BIOPHARMACEUTICS AND PHARMACOKINETICS

 LPTC

3003

OBJECTIVES:
• To teach important parameters involved in drug disposition and its principles in living systems.
• To make the students to understand how the drug disposition takes place in the invitro and invivo conditions.

UNIT I

INTRODUCTION TO BIOPHARMACEUTICS

7

Definition and Role in Product Development, Explanation of the Terms: Bioavailability, and Bioequivalence, Equivalence Types: Chemical, Clinical, Therapeutic, Generic, and Pharmaceutical Alternatives. Bio-equivalency testing studies

UNIT II

PRINCIPLES OF DRUGS DISSOLUTION

11

Dissolution of solids: Mechanisms and Models of Dissolution, Factors influencing Dissolution Rate (in vitro Release), Quantitative Study of Dissolution – Methods – Dissolution of Tablets & Capsules. In vitro – In vivo correlations.


UNIT III

PRINCIPLES OF DRUG ABSORPTION AND BIO-AVAILABILITY

11

Physico – Chemical Factors: Lipid Solubility, Dissociation & pH, Complexation & Surface – active agents. Pharmaceutical Factors: Dosage Form Types and Formulation Variables Biological Factors: Passage of Drugs through Natural Membranes, Gastric Emptying & Intestinal Transition. Blood Flow, G.I. – Metabolism & Degradation, Interactions with Food & Co-administered Drugs, Disease State and Route of Administration.

UNIT IV

PHARMACOKINETICS

11

Principles of Pharmacokinetics, Concepts of Compartmental Model, Characteristics of One Compartment Model – based Pharmacokinetic Derivations (involving the concepts of (a.) Experimentally Determined Rates, (b.) Methods of Residuals and (c.) Trapezoidal Rule for the following modes of Drug Administration: Intra-Venous Administration (Plasma Level & Urinary Excretion Data)-Single Dose, Absorption Based Administration (Single Dose) - Absorption Rate Constant (ka), Elimination Rate Constant (K) & Elimination Half life (t½), AUC, Cmax, and tmax. Apparent Volume of Distribution (Vd) & Renal Clearance (Q).

UNIT V

MULTIPLE DOSAGE REGIMENS

5

Concept, Accumulation, Persistent and elimination factors. Calculation of dosage regimen following repetitive IV and oral administration

TOTAL : 45 PERIODS

OUTCOMES: The student will be able to
• Narrate the various factors influencing the drug disposition, various pharmacokinetic parameters.
• Design and interpret the dissolution studies for various dosage forms.
