[Pharmacokinetic model studies of sulfamerazine in domestic mammals. 1. Elimination of Mebacid 200 following intravenous administration to large animals].

The research conducted a Pharmacokinetic study of sulfamerazine in large domestic mammals like calves, adult cattle, horses, and sheep after administering Mebacid 200 intravenously, with the most optimal parameters observed in calves.

Objective of the Research

• This study aimed to understand the pharmacokinetics or the biochemical changes that sulfamerazine undergoes in the body of large animals, specifically calves, adult cattle, horses, and sheep.

Methodology Employed

• The veterinarian prescribed sulfamerazine containing drug, Mebacid 200 was administered intravenously to eight domestic mammals of each species.
• The reaction of the drug within these animals’ bodies was then monitored and the way the animals’ bodies absorbed, distributed, metabolised, and excreted the drug was studied.
• The elimination of the pharmaceutical substance from the animals was mathematically documented according to an exponential function c = B x e-k2 x t.

Key Findings

• The pharmacokinetics of sulfamerazine showed exponential excretion in all the species.
• The study revealed that the most favourable pharmacokinetic parameters for the elimination of sulfamerazine were observed in calves.
• The study thus suggests that the cattle’s younger age may influence the pharmacokinetics and hence, it’s elimination from their bodies.

Conclusion and Implication

• This research not only expanded the knowledge on sulfamerazine pharmacokinetics, but its effects on different domestic mammals, deepening the understanding of the relationship between age and drug metabolism in these mammals.
• The implications of this study might help in the development of more efficient and appropriate dosage schedules for different ages and species, thereby improving the health and welfare of domestic animals.
