Biopharmaceutics and Pharmacokinetics Theory

Unit I

Introduction to Biopharmaceutics

Absorption; Mechanisms of drug absorption through GIT, factors influencing drug absorption through GIT, absorption of the drug from Non per oral extra-vascular routes.

Distribution Tissue permeability of drugs, binding of drugs, apparent, the volume of drug distribution, plasma and tissue protein binding of drugs, factors affecting protein-drug binding. Kinetics of protein binding, Clinical significance of protein binding of drugs

Unit II

Elimination: Drug metabolism and basic understanding metabolic pathways renal excretion of drugs, factors affecting renal excretion of drugs, renal clearance, Non-renal routes of drug excretion of drugs

Bioavailability and Bioequivalence: Definition and Objectives of bioavailability, absolute and relative bio-availability, measurement of bioavailability, in-vitro drug dissolution models, in-vitro-in-vivo correlations, bioequivalence studies, methods to enhance the dissolution rates and bioavailability of poorly soluble drugs.

Unit III

Pharmacokinetics: Definition and introduction to Pharmacokinetics, Compartment models, Non-compartment models, physiological models, One compartment open model. (a). Intravenous Injection (Bolus) (b). Intravenous infusion and (c) Extravascular administrations. Pharmacokinetics parameters – KE,t1/2,- Vd, AUC, Ka, Clt and CLR- definitions methods of eliminations, understanding of their significance and application

Unit IV

Multicompartment models: Two compartment open model. IV bolus Kinetics of multiple dosing, steady-state drug levels, calculation of loading and maintenance doses and their significance in clinical settings.

Unit V

Nonlinear Pharmacokinetics: a. Introduction, b. Factors causing Non-linearity. c. Michaelis-menton method of estimating parameters, Explanation with an example of drugs.
