is to promote patient safety by monitoring, assessing, and preventing adverse effects and other drug-related problems associated with pharmaceutical products. Here are the key roles and functions of pharmacovigilance:
1. Detection and Reporting: Pharmacovigilance involves the collection and analysis of information on suspected adverse
drug reactions (ADRs) from various sources, including healthcare professionals, patients, regulatory authorities, and clinical trials. This data forms the basis for identifying potential safety concerns and generating safety signals.
2. Assessment and Evaluation: Pharmacovigilance professionals assess the collected data to determine the causality, severity,
and frequency of reported adverse events. This involves evaluating the available evidence and conducting analyses to establish the relationship between the medication and the observed reaction. Pharmacovigilance also aims to identify risk factors, subpopulations
at higher risk, and potential interactions with other drugs.
3. Benefit-Risk Evaluation:

plays a crucial role in evaluating the overall benefit-risk balance of medications. It involves weighing the potential benefits of a drug against its identified risks to ensure that the benefits outweigh the potential harm. This evaluation is essential for
regulatory decision-making, labeling updates, and healthcare professionals' and patients' informed decision-making regarding the use of medications.
4. Signal Detection:
Overview of Pharmacovigilance
professionals use statistical and analytical techniques to detect safety signals, which are indications of previously unrecognized risks or patterns of adverse events associated with a particular drug. Signal detection involves analyzing the collected data
for patterns, trends, and disproportionality of specific adverse events.
5. Communication and Information Dissemination: Pharmacovigilance plays a vital role in communicating safety information
to healthcare professionals, regulatory authorities, Clinical Data Operations Training,
and patients. Timely dissemination of safety alerts, drug safety updates, and risk communications helps healthcare providers make informed decisions about prescribing and managing medications. Patient education and awareness initiatives empower individuals
to report adverse events and actively participate in their own safety.
Overall, pharmacovigilance plays a pivotal role in safeguarding patient health and ensuring the continuous monitoring,
evaluation, and improvement of medication safety throughout their lifecycle.
