Study Notes
Overview of Pharmaceutical Analysis
- Pharmaceutical analysis is the science of obtaining, analyzing, and quantifying drug substances.
- It is crucial for quality control, drug development, stability testing, and regulatory compliance.
Key Objectives
- Identity: Confirming the identity of drug substances.
- Purity: Assessing the absence of impurities and contaminants.
- Potency: Measuring the concentration and effectiveness of active ingredients.
- Stability: Evaluating how drug formulations change over time under various conditions.
Types of Pharmaceutical Analysis
-
Qualitative Analysis
- Determines the chemical composition or identity of a substance.
- Techniques: Thin Layer Chromatography (TLC), Infrared (IR) Spectroscopy.
-
Quantitative Analysis
- Measures the amount or concentration of a compound in a sample.
- Techniques: High-Performance Liquid Chromatography (HPLC), Mass Spectrometry (MS).
-
Physical Analysis
- Examines the physical properties of drug substances (e.g., appearance, melting point).
- Techniques: Microscopy, Thermogravimetric Analysis (TGA).
Common Techniques in Pharmaceutical Analysis
- Chromatography: Separation of components; includes TLC, HPLC, and Gas Chromatography (GC).
- Spectroscopy: Identification and quantification using light interaction; includes UV-Vis, NMR, and MS.
