Lesson 2 • Titrimetric and Gravimetric Analysis

Applies classical wet chemistry methods to quantify active ingredients and excipients. Reinforces precision and accuracy in quantitative pharmaceutical work.

Lesson 3 • Chromatographic Separation Techniques

Teaches HPLC, GC, and TLC principles and their application to purity testing. Students select stationary phases and mobile phases for specific analytes.

Lesson 4 • Impurity Profiling and Limit Testing

Identifies and quantifies process-related and degradation impurities in drug substances. Connects impurity control to patient safety and regulatory compliance.

Lesson 1 • Route Scouting and Selection

Evaluates multiple synthetic routes for an API based on cost, safety, and scalability. Students apply step economy and atom economy metrics to route comparison.

Lesson 2 • Asymmetric Synthesis Methods

Covers chiral catalysis, chiral auxiliaries, and enzymatic methods for enantioselective synthesis. Directly addresses the need for single-enantiomer APIs.

Lesson 3 • Green Chemistry in API Manufacturing

Applies the twelve principles of green chemistry to reduce waste and environmental impact. Students redesign steps using greener solvents and catalytic methods.

Lesson 4 • Scale-Up and Process Safety

Addresses heat transfer, mixing, and hazard assessment challenges when moving from lab to pilot scale. Students identify critical process parameters for safe scale-up.

Lesson 1 • Absorption and Bioavailability

Analyses routes of administration and factors governing drug absorption into systemic circulation. Connects physicochemical properties to bioavailability outcomes.

Lesson 2 • Drug Elimination and Clearance

Examines renal and biliary excretion pathways and clearance calculations. Links elimination rate to dosing interval and accumulation risk.

Lesson 3 • Phase I and Phase II Metabolism

Details cytochrome P450-mediated oxidation and conjugation reactions that transform drugs. Students predict metabolites and identify metabolic soft spots.

Lesson 4 • Drug Distribution and Protein Binding

Covers volume of distribution, tissue partitioning, and plasma protein binding. Students calculate distribution parameters and interpret clinical implications.

Lesson 1 • Formulation Stability and Shelf-Life

Applies degradation kinetics and accelerated stability testing to predict product shelf life. Students design stability protocols aligned with regulatory guidelines.

Lesson 2 • Liquid and Semi-Solid Formulations

Develops solutions, suspensions, emulsions, and topical preparations with appropriate excipients. Addresses stability, viscosity, and preservative selection.

Lesson 3 • Modified-Release Drug Delivery Systems

Designs extended-, delayed-, and controlled-release systems to optimise therapeutic profiles. Links release mechanism to polymer chemistry and membrane technology.

Lesson 4 • Preformulation Studies

Characterises API physicochemical properties before formulation development begins. Guides excipient selection and predicts compatibility issues.

Lesson 1 • Drug Development Stages Overview

Traces discovery, preclinical, and clinical phases with associated chemistry deliverables at each stage. Provides context for all prior technical chapters.

Lesson 2 • Good Manufacturing Practice Compliance

Applies GMP principles to facility design, personnel training, and quality systems. Students audit processes against GMP expectations and identify gaps.

Lesson 3 • Intellectual Property in Pharmaceuticals

Examines patent types, patent term, and exclusivity strategies relevant to drug development. Students identify patentable innovations and freedom-to-operate considerations.

Lesson 4 • Post-Market Surveillance and Pharmacovigilance

Establishes systems for monitoring adverse events and managing safety signals after approval. Connects chemistry knowledge to real-world product safety management.
