Introduction
Pharmacovigilance (PV) plays a critical role in safeguarding public health by monitoring the safety of medicines throughout their lifecycle.
However, in many countries—particularly in resource-limited settings—the growth of effective pharmacovigilance systems is often hindered by limited funding, infrastructure gaps, and insufficient national coordination.
Over time, the activities related to monitoring, assessing, and preventing adverse drug reactions (ADRs) have been formally consolidated under the discipline of pharmacovigilance. Institutions responsible for coordinating these activities at a national level are designated as National Pharmacovigilance Centres (NPCs).
Pharmacovigilance is not an individual responsibility; it requires structured national oversight, regulatory support, and coordinated participation from healthcare professionals, industry, and public health authorities.
National Pharmacovigilance Centres
National Pharmacovigilance Centres (NPCs) are officially designated institutions responsible for coordinating drug safety activities at the national level within a country.
They function as the central hub for collecting, evaluating, and reporting adverse drug reactions (ADRs) and support regulatory decision-making related to the safe use of medicines.
NPCs work closely with international organizations such as the World Health Organization (WHO) and contribute national safety data to global drug-monitoring systems coordinated by the Uppsala Monitoring Centre (UMC).
“National Pharmacovigilance Centres are the backbone of medicine safety systems, transforming individual adverse event reports into national and global public health action.”
Necessity of Pharmacovigilance centres
The necessity of NPCs arises from multiple public health and regulatory challenges:
- Increasing availability and complexity of medicinal products
- Expansion of over-the-counter (OTC) medicines and self-medication practices
- Cost-containment pressures within healthcare systems
- Need for early detection of rare, serious, or unexpected adverse reactions
In most countries, pharmacovigilance systems are integrated within national regulatory authorities for operational and financial governance. This integration ensures that safety data directly informs regulatory actions such as labeling changes, restrictions, or market withdrawal.
Without a functional NPC, countries risk fragmented safety reporting, delayed signal detection, and inadequate protection of patients.
Governance and Regulatory Oversight
National Pharmacovigilance Centres are typically:
- Hosted or overseen by governmental health authorities or drug regulatory agencies
- Affiliated with the WHO Programme for International Drug Monitoring (established in 1968)
- Supported by national legislation or regulatory mandates
WHO emphasizes that a pharmacovigilance system must be backed by a regulatory authority to be effective. Strong collaboration between regulators and NPCs ensures that safety concerns lead to timely and enforceable public health actions.
In some settings, NPCs may also be housed within:
- Academic institutions
- Teaching hospitals
- Departments of clinical pharmacology, pharmacy, toxicology, or epidemiology
Provided that national regulatory linkage is maintained.
Roles and Responsibilities
NPCs are responsible for establishing, maintaining, and strengthening the national pharmacovigilance system. Key functions include:
1. Establishment of the PV System
- Coordinating with health authorities and clinical institutions
- Defining the national pharmacovigilance framework and objectives
2. ADR Data Collection
- Designing and distributing ADR reporting forms
- Collecting reports from healthcare professionals, patients, and MAHs
- Accepting spontaneous (unsolicited) reports from multiple sources
3. Case Assessment and Data Management
- Verification and validation of ADR reports
- Coding and interpretation of adverse reaction information
- Maintenance of national safety databases
4. Capacity Building and Training
- Training pharmacovigilance staff in data collection and case evaluation
- Educating healthcare professionals on ADR reporting requirements
5. Awareness and Communication
- Promoting ADR reporting through hospitals, academia, and professional associations
- Publishing safety information in medical journals and professional platforms
6. National and International Coordination
- Acting as the single national contact point for global pharmacovigilance systems
- Submitting national data to WHO-linked databases such as VigiBase
- Collaborating with international pharmacovigilance institutions
NCPs vs CROs
National Pharmacovigilance Centre (NCP):
Key Characteristics
- Operates under a national regulatory authority
- Focuses on population-level drug safety
- Collects ADRs from all sources nationwide
- Represents the country in global PV systems such as the WHO Programme
Pharmacovigilance CRO / Safety Monitoring Company (CRO):
Key Characteristics
- Works on behalf of Marketing Authorization Holders (MAHs)
- Focuses on product-specific safety obligations
- Operates under contractual agreements
- Does not have regulatory authority
Key takeaways
National Pharmacovigilance Centres are the backbone of national drug safety systems
NPCs ensure systematic collection, evaluation, and reporting of ADRs
Strong linkage with regulatory authorities is essential for effective pharmacovigilance
NPCs contribute national data to global drug safety monitoring efforts
Pharmacovigilance outsourcing companies support MAHs but do not replace NPCs
A functional NPC is critical for protecting public health in an evolving therapeutic landscape
Strengthen drug safety where it matters most.
Support, collaborate with, or advocate for your National Pharmacovigilance Centre to ensure timely detection, assessment, and prevention of adverse drug reactions.
Strong national systems save lives—be part of building a safer healthcare ecosystem today.
Conclusion
Pharmacovigilance remains essential in addressing the challenges posed by the increasing number, complexity, and potency of medicines—each carrying an inherent and sometimes unpredictable risk.
A National Pharmacovigilance Centre plays a vital role in safeguarding public health at the national level, while pharmacovigilance safety monitoring or outsourcing companies assist individual organizations in meeting regulatory obligations. Together, they form a collaborative ecosystem that ensures medicines remain safe, effective, and trustworthy throughout their use.
