Summary
# Editorial Summary Bermingham, Davis and Whittem's 2020 synopsis addresses a critical gap in equine medicine: establishing rigorous standards for conducting pharmacokinetic (PK) studies that clinicians and researchers can reliably use to guide dosing protocols and therapeutic decisions. The authors provide a comprehensive framework covering study design fundamentals, animal selection criteria, sample collection and handling procedures, analytical methodology, and appropriate reporting standards—essentially creating a quality checklist for researchers planning PK investigations in field, clinical or laboratory settings. Key recommendations include careful consideration of drug formulation and administration route, meticulous attention to sample timing and preservation to prevent drug degradation, and transparent documentation of methodological choices that affect data validity. The practical value for equine professionals lies not only in guiding those conducting future research, but in equipping veterinarians, farriers and coaches to critically evaluate published PK data when making evidence-based decisions about medication protocols, withdrawal periods and therapeutic efficacy in their own horses. By establishing these consensus standards, the paper ultimately supports more consistent and clinically relevant drug information that can improve treatment outcomes across the discipline.

Practical Takeaways
- •When evaluating published pharmacokinetic studies in horses, critically assess the study design, sample handling procedures, and reporting transparency to determine whether results are applicable to your clinical setting.
- •If conducting your own pharmacokinetic research, consult best practice guidelines on animal selection, sampling intervals, and sample storage to ensure data validity and comparability with other studies.
- •Understand that drug formulation, route of administration, and individual horse factors significantly influence drug pharmacokinetics—published PK data may not directly translate to all clinical scenarios in your practice.
Key Findings
- •Proper study design, analytical methods, drug formulation selection, and route of administration are critical for conducting valid pharmacokinetic studies in horses.
- •Animal selection, sample collection protocols, storage and shipping procedures significantly impact the quality and reliability of pharmacokinetic data.
- •Clear reporting standards for pharmacokinetic studies enable clinicians and researchers to appraise study quality and applicability to clinical practice.
