This study evaluates risk assessment and uncertainty approximation for pharmaceutical analysis, focusing on acyclovir. Key findings highlight sample concentration and mass as major uncertainty contributors, validating a method per ICH guidelines.
Area of Science:
- Pharmaceutical Analysis
- Analytical Chemistry
- Quality Control
Background:
- Risk assessment and uncertainty approximation are crucial for reliable pharmaceutical process development.
- Traditional method validation checklists require enhancement for robust quality attribute measurement.
- A shift towards comprehensive validation is needed to ensure drug product quality.
Purpose of the Study:
- To evaluate the risk profile, combined standard uncertainty, and expanded uncertainty in acyclovir analysis.
- To validate a pharmaceutical analysis method according to ICH guidelines.
- To demonstrate the application of theoretical concepts in routine pharmaceutical analysis.
Main Methods:
- Cause-effect approach for uncertainty calculation.
- Method validation following International Council for Harmonisation (ICH) guidelines.
- Assessment of calibration model using lack-of-fit and Levene's tests.
Main Results:
- The calibration model was justified by lack of fit and Levene's test.
- Sample concentration and mass were identified as the primary contributors to uncertainty.
- The risk profile indicated potential future applications for the validated method.
Conclusions:
- The study successfully applied theoretical concepts of risk assessment and uncertainty approximation to routine pharmaceutical analysis.
- Validation using ICH guidelines and statistical tests confirmed method reliability.
- Understanding uncertainty sources is vital for accurate pharmaceutical quality assessment.
