Hypothesis

The study investigates how risks associated with transporter-mediated drug-drug interactions are reported in medicinal product information.

Conclusion

There is potential for improving the clarity and relevance of warnings in product information regarding transporter-mediated drug-drug interactions.

Supporting Evidence

  • 192 out of 859 approved medicinal products had relevant SmPC text.
  • Most texts were located in SmPC Section 5.2.
  • BCRP had the highest number of clinically relevant interaction texts.

Takeaway

This study looked at how warnings about drug interactions are written in medicine guides, finding ways to make them clearer and more useful for doctors.

Methodology

The study screened the Summary of Product Characteristics (SmPCs) of medicinal products approved in the EU from 2012 to 2023 for warnings on specific transporters and categorized the warnings based on clinical relevance.

Limitations

The study only included products approved through the central procedure and may not represent all medicinal products.
