Global perspective of the risks of falsified and counterfeit medicines: A critical review of the literature

Abstract

Background

The increasing prevalence of falsified and counterfeit medicines globally poses risks to international travellers. This narrative literature review examines the global challenge of falsified and counterfeit medicines, with a specific focus on risks for travellers. The aim is to provide a comprehensive understanding of this multidimensional issue, exploring potential solutions for effective intervention.

Methods

A comprehensive search of databases, including PubMed, MEDLINE, and Scopus, as well as relevant reports from international organisations, was undertaken. There was a focus on extracting information pertaining to the prevalence, types, and geographical patterns of falsified and counterfeit medicines encountered by international travellers. Synthesising this information helped to identify overarching trends and patterns. This narrative review utilised a thematic analysis approach to synthesise the findings.

Results

The findings revealed a diverse range of counterfeit drug categories, spanning from antibiotics to lifestyle medications, posing unique risks to travellers navigating the global pharmaceutical landscape. The review emphasises the geographical distribution of these drugs, with varying consequences for both high- and low-income nations. The inadequate formulations and inconsistent drug release arising from these practices pose severe threats to public health, especially for individuals travelling abroad. The review also highlights the significance of international collaboration in addressing this global challenge, as pharmaceutical supply chains seamlessly cross borders, necessitating a collaborative approach for effective regulation and enforcement.

Conclusions

This review underscores the need for targeted research, collaborative interventions, and technological innovations to address the complexities associated with falsified and counterfeit medicines, ensuring the safety and well-being of international travellers.
