The Either-Or Trap: Consequences of Enhanced Mechanical Calibration vs Fully Qualifying your Dissolution Equipment

Lessons from a USP expert: Why fully qualified dissolution instruments matter.

Event Overview

Dissolution and drug release testing are used to demonstrate the consistency of pharmaceutical product performance within and across batches of critical medicines. Learn from a USP expert 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.

By attending this presentation, you will learn about:

  • The rigorous development of the USP Dissolution Performance Verification Standard (DPVS)
  • Potential sources of variability in dissolution testing related to the equipment operation and setup
  • Risks associated with only choosing mechanical calibration or performance verification testing in the qualification of dissolution testing equipment
  • What it means to have a “fully qualified” dissolution instrument according to USP specifications.
