Understanding how drugs behave in the body is central to effective therapy. This book explains biopharmaceutics and pharmacokinetics through topics such as drug absorption, distribution, metabolism, and excretion. It discusses the influence of dosage forms, physiological barriers, and transport mechanisms on drug bioavailability. Key pharmacokinetic parameters like half-life, volume of distribution, clearance, and steady-state concentration are presented with problem-solving exercises. The book prepares pharmacy students to analyze pharmacokinetic data and optimize therapeutic outcomes through individualized dosing.
Gillian Reid is an academic pharmacologist with a specialization in drug absorption and systemic distribution modeling. Her contributions include quantitative research on bioavailability, therapeutic index optimization, and individualized dosage calculations. She actively collaborates with bioengineers to enhance controlled-release drug platforms. Gillian has developed curriculum modules on pharmacokinetic equations and ADME principles, helping students link laboratory data with clinical interpretation. Her current projects explore biopharmaceutical classification and its role in regulatory pathways.
