Automated Dissolution for Enteric-Coated Aspirin Tablets: A Case Study for Method Transfer to a RoboDis II

Area of Science:

• Pharmaceutical Science
• Analytical Chemistry
• Quality Control

Background:

• Dissolution testing is labor-intensive and crucial for pharmaceutical quality control.
• Automation in dissolution testing is increasing to enhance efficiency and reduce variability.
• No official guidelines exist for transferring dissolution methods to automated systems.

Purpose of the Study:

• To effectively transfer a manual dissolution testing procedure to a fully automated system.
• To assess the feasibility and accuracy of automated dissolution testing, including media pH changes.
• To provide a systematic outline for manual-to-automated dissolution method transfer.

Main Methods:

• A manual multipoint dissolution test for enteric-coated aspirin tablets was adapted.
• The method was transferred to a fully automated dissolution testing device (RoboDis II).
• Key RoboDis II parameters were evaluated for method transfer equivalency.

Main Results:

• The manual dissolution method was successfully and reproducibly transferred to the RoboDis II.
• Automated testing accurately assessed media pH changes for enteric-coated aspirin.
• The study confirmed the integrity and equivalency of the transferred dissolution method.

Conclusions:

• Automated dissolution testers can facilitate effective and reproducible method transfer.
• The RoboDis II system is suitable for regulatory-compliant dissolution testing and method transfer.
• This study provides a framework for automating manual dissolution testing protocols.
