Join this webinar to understand why mechanical calibration alone may not be sufficient to fully qualify dissolution testing equipment - and learn from experts how USP’s improved Dissolution Performance Verification Standard (DPVS) reduces variability and increases confidence in results.
This webinar will review how dissolution and drug release testing are used to demonstrate the consistency of pharmaceutical product performance within and across batches of critical medicines. Learn from USP experts the importance of fully qualifying dissolution testing equipment. Understand the rationale for developing a new formulation used for the performance verification test (PVT) mentioned in USP General Chapter <711> Dissolution.
See USP data that demonstrates the improved sensitivity of USP’s PVT reference standard- the dissolution performance verification standard (DPVS). Understand the risks of choosing an either-or approach when it comes to considering mechanical calibration and performance verification testing (PVT) for dissolution instrument qualification procedures.
Key learning points:
- Rigorous development of the USP DPVS
- Potential sources of variability in dissolution testing related to equipment operation and setup
- Risks and implications of relying solelt on mechanical calibration or PVT
- Criteria for a ‘fully qualified’ dissolution instrument according to USP specifications
- Impact of choosing an ‘either-or’ approach for mechanical calibration and PVT
