# Pharmacokinetics of Antibiotics in Crocodiles: A Review

## TL;DR

This review highlights the challenges in antibiotic dosing for crocodiles due to species-specific pharmacokinetic differences and calls for more research to improve treatment safety and effectiveness.

## Contribution

The paper emphasizes the need for species-specific pharmacokinetic studies to develop standardized antibiotic dosing in crocodiles.

## Key findings

- Pharmacokinetic variability exists among crocodilian species, affecting drug absorption, distribution, metabolism, and elimination.
- Environmental factors like temperature significantly influence antibiotic pharmacokinetics in crocodiles.
- Limited pharmacological data and standardized dosing regimens increase the risk of under- or over-dosing in clinical and conservation settings.

## Abstract

Antibiotics are used to treat bacterial infections in crocodiles; however, determining appropriate dosing regimens remains challenging due to interspecies variations in pharmacokinetics and the limited availability of pharmacological data. This review critically examined the commonly used antibiotics, their therapeutic efficacy, and the factors influencing optimal dosage. It identified the need for further pharmacokinetic (PK) and pharmacodynamic (PD) research to refine dosing strategies, thereby improving treatment outcomes and minimizing the risk of adverse effects.

This review aims to provide an overview of the pharmacokinetics of antibiotics in crocodilian species, focusing on species-specific variations in drug absorption, distribution, metabolism, and elimination (ADME), as well as the influence of environmental factors. A review of the available literature across crocodilian species reveals notable pharmacokinetic variability. Environmental influences, such as temperature and metabolic rate, are shown to impact these pharmacokinetic parameters significantly. Despite the frequent use of antibiotics in clinical and conservation settings, the lack of standardized dosing regimens presents risks of under- or over-dosing. This variability is compounded by limited research on species-specific drug metabolism and elimination processes. The review highlights the need for further pharmacokinetic studies to develop evidence-based dosing protocols, optimize therapeutic outcomes, and address concerns related to antimicrobial resistance. Future research should focus on filling the gaps in PK data to refine dosing strategies and ensure both efficacy and safety in crocodilian species.
