ABSTRACT

The present study was designed to assess the comparative bio-equivalence of Amikavet® and Enteropharma® in healthy broiler chicken after intramuscular injection (IM) of both products in a dose of 10 mg amikacin base/kg b.wt. Twenty four broiler chickens were divided into two groups. The first group was designed to study the pharmacokinetics of Amikavet®, while the 2nd group was designed to study the pharmacokinetics of Enteropharma®. Each broiler chicken in both groups was IM injected with 10 mg amikacin base/kg b.wt. Blood samples were obtained from the wing vein and collected immediately before and at 0.08, 0.16, 0.25, 0.5, 1, 2, 4, 8, 12 and 24 hours after a single IM injection. The disposition kinetics of Amikavet® and Enteropharma® following IM injection of 10 mg amikacin base /kg b.wt, revealed that the maximum blood concentration of amikacin [Cmax] were 14.51 and 14.13 μg/ml and attained at [tmax] of 1.95 and 1.94 hours, respectively. In conclusion: Enteropharma® is bioequivalent to Amikavet® since the ratios of Cmax, AUC0-24 and AUC0-∞ (T/R) was 0.97, 0.96 and 0.96 respectively. These are within the bioequivalence acceptance range. Enteropharma® and Amikavet® are therefore bioequivalent and interchangeable.
