Ethical Dimensions of Pharmaceutical Advertising in Nigeria: Media Practices, Regulatory Oversight, and Implications for Public Health Policy

Abstract

Introduction: Pharmaceutical advertising plays a critical role in shaping medicine use, prescribing behaviour, and public perceptions of health. While ethical promotion can support informed decision-making and rational medicine use, inappropriate or misleading advertising poses significant risks to patient safety and public health, particularly in low- and middle-income countries (LMICs). This narrative review examines the ethical dimensions, media practices, and regulatory oversight of pharmaceutical advertising in Nigeria, with a focus on implications for public health and policy.
Methods: A comprehensive review of peer-reviewed literature, regulatory instruments, policy documents, and grey literature were conducted to synthesise evidence on ethical standards governing pharmaceutical promotion, dominant advertising strategies across traditional and digital media, and the effectiveness of existing regulatory frameworks. International ethical benchmarks, including World Health Organization and International Pharmaceutical Federation guidance, were used to assess Nigerian practices within a global context.
Key Findings/Discussion: The review finds persistent ethical challenges in pharmaceutical advertising in Nigeria, including exaggerated therapeutic claims, inadequate risk disclosure, exploitation of consumer vulnerability, and increasing use of digital and influencer-driven marketing with limited regulatory oversight. Although Nigeria has a multi-agency regulatory architecture involving NAFDAC, the Advertising Regulatory Council of Nigeria, and the Pharmacy Council of Nigeria, institutional overlaps, enforcement gaps, and limited capacity, particularly in digital media monitoring undermine effective governance. These challenges contribute to irrational medicine use, self-medication, antimicrobial misuse, and erosion of public trust.
Conclusion: The review highlights the need for stronger inter-agency coordination, clearer regulatory mandates, enhanced digital surveillance mechanisms, professional training, and public media literacy.
Strengthening ethical pharmaceutical advertising is essential to safeguarding public health, promoting rational medicine use, and advancing medicines governance in Nigeria and comparable LMIC settings.
