cefuroxime sodium in healthy beagle dogs. A randomized 2-period crossover design in 18 healthy beagle dogs after receiving 20, 40, and 80 mg/kg of cefuroxime lysine or cefuroxime sodium was conducted. A 3-compartment open model was used as the basic model for the population pharmacokinetic study. Both of the antibiotics exhibited dose-proportional pharmacokinetics over the dose range of 20-80 mg/kg. The mean relative bioavailability of cefuroxime lysine versus cefuroxime sodium was 1.05 (range, 0.71 to 1.42), with a significant difference between males and females. The estimates of population pharmacokinetic of CL, V(1), Q(2), V(2), Q(3), V(3) were 3.74 mL/h, 1.70 mL, 29.5 mL/min, 3.58 mL, 0.31 mL/min, and 158 mL for cefuroxime lysine and 4.10 mL/h, 1.00 mL, 38.5 mL/min, 4.19 mL, 0.06 mL/min, and 13.6 mL for cefuroxime sodium, respectively. The inter-individual variability was determined to be less than 29.1%. A linear pharmacokinetic was revealed for cefuroxime lysine and cefuroxime sodium in dogs after intravenous infusion, and the bioequivalence of these forms of the antibiotic was observed with the significant gender-related differences in mean relative bioavailability of cefuroxime lysine versus cefuroxime sodium.

Abstract
The influence of Escherichia coli endotoxin-induced fever on the disposition of cefpirome was investigated in five male buffalo calves following a single intravenous dose of 10mgkg(-1). Blood samples were collected from 1min to 24h of drug administration. The drug concentration in plasma was estimated by microbiological assay using E. coli as a test organism. The disposition of cefpirome followed two-compartment open model and the drug was detected above the minimum inhibitory concentration in plasma up to 12h. The Vd(area) and AUC were 0.75±0.01Lkg(-1) and 35.1±0.46μgml(-1)h, respectively. The elimination half-life of 1.81±0.009h and Cl(B) of 0.29±0.004Lkg(-1)h(-1) reflected rapid elimination and body clearance of cefpirome in febrile buffalo calves. Based on the results, a satisfactory dosage regimen of cefpirome in febrile buffalo calves was calculated to be 6mgkg(-1) to be repeated at 8h intervals.

Abstract
The pharmacokinetic behavior of cefepime was studied in healthy and febrile cross-bred calves after single intravenous administration (10 mg/kg). The fever was induced with E. coli lipopolysaccharide (1 microg/kg, IV). The drug concentration in plasma was detected by microbiological assay method using E. coli (MTCC 739) test organism. Pharmacokinetic analysis of disposition data indicated that intravenous administration data were best described by 2 compartment open model. At 1 min the concentration of cefepime in healthy and febrile animals were 55.3 +/- 0.54 microg/ml and 50.0 +/- 0.48 microg/ml, respectively and drug was detected up to 12 h. The elimination half-life of cefepime was increased from 1.26 +/- 0.01 h in healthy animals to 1.62 +/- 0.09 h in febrile animals. Drug distribution was altered by fever as febrile animals showed volume of distribution (0.27 +/- 0.02 L/kg) higher than normal animal (0.19 +/- 0.01 L/kg). Total body clearances in healthy and febrile animals were 104.4 +/- 2.70 and 114.2 +/- 1.20 ml/kg/h, respectively. To maintain minimum therapeutic concentration of 1 mug/ml, a satisfactory dosage regimen of cefepime in healthy and febrile cross-bred calves would be 15.5 mg/kg and 8.2 mg/kg body weight, respectively, to be repeated at 8 h intervals. The T>MIC values (8 h) of cefepime suggested that this agent is clinically effective in the treatment of various infections.

Abstract
The pharmacokinetic behavior of marbofloxacin was studied in seven healthy goats and in the same goats with induced fever after single-dose intravenous (i.v.) administration of 2 mg/kg b.w. Fever was induced by the administration of Escherichia coli endotoxin. Drug concentration in plasma was determined by high-performance liquid chromatography (HPLC). Drug distribution was somehow altered by fever as febrile goats showed a volume of distribution at steady-state (Vss = 0.72 +/- 0.15 L/kg) lower than normal goats (Vss = 1.19 +/- 0.33 L/kg). The elimination of the drug was also modified. Total plasma clearance (Cl) decreased from 0.24 +/- 0.12 L/kg/h in healthy animals to 0.13 +/- 0.05 L/kg/h in animals with endotoxin-induced fever, which is related to an increase in the area under the plasma concentration-time curve (AUC). Consequently, mean residence time (MRT) was also slightly increased in sick animals (MRT = 5.28 +/- 00.99 and 6.09 +/- 01.45 h, in healthy and febrile animals, respectively).
