Abstract: In vitro plasma protein binding studies in various animal models (Human, rat, mouse, dog, fetal calf serum) arecrucial for understanding drug behaviour and predicting human responses.These studies help determine how a drug interacts with plasma proteins, influencing its distribution, metabolism, and elimination. Protein binding significantly influences drug efficacy and safety profiles. Highly bound compounds (>90%) exhibit greater sensitivity to changes in protein levels due to disease states, age, or co-administered drugs. These data support regulatory submissions and inform clinical trial design by enabling accurate prediction of human pharmacokinetic parameters from preclinical models. The assay employs equilibrium dialysis, ultrafiltration, or ultracentrifugation methods to separate bound and unbound drug fractions, providing quantitative measurements essential for comprehensive drug development programs.
