This study aimed to examine the pharmacokinetic changes in tolfenamic acid administered intravenously and orally to ducks at different doses (2, 4, and 8 mg/kg). Furthermore, the binding ratio to plasma proteins was assessed utilizing the ultrafiltration method. Eighteen male Pekin ducks were randomly assigned to three dosage groups (2, 4, and 8 mg/kg), with each group undergoing a trial in two phases: intravenous (IV) and oral administration.

Article Synopsis
  • Danofloxacin, a fluoroquinolone antibiotic, is effective against bacterial infections in fish, but its pharmacokinetics vary based on fish size, impacting its medicinal effectiveness.!* -
  • A study conducted on rainbow trout demonstrated that larger fish have higher plasma concentrations and overall drug efficacy of danofloxacin compared to smaller fish, with measurements taken after oral administration.!* -
  • While larger fish show increased therapeutic efficacy, their higher drug concentrations in tissues raise concerns about potential residue and withdrawal time for safe consumption.!*

Objective: This study aimed to investigate the plasma and milk pharmacokinetics, as well as the withdrawal time (WT) from milk of tolfenamic acid (2 and 4 mg/kg) following intravenous (IV) administration to eight healthy lactating Akkaraman sheep.

Methods: The trial was conducted in two periods in accordance with a crossover pharmacokinetic design. The concentrations of tolfenamic acid in the plasma and milk were determined using high-pressure liquid chromatography and evaluated using non-compartmental analysis.

Article Synopsis
  • The study aimed to examine how the pharmacokinetics of marbofloxacin varies with the age of calves after a single IV dose of 10 mg/kg.
  • It involved Montofon calves of different ages (1, 2, and 4 months), measuring plasma concentrations and calculating pharmacokinetic parameters like half-life, volume of distribution, total clearance, and area under the curve (AUC) using HPLC.
  • Findings indicated that as calves age, the elimination half-life and AUC decrease while total clearance increases, suggesting that the effectiveness of marbofloxacin may decline with age, calling for a reevaluation of the dosing strategy based on the bacteria's minimum inhibitory concentration (MIC) values.

Carprofen can be used in the castration process of male goats due to its low side effects, long elimination half-life, and long-term effect. However, no studies were found on the pharmacokinetics and physiological efficacy of carprofen when employed for castration in male goats. The aim of this study was to determine the effect of xylazine (0.

The purpose of this study was to compare the pharmacokinetics, tissue residues, and withdrawal times of doxycycline after oral administration in rainbow trout reared at 10 and 17 °C. Fish received a 20 mg/kg oral dose of doxycycline after a single or 5-day administration. Six rainbow trout were used at each sampling time point for plasma and tissue samples, including liver, kidney, and muscle and skin.
