Biopharmaceutics and Pharmacokinetics Notes: If you’re pursuing your B.Pharm and stepping into the world of Biopharmaceutics and Pharmacokinetics, this subject might feel overwhelming at first—but with the right notes, it becomes one of the most fascinating areas of pharmaceutical sciences. This guide breaks down how drugs move through the body, interact with systems, and ultimately influence therapeutic outcomes.
🔬 What Are Biopharmaceutics and Pharmacokinetics?
-
Biopharmaceutics focuses on how the formulation of a drug affects its absorption and bioavailability.
-
Pharmacokinetics (PK) is the study of how the body absorbs, distributes, metabolizes, and excretes (ADME) a drug.
These topics are foundational for understanding drug dosing, therapeutic monitoring, and optimizing treatment regimens.
🧠 Key Concepts You’ll Master
1. Drug Absorption Mechanisms
Understand how drugs pass through biological membranes and the various factors (like pH, solubility, and surface area) that influence absorption.
2. Distribution and Plasma Binding
Explore how drugs travel through the bloodstream, bind to proteins like albumin, and distribute across different body tissues.
3. Metabolism & Elimination
Learn about enzymatic metabolism (especially in the liver) and how kidneys excrete drugs—and why this matters for dose adjustments.
4. Pharmacokinetic Models
Dive into compartment models (one- and two-compartment systems), half-life, clearance, volume of distribution, and how they affect drug dosing.
5. Bioavailability & Bioequivalence
Understand what makes a drug available at the site of action and how generics are compared with branded drugs to ensure equal efficacy.
