Summary

Reporting therapeutic ineffectiveness via adverse drug reaction systems can identify drug defects. However, robust manufacturing and quality control are key to preventing these issues and misuse of reporting systems.

Area of Science:

  • Pharmacovigilance
  • Pharmaceutical Quality Control

Background:

  • Spontaneous reporting systems for adverse drug reactions (ADRs) are crucial for drug safety monitoring.
  • The concept of reporting therapeutic ineffectiveness within ADR systems has been explored.
  • Therapeutic ineffectiveness encompasses various issues including drug interactions, resistance, tolerance, tachyphylaxis, and pharmaceutical defects.

Purpose of the Study:

  • To evaluate the role of reporting therapeutic ineffectiveness in identifying pharmaceutical defects.
  • To discuss the appropriate use of ADR spontaneous reporting systems.

Main Methods:

  • Analysis of the definitions and scope of therapeutic ineffectiveness within established terminologies like WHO-ART and MedDRA.
  • Discussion of the implications of reporting therapeutic ineffectiveness.

Main Results:

  • Reporting therapeutic ineffectiveness can, under specific conditions, aid in detecting pharmaceutical defects.
  • The study highlights potential misuse of ADR reporting, particularly concerning generic substitution.

Conclusions:

  • While reporting therapeutic ineffectiveness may identify some pharmaceutical defects, it is not the primary or most effective method.
  • Implementing strong good manufacturing practices (GMP) and quality control is the most effective strategy to prevent pharmaceutical defects and avoid misuse of ADR reporting systems.
