Abstract
A pharmacokinetic study of ceftiofur crystalline free acid sterile oil suspension (CCFA) was performed in six apparently healthy juvenile American alligators (Alligator mississippiensis). A single intramuscular dose of 30 mg/kg was administered in the triceps muscle. Blood samples were collected prior to treatment and at 4, 12, 24, 48, 72, 120, 144, 192, 288, and 366 h post administration. Plasma samples were analyzed for ceftiofur equivalent concentrations using liquid chromatography-mass spectrometry. Pharmacokinetic parameters were determined by noncompartmental analysis. Mean peak plasma concentration was 23.2 µg/ml (range, 16.0-27.9), median time to maximum concentration was 72 h (range, 72-120), mean area under the curve from 0 to 366 h postdose was 4.24 h · mg/ml (range, 3.54-4.97), and mean terminal half-life was 143 h (range, 90.8-220). Plasma concentrations were maintained above the minimum inhibitory concentration for this study of 2.0 µg/ml, which was established from similar CCFA pharmacokinetic studies in other reptilian species, through the end of the data collection of 366 h. Because of prolonged plasma concentrations, a dosing interval could not be established in this study. Future studies should include extended collection time points and multidose studies to determine dosing regimens.

Pharmaceutics 2021; 13:pharmaceutics13111804. [PMID: 34834219 PMCID: PMC8622898 DOI: 10.3390/pharmaceutics13111804] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2021] [Revised: 10/21/2021] [Accepted: 10/24/2021] [Indexed: 12/15/2022] Open
Abstract
The bioavailability and pharmacokinetics in turkeys of cefquinome (CFQ), a broad-spectrum 4th-generation cephalosporin antibiotic, were explored after a single injection of 2 mg/kg body weight by intravenous (IV) and intramuscular (IM) routes. In a crossover design and 3-weeks washout interval, seven turkeys were assigned for this objective. Blood samples were collected prior to and at various time intervals following each administration. The concentration of CFQ in plasma was measured using HPLC with a UV detector set at 266 nm. For pharmacokinetic analysis, non-compartmental methods have been applied. Following IV administration, the elimination half-life (t1/2ʎz), distribution volume at steady state (Vdss), and total body clearance (Cltot) of CFQ were 1.55 h, 0.54 L/kg, and 0.32 L/h/kg, respectively. Following the IM administration, CFQ was speedily absorbed with an absorption half-life (t1/2ab) of 0.25 h, a maximum plasma concentration (Cmax) of 2.71 μg/mL, attained (Tmax) at 0.56 h. The bioavailability (F) and in vitro plasma protein binding of CFQ were 95.56% and 11.5%, respectively. Results indicated that CFQ was speedily absorbed with a considerable bioavailability after IM administration. In conclusion, CFQ has a favorable disposition in turkeys that can guide to estimate optimum dosage regimes and eventually lead to its usage to eradicate turkey's susceptible bacterial infections.

Abstract
Ceftiofur, a third-generation cephalosporin antibiotic, is being extensively used by pet doctors in China. In the current study, the detection method was developed for ceftiofur and its metabolites, desfuroylceftiofur (DCE) and desfuroylceftiofur conjugates (DCEC), in feline plasma. Then, the pharmacokinetics studies were performed following one single intravenous and subcutaneous injection of ceftiofur sodium in cats both at 5 mg/kg body weight (BW) (calculated as pure ceftiofur). Ceftiofur, DCE, and DCEC were extracted from plasma samples, then derivatized and further quantified by high-performance liquid chromatography. The concentrations versus time data were subjected to noncompartmental analysis to obtain the pharmacokinetics parameters. The terminal half-life (t1/2λz ) was calculated as 11.29 ± 1.09 and 10.69 ± 1.31 hr following intravenous and subcutaneous injections, respectively. After intravenous treatment, the total body clearance (Cl) and volume of distribution at steady-state (VSS ) were determined as 14.14 ± 1.09 ml hr-1 kg-1 and 241.71 ± 22.40 ml/kg, respectively. After subcutaneous injection, the peak concentration (Cmax ; 14.99 ± 2.29 μg/ml) was observed at 4.17 ± 0.41 hr, and the absorption half-life (t1/2ka ) and absolute bioavailability (F) were calculated as 2.83 ± 0.46 hr and 82.95%±9.59%, respectively. The pharmacokinetic profiles of ceftiofur sodium and its related metabolites demonstrated their relatively slow, however, good absorption after subcutaneous administration, poor distribution, and slow elimination in cats. Based on the time of drug concentration above the minimum inhibitory concentration (MIC) (T>MIC) calculated in the current study, an intravenous or subcutaneous dose at 5 mg/kg BW of ceftiofur sodium once daily is predicted to be effective for treating feline bacteria with a MIC value of ≤4.0 μg/ml.

Abstract
The purpose of this study was to evaluate the bioequivalence of 5% ceftiofur
hydrochloride sterile suspension in two formulations, a test formulation (Saifukang 5%
CEF, Hvsen) and a reference formulation (Excenel®RTU 5% CEF, Pfizer). Twenty-four healthy
pigs were assigned to a two-period, two-treatment crossover parallel trial, and both
formulations were administered at a single intramuscular dose of 5 mg/kg weight, with a
7-day washout period. Blood samples were collected consecutively for up to 144 hr after
administration. The concentrations of ceftiofur- and desfuroylceftiofur-related
metabolites in the plasma were determined by high-performance liquid chromatography. In
addition, the major pharmacokinetic parameters (Cmax, AUC0-t and
AUC0-∞) were computed and compared via analysis of variance, with 90%
confidence intervals. Bioequivalence evaluation of Tmax was statistically
analyzed with the nonparametric test. The comparison values between test and reference
formulation for AUC0-t, AUC0-∞, Cmax, and Tmax
were 376.7 ± 75.3 µg·hr/ml, 390.5 ±
78.6 µg·hr/ml, 385.9 ± 79.2
µg·hr/ml, 402.7 ± 80.4
µg·hr/ml, 34.6 ± 5.5
µg/ml, 36.1 ± 6.2
µg/ml, 1.27 ± 0.18 hr, and 1.26 ±
0.21 hr, respectively, and we observed no significant differences between the two
formulations. The 90% CI values were within the recommended range of 80–125%
(P>0.05), and the relative bioavailability of the test product was
96.47 ± 10.92% according to AUC0-t values. Based on our results, the two
formulations exhibit comparable pharmacokinetic profiles, and the test product is
bioequivalent to the reference formulation.

A novel method for synthesis of α-spinasterol and its antibacterial activities in combination with ceftiofur. Fitoterapia 2017; 119:12-19. [PMID: 28351722 DOI: 10.1016/j.fitote.2017.03.011] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2017] [Revised: 02/28/2017] [Accepted: 03/10/2017] [Indexed: 01/23/2023]
Abstract
In this study, we designed a novel method of the synthesis of α-spinasterol from commercially available stigmasterol and explored the combinational effect of the α-spinasterol with ceftiofur in vitro against S. pullorum cvcc533, S. pneumoniae CAU0070, E. coli, and S. aureus. α-Spinasterol was obtained by a key reaction of Bamford-Stevens reaction with a desirable yield for five steps. The combination of α-spinasterol and ceftiofur showed stronger synergetic effect against the four pathogenic strains compared with that of stigmasterol and ceftiofur alone. In time-kill analyses, at concentrations above the MICs, ceftiofur in combination with α-spinasterol exhibited time-dependency and concentration-dependency comparing to time dependency with ceftiofur alone. We conclude that the combination usage of α-spinasterol and ceftiofur is an effective and promising strategy against the four pathogenic bacterial strains in vitro.
