Why Dissolution Testing is the Lifeline of Drug Registration

Introduction

For oral formulations like films, sustained-release tablets, and controlled-release granules, dissolution testing is a critical parameter that reflects drug release performance. It not only determines onset speed and dose stability but also forms a core part of required registration documentation. Inaccurate or non-compliant dissolution testing can severely delay or derail regulatory approvals.

1. Why Is Dissolution Testing So Important?

• Mandatory for regulatory approval: Most authorities require detailed dissolution profiles as part of consistency evaluation.
• Guides formulation optimization: Comparing dissolution curves helps fine-tune drug release rates.
• Ensures batch-to-batch consistency: Prevents therapeutic variation caused by manufacturing deviations.

2. Common Pitfalls in Dissolution Tester Selection

• Mistaking simple stirring for compliant dissolution testing.
• Poor temperature control and sampling timing introduce variability.
• Inadequate sampling intervals that miss critical points in the release profile.
• Lack of proper software for data visualization and curve analysis.

3. Industry Trends

• Multi-channel parallel testing: Enables higher throughput and multiple sample points.
• Automation and cleaning integration: Enhances repeatability and reduces human error.
• Global pharmacopeia alignment: USP, EP, ChP increasingly enforce data integrity and reproducibility.
