Comprehensive validation scheme for in situ fiber optics dissolution method for pharmaceutical drug product testing

Area of Science:

• Pharmaceutical Science
• Analytical Chemistry
• Biomedical Engineering

Background:

• Fiber optics dissolution testing is gaining interest but limited to R&D due to a lack of validation guidelines.
• Current methods lack in situ capabilities and efficiency improvements offered by novel technologies.
• Fiber optics technology promises real-time dissolution data and enhanced testing efficiency.

Purpose of the Study:

• To develop and validate a comprehensive scheme for fiber optics dissolution testing.
• To establish a reliable, robust, reproducible, and cost-effective dissolution test using fiber optics.
• To assess the suitability of fiber optics technology for end-product release testing.

Main Methods:

• A comprehensive validation scheme was developed for fiber optics dissolution testing.
• The method was applied to a 40-mg immediate-release tablet dosage form.
• Validation parameters included linearity, precision, accuracy, specificity, and robustness (probe depth, orientation).

Main Results:

• The fiber optics dissolution test was successfully applied and validated.
• The in situ fiber optic method demonstrated comparability to traditional manual sampling methods.
• The method proved robust and reproducible across different operators and days.

Conclusions:

• Fiber optics technology can be successfully validated for dissolution and release testing.
• This validated method supports the adoption of fiber optics for end-product testing.
• Fiber optics dissolution testing offers a viable, efficient alternative to conventional methods.
