Biopharmaceutical Considerations
Start with the big picture
Biopharmaceutics links properties such as solubility, ionization, dissolution, and stability to in vivo ADME and dosage-form performance. For oral absorption, the lesson considers how aqueous solubility, membrane permeability, and dissolution rate can shape drug uptake. It introduces the BCS as a framework for considering whether dissolution or permeability is the main formulation challenge, and examines the roles of pKa, dose-to-solubility balance, particle size, salt form, and solid-state form. Further topics include lipid-based formulations, permeability strategies, first-pass metabolism, excipient effects, modified release, food effects, bioavailability and IVIVC, stability, and patient factors. Together, these concepts show how formulation choices can address biopharmaceutical limitations.
