Abstract
Physiologically Based Biopharmaceutical Models (PBBMs) are advanced tools that integrate physiological parameters with drug-specific properties to simulate drug behavior in vivo. In this study, we present the development of a PBBM specifically tailored for felodipine prolonged-release (PR) tablet formulations. Felodipine, a potent calcium channel blocker, is widely used for the treatment of hypertension and angina pectoris. Prolonged-release formulations aim to provide controlled drug release, ensuring sustained therapeutic effect with reduced dosing frequency and minimized adverse effects. Our PBBM incorporates key physiological processes such as gastrointestinal transit, drug dissolution, absorption, distribution, metabolism, and elimination. Data from in vitro dissolution studies, preclinical pharmacokinetics, and clinical observations are integrated to parameterize the model accurately. Special attention is given to the physicochemical properties of felodipine and the release characteristics of the PR tablet formulation. Validation of the PBBM is conducted against clinical pharmacokinetic data obtained from bioequivalence studies and population pharmacokinetic analyses of felodipine PR tablets. The model may demonstrate excellent predictive performance, accurately capturing plasma concentration-time profiles across different dosing regimens and patient populations. The developed PBBM provides valuable insights into the biopharmaceutical behavior of felodipine PR tablets, facilitating rational formulation design, dosage regimen optimization, and therapeutic individualization. It serves as a powerful tool for drug developers, regulatory agencies, and clinicians to enhance the efficiency and effectiveness of drug development and clinical pharmacotherapy
