Why Content Uniformity Testing Is a Critical Regulatory Line — Especially for ODFs and Tablets

Why Content Uniformity Testing Is a Critical Regulatory Line — Especially for ODFs and Tablets

Introduction
Whether you're producing pharmaceuticals or nutraceuticals, content uniformity is one of the most scrutinized aspects in product registration. For modern dosage forms like oral films (ODFs), multilayer tablets, or combination products, even the smallest deviation in active ingredient (API) distribution can lead to batch rejection. Manual methods are no longer enough to meet global demands for data integrity and traceability.

Challenges Faced by Manufacturers

  • General-purpose lab equipment heavily relies on manual operations
  • Lack of automated sampling or pre-treatment processes
  • Poor repeatability, easily questioned during on-site inspections
  • No structured data or statistical analysis tools for audit compliance

What a Compliant Uniformity Test Setup Should Include

  • Automated modules for sample crushing, extraction, and division
  • Direct integration with HPLC or UV spectrophotometers for automated quantification
  • End-to-end data traceability, including batch number tracking and parameter logging
  • Statistical tools to generate mean, standard deviation, %RSD, and outlier ratios

HUANGHAI’s Integrated Solution

  • Pre-treatment stations paired with content analyzers for end-to-end testing
  • Automated data capture and registration-ready report exports
  • Traceability enabled through linkage with HUANGHAI’s ODF coating systems
