Population Pharmacokinetics of Doxycycline, Administered Alone or with N-Acetylcysteine, in Chickens with Experimental Mycoplasma gallisepticum Infection. Pharmaceutics 2022; 14:pharmaceutics14112440. [PMID: 36432632 PMCID: PMC9693581 DOI: 10.3390/pharmaceutics14112440] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 10/25/2022] [Accepted: 11/08/2022] [Indexed: 11/16/2022] Open
Abstract
Mycoplasmosis is a bacterial infection that significantly affects poultry production, and it is often controlled with antibiotics, including doxycycline. The conducted study aimed to determine population pharmacokinetic (PopPk) parameters of doxycycline in healthy (n = 12) and in Mycoplasma gallisepticum-challenged (n = 20) chickens after its oral administration via drinking water at the registered dose rate of 20 mg/kg b.w./24 h for five days, without or with co-administration of N-acetylcysteine (NAC, a dose of 100 mg/kg b.w./24 h) via the feed. Doxycycline concentrations in plasma were analyzed with the LC-MS/MS method. The values of tvV/F and tvke were 4.73 L × kg−1 and 0.154 h−1, respectively, and they showed low BSV. A high BSV of 93.17% was calculated for the value of tlag of 0.8 h, which reflects the inter-individual differences in the water consumption. PTA was computed after Monte Carlo simulation with the registered dose for doxycycline. The target of %fT > MIC ≥ 80% and 100% can be achieved in 90% of the broiler population, after a correction for protein binding, for bacteria with MIC ≤ 0.5 mg × L−1 and 0.25 mg × L−1, respectively. The applied PopPk model did not reveal significant effect of M. gallisepticum infection and co-administration of NAC on pharmacokinetic parameters of doxycycline.

Sartini I, Łebkowska-Wieruszewska B, Lisowski A, Poapolathep A, Sitovs A, Giorgi M. Doxycycline pharmacokinetics in geese. J Vet Pharmacol Ther 2021; 44:975-981. [PMID: 34318509 PMCID: PMC9291109 DOI: 10.1111/jvp.13002] [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: 05/17/2021] [Revised: 06/28/2021] [Accepted: 07/13/2021] [Indexed: 11/30/2022]
Abstract
The study aims to describe the pharmacokinetics of doxycycline after a single intravenous and oral dose (20 mg/kg) in geese. In addition, two multiple‐dose simulations have been performed to investigate the predicted plasma concentration after either a 10 or 20 mg/kg daily administration repeated consecutively for 5 days. Ten geese were enrolled in a two‐phase cross‐over study with a washout period of two weeks. All animals were treated intravenously and orally with doxycycline, and blood samples were collected up to 48 h after drug administration. Sample analysis was performed using a validated HPLC‐UV method. A non‐compartmental approach was used to evaluate the pharmacokinetic parameters of the drug. A long elimination half‐life was observed (13 h). The area under the curve was statistically different between the two treatments, with the oral bioavailability being moderate (43%). The pharmacokinetic/pharmacodynamic index (%T>MIC) during the 48 h treatment period in the present study (71%) suggests that doxycycline appears to have therapeutic efficacy against some Mycoplasma species in the goose. The multiple‐dose simulations showed a low accumulation index. A dosage of 10 mg/kg/day for 5 days seemed to be adequate for a good therapeutic efficacy without reaching unnecessarily high plasma concentrations.

Development and Application of a Water Temperature Related Physiologically Based Pharmacokinetic Model for Enrofloxacin and Its Metabolite Ciprofloxacin in Rainbow Trout. Front Vet Sci 2021; 7:608348. [PMID: 33585600 PMCID: PMC7874017 DOI: 10.3389/fvets.2020.608348] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2020] [Accepted: 12/31/2020] [Indexed: 01/21/2023] Open
Abstract
Enrofloxacin (ENR) has been approved for the treatment of infections in aquaculture, but it may cause tissue residue. This research aimed to develop and validate a water temperature related PBPK model, including both ENR and ciprofloxacin (CIP), in rainbow trout, and to predict further their residue concentrations and the withdrawal periods for ENR at different water temperatures. With the published concentrations data, a flow-limited PBPK model including both ENR and CIP sub-models was developed to predict ENR and CIP concentrations in tissues and plasma/serum after intravenous, oral, or immersion administration. A Monte Carlo simulation including 500 iterations was further incorporated into this model. Based on the model and Monte Carlo analysis, the withdrawal intervals were estimated for different dosage regimens and at different water temperatures, ranging from 80 to 272 degree-days. All of these values were shorter than the labeled withdrawal period (500 degree-days) in fish. This model provided a useful tool for predicting the tissue residues of ENR and CIP in rainbow trout under different dosage regimens and at different water temperatures.

Abstract
This study aimed to determine the bioavailability, tissue residue and withdrawal time of doxycycline after oral administration in Japanese quails (Coturnix coturnix japonica). Japanese quails received doxycycline at 20 mg/kg dose following either single intravenous or oral administration, or 5-day oral administration. Doxycycline concentrations in plasma, liver, kidney, muscle, and skin + fat were determined using high-performance liquid chromatography-ultraviolet. The Withdrawal Time v1.4 software was used to calculate withdrawal times. Following single oral administration, terminal elimination half-life, area under the concentration-time curve from 0 to infinitive time, peak plasma concentration (Cmax) and time to reach Cmax were 10.98 h, 215.84 (h*µg)/mL, 15.33 μg/mL, and 2 h, respectively. The oral bioavailability was 25.84% in quails. In this study, the mean doxycycline concentration was below the maximum residue limit (MRL) at day 4 in skin + fat (0.120 µg/g), and at day 5 in kidney (0.41 µg/g), liver (0.26 µg/g), and muscle (<0.05 µg/g lowest limit of quantification). The highest concentrations of doxycycline after 5-day oral administration were found in kidney compared with other tissues and plasma. These results indicate that the withdrawal times required for doxycycline to reach concentrations <MRLs after 5-day oral administration at 20 mg/kg dose in Japanese quail are 6 days in Europe and China and 9 days in Japan.

Abstract
The present study aimed to determine the pharmacokinetic profiles of ceftiofur (as measured by ceftiofur and its active metabolites concentrations) in a small-size dog breed, Peekapoo, following a single intravenous or subcutaneous injection of ceftiofur sodium. The study population comprised of five clinically healthy Peekapoo dogs with an average body weight (BW) of 3.4 kg. Each dog received either intravenous or subcutaneous injection, both at 5 mg/kg BW (calculated as pure ceftiofur). Plasma samples were collected at different time points after the administration. Ceftiofur and its active metabolites were extracted from plasma samples, derivatized, and further quantified by high-performance liquid chromatography. The concentrations versus time data were subjected to noncompartmental analysis to obtain the pharmacokinetic parameters. The terminal half-life (t1/2 λz ) was calculated as 7.40 ± 0.79 and 7.91 ± 1.53 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 39.91 ± 4.04 ml hr-1 kg-1 and 345.71 ± 28.66 ml/kg, respectively. After subcutaneous injection, the peak concentration (Cmax ; 10.50 ± 0.22 μg/ml) was observed at 3.2 ± 1.1 hr, and the absorption half-life (t1/2 ka ) and absolute bioavailability (F) were calculated as 0.74 ± 0.23 hr and 91.70%±7.34%, respectively. The pharmacokinetic profiles of ceftiofur and its related metabolites demonstrated their quick and excellent absorption after subcutaneous administration, in addition to poor distribution and slow elimination in Peekapoo dogs. Based on the time of concentration above minimum inhibitory concentration (T > MIC) values calculated here, an intravenous or subcutaneous dose at 5 mg/kg of ceftiofur sodium once every 12 hr is predicted to be effective for treating canine bacteria with a MIC value of ≤4.0 μg/ml.

J Vet Pharmacol Ther 2020; 43:179-188.

Abstract
Biopharmaceutics Classification System (BCS) has gained broad acceptance in promoting the development of human drugs. To date, the applicability of existing human BCS criteria has not been evaluated in chickens. The objective of this study was to discuss the feasibility of BCS extrapolation between species and establish a preliminary chicken BCS by classifying seven veterinary commonly used drugs including metronidazole, amoxicillin, sulfamethoxazole, sulfadiazine, ciprofloxacin hydrochloride, doxycycline hydrochloride, and trimethoprim. Firstly, we finished the determination of physiological parameters affecting solubility in chickens, including body temperature, gastrointestinal pH, and the fluid volume in the gastrointestinal tract (GI), and the drug is considered highly soluble in chicken BCS when the highest dose strength is soluble in 20.40 ml (fed) or 6.73 ml (fasted) over the pH range of 1-8 at 41°C. Drug solubility classification was based on dose number calculation. Metronidazol and amoxicillin were classed differently under fed and fasted conditions. Secondly, we discussed the effect of ABC transporters (MDCK vs. MDCK-chAbcb1/Abcg2) and pH (5.5 vs. 7.4) on drug permeability and classification. The drug is classified as highly permeable when its permeability is equal to or greater than metoprolol tartrate. Though ABC transporters and pH significantly affected the permeability values of drugs (p < .05), the permeability classification of the drugs has not been changed except for sulfamethoxazole. This work highlights some of the significant challenges that would be encountered in order to develop a chicken BCS, this valuable information could serve as a helpful tool during chicken drugs development and to minimize the potential risks when developing formulations.

Abstract
The previously adopted marker residue for florfenicol (FF) in China was only florfenicol amine (FFA); however, the marker residue has been changed to FF plus FFA since the end of 2017. The previous official withdrawal period determined based on the only concentration of FFA may no longer be suitable. Therefore, the present study aimed to determine the depletion profiles of FF and FFA and further calculate the withdrawal period in the crucian carp (Carassius auratus) based on the new marker residues. Florfenicol was intramuscularly administered at 10 mg/kg bodyweight daily for five consecutive days to crucian carps reared in freshwater at 10°C. After the last dose, plasma and tissue samples were randomly collected from 10 fish at different time points. The FF and FFA concentrations were simultaneously determined by high-performance liquid chromatography (HPLC) with a fluorescence detector and further subjected to noncompartmental analysis. The elimination half-life (h) of FF in different tissues decreased as follows: liver (39.1) > kidney (36.3) > skin plus muscle (34.6) > plasma (31.7), whereas that of FFA decreased as follows: kidney (41.4) > skin plus muscle (39.4) > liver (39.3) > plasma (35.7). Considering a maximum residue limit of 1 μg/g for the total concentration of FF and FFA in the skin plus muscle, a withdrawal period of 6 days was calculated based on the upper limit of the one-sided 95% confidence interval.

Abstract
The problem of processing, use and utilization of poultry manure contaminated with antibiotics remains unsolved not only Ukraine but around the world, and theatment and prevention of highly contagious infectious diseases among birds requires antibacterial medication use. By liquid chromatography, 293 hen manure samples of 12 Ukrainian industrial flocks of poultry farms were studied. The residual content of 9 antibiotics in the hen manure was found, including 38.2% of tetracycline preparations (doxycycline, oxytetracycline, tetracycline and chlortetracycline), fluoroquinolone (enrofloxacin and norfloxacin) including combinations of incompatible tetracyclines and fluoroquinolones, broad-spectrum penicillins (amoxicillin), fenicols (florfenicol), macrolides (tylosin) and one sulfanilamide preparation (sulfametazine). The most common antibiotics in hen manure of Ukrainian industrial flocks of poultry farms are the antibiotics of the tetracycline group, the main one being doxycycline. A high correlation was determined between the release of doxycycline with eggs and hen manure after the preparation was used perorally in preventive and therapeutic doses. Time of complete excretion of doxycycline from the hen body at the preventive dose (50 mg/L of water for 7 days) was 14 days for manure, 8 days for eggs, following its withdrawal, and at the therapeutic dose (100 mg/L of water for 7 days ) – 20 days for manure, and 9 days for eggs, following its withdrawal. The perspective of using the obtained data about the duration of excretion of doxycycline with hen manure consists in confirmation of the time of the antibiotic’s excretion with manure following its use for preventive or therapeutic purpose, which will help in controlling it as a source of environmental pollution. The time of doxycycline excretion from the body of hens with eggs and manure may be used practically by professionals in veterinary medicine in the case of prescribing or replacing antibiotics for treatment of infectious diseases of poultry to prevent the combination of incompatible preparations in the body and manure. The obtained experimental data may form the basis for the development of national regulations on the processing, usage and utilization of manure of hens under treatment with antibiotics.

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
We examined the tissue distribution and elimination of quinocetone (QCT) and its major metabolites 1-desoxyquinocetone (1-DQCT), di-desoxyquinocetone (BDQCT), and 3-methyl-quinoxaline-2-carboxylic (MQCA) in ducks. The analytes were simultaneously quantitated using a UPLC-MS/MS method after oral administration of QCT at 100 mg·kg-1 day-1 for 7 days. We found that QCT and its major metabolites were widely distributed in duck tissues. The concentrations indicated that the primary compound in the liver, kidney, and heart was MQCA and the primary compound in the stomach, intestine, spleen, and lung was QCT. We also identified that MQCA was the most appropriate compound for QCT residue monitoring. The liver and kidney are the primary QCT target organs in ducks, and this study provides clear monitoring tools and important data to evaluate its safety.

The study was carried out to evaluate the pharmacokinetic disposition of enrofloxacin (ENF) with a single dose of 20 mg/kg after oral administration in largemouth bass (Micropterus salmoides) at 28°C. The concentrations of ENF and of its metabolite ciprofloxacin (CIP) in plasma, liver, and muscle plus skin in natural proportions were determined using HPLC. The concentration-time data for ENF in plasma were best described by a two-compartment open model. After oral administration, the maximum ENF concentration (Cmax ) of 10.99 μg/ml was obtained at 0.60 hr. The absorption half-life (T1/2Ka ) of ENF was calculated to be 0.07 hr whereas the elimination half-life (T1/2β ) of the drug was 90.79 hr. The estimates of area under the plasma concentration-time curve (AUC) and apparent volume of distribution (Vd/F) were 1,185.73 μg hr/ml and 2.21 L/kg, respectively. ENF residues were slowly depleted from the liver and muscle plus skin of largemouth bass with the T1/2β of 124.73 and 115.14 hr, respectively. Very low levels of ciprofloxacin were detected in the plasma and tissues. A withdrawal time of 24 days was necessary to ensure that the residues of ENF + CIP in muscle plus skin were less than the maximal residue limit (MRL) of 100 μg/kg established by the European Union.

Tissue residue depletion kinetics and withdrawal time estimation of doxycycline in grass carp, Ctenopharyngodon idella, following multiple oral administrations. Food Chem Toxicol 2019; 131:110592. [PMID: 31220539 DOI: 10.1016/j.fct.2019.110592] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2019] [Revised: 06/12/2019] [Accepted: 06/14/2019] [Indexed: 12/15/2022]
Abstract
This study aimed to determine the plasma and tissue residue depletion kinetics of doxycycline (DC) in grass carp (Ctenopharyngodon idella) after daily oral administrations at 20 mg/kg for 3 days, and to calculate the corresponding withdrawal times. Following drug administrations, samples of plasma, liver, kidney, gill and muscle + skin were collected at predetermined time points (0.25, 0.5, 1, 3, 5, 7, 14, 21, 28, 35, 42, 49 and 56 days) and analyzed for concentrations of DC using a LC-MS/MS method. The results showed that liver had the highest concentrations and the slowest depletion compared to other tissues, with detectable DC up to 49 days (58.9 ± 12.8 μg/kg). The WT 1.4 software and "reschem" package were used to calculate withdrawal times, and the results were similar. The results suggest a withdrawal time of 41 days for Europe and China and 50 days for Japan is needed for DC in grass carp after 3 daily oral administrations at 20 mg/kg. Overall, this study improves our understanding of the tissue residue depletion kinetics of DC in fish, and the results may help regulatory agencies to determine proper withdrawal periods based on different regulatory standards in different countries to ensure safety of aquatic food products.

Abstract
The pharmacokinetic properties of amoxicillin (AMX) and clavulanic acid (CLV) were studied in healthy cats following single intravenous and oral dosage of 10 mg/kg of AMX and 2.5 mg/kg of CLV. The drug concentrations in plasma were determined by a high-performance liquid chromatographic-tandem mass spectrometry (LC-MS-MS) method validated for canine plasma and further subjected to noncompartmental analysis. After intravenous injection, no significant difference (p > 0.05) was found in the volume of distribution of these two compounds. In addition, AMX and CLV were both rapidly eliminated from plasma with a clearance of 0.453 and 0.921 L hr-1 kg-1 , respectively; however, a quicker elimination was observed for CLV (p < 0.01). After oral administration, both drugs were characterized by rapid absorption with an absorption half-life of 1.10 and 0.70 hr for AMX and CLV, respectively. Significant differences were observed between their absorption rates (p < 0.05). However, the oral bioavailabilities of AMX and CLV (75.57% and 98.15%, respectively) were not statistically different (p > 0.05). A total intravenous or oral dose at 12.5 mg/kg of AMX and CLV (4:1) is predicted to be effective for treating those bacterial species isolated from cats with a minimum inhibitory concentration (MIC) of ≤0.25 μg/ml for 12 hr, based on a time above the MIC (T > MIC) of 40%.

Abstract
The bioavailability and pharmacokinetic disposition of tiamulin in broiler chicken were investigated after administration through the crop, drinking water, and feed at 40 mg/kg body weight. Residues of tiamulin in tissues of broiler chicken were also assessed. Plasma and tissue concentrations of tiamulin were analyzed by reverse-phase high-performance liquid chromatography (HPLC) method. Plasma concentration-time data were described by the non-compartmental model for all three routes, and pharmacokinetic parameters were calculated. There were no significant differences (p > 0.05) in pharmacokinetic parameters and mean plasma concentrations of tiamulin between three routes tested (crop, water, and feed), indicating equal efficacy. Tiamulin residues in edible tissues (muscles, skin, and fat) were lower than the advocated maximum residue limit (MRL of 0.1 µg/g and that of liver was 1 µg/g) on the 3rd day. No traces were found on the 5th day after drug administration. This indicated that the withdrawal period (less than 5 days) is very short, which makes it safer. This study shows that tiamulin can be used with equal efficacy through all routes of administration in broiler chicken (crop, water, and feed).

Abstract
As a semisynthetic tetracycline derivative, doxycycline (α-6-deoxy-5-hydroxytetracycline) is a time-dependent bacteriostatic agent. It is being widely used in the broiler husbandry in China. In this study, doxycycline was orally administered by gavage to 10 healthy broiler chickens at the dose of 20 mg/kg body weight every 24 hr for five total treatments. Plasma samples were collected from each animal at 5, 10, 20, and 30 min and 1, 2, 4, 6, 8, and 12 hr after the first dose, at 0.25, 0.5, 0.45, 1, 2, 3, 4, 6, 7, 13.5, 24, 36, 48, 60, and 72 hr after the last dose. Additional plasma samples were collected at a 24-hr interval during the dosing period (immediately prior to each oral administration). The doxycycline concentrations were determined by high-performance liquid chromatography with an ultraviolet detector and subjected to noncompartmental analysis. Then, the pharmacokinetics profiles were compared after the first and last oral doses. After the first dosing, the elimination half-life, area under the concentration-time curve from 0 hr to ∞, peak concentration, time to reach peak concentration, and volume of distribution per fraction absorbed were determined as 7.78 hr, 94.19 μg·hr/ml, 5.65 μg/ml, 3.50 hr, and 2,502.65 ml/kg, respectively, while the corresponding values of these parameters after the last dose were 19.90 hr, 121.08 μg·hr/ml, 5.71 μg/ml, 7.25 hr, and 5,285.28 ml/kg, respectively. After multiple oral doses, the absorption and elimination both became slower, while the distribution was more extensive than that following a single dose. However, after multiple oral doses, accumulation of doxycycline in plasma was not observed with an average accumulation factor of 1.11.

Abstract
Abstract
The pharmacokinetics of doxycycline was investigated in force-fed and normally fed ducks after single intravenous (i.v.) and oral (p.o.) administration at a dose of 15 mg/kg bw. Serum concentrations of the drug were determined by the HPLC method. Pharmacokinetic parameters were calculated using compartmental analysis. Serum concentrations of doxycycline after i.v. administration in both groups were not statistically different. The values of half-lives were 5.82±1.85 h and 6.06±5.51 h in normal and force-fed birds. The total body clearance was respectively 0.40±0.05 L/h/kg and 0.34±0.10 L/h/kg, and volume of distribution (Vss) was 2.80±0.85 L/kg and 2.18±0.89 L/kg. After p.o. administraton the maximum serum levels in the control group were 0.70±0.12 μg/mL and in force-fed birds were 1.93±0.32 μg/mL, measured at 2.95±0.60 h and 1.45±0.24 h, respectively. The values of absolute bioavailability were 18.89±6.48% and 37.58±13.63%. Longer doxycycline retention in force-fed ducks was registered. Our data can be accepted as an information for possible prolonged retention of doxycycline in force fed ducks compared to normally fed ones.
