Protocol deviations in medicine quality tests.

Area of Science:

• Pharmaceutical sciences
• Public health
• Regulatory science

Background:

• Pharmacopoeias establish global medicine quality standards and testing protocols.
• Current pharmacopoeial methods are often complex, requiring specialized resources and generating significant waste.
• These standards are applied beyond manufacturing, including post-marketing surveillance in low- and middle-income countries (LMICs).

Purpose of the Study:

• To highlight challenges in applying pharmacopoeial methods in resource-constrained settings.
• To examine the impact of work-arounds on medicine quality testing outcomes.
• To advocate for adapted pharmacopoeial guidance for research and surveillance in LMICs.

Main Methods:

• Review of existing pharmacopoeial standards and their application.
• Case study analysis of modified amoxicillin tablet testing in Indonesia.
• Discussion of the implications of methodological adaptations on study results.

Main Results:

• Work-arounds in pharmacopoeial testing can significantly distort study outcomes.
• Failure to acknowledge or describe modifications leads to potential misinterpretation of medicine quality data.
• Existing methods may not be feasible or appropriate for all research and surveillance contexts.

Conclusions:

• Standard-setting bodies should provide evidence-based guidance for modified, low-cost, and sustainable testing methods in resource-constrained settings.
• Guidance should consider contexts where immediate patient safety is not the primary risk.
• The research community must report methodological modifications and their outcomes to inform best practices.
