Pharmacovigilance and Drug Safety

Archive for the ‘risk management’ Category

The role of this site is to provide information on how drugs are developed and the role of pharmacovigilance in ensuring drug safety throughout the lifecycle of pharmaceutical products. We cover several different topics and, should you wish to investigate further, maintain links to some of the top experts and specialists in the field of pharmacovigilance. Our expert panel includes individuals with both industry and regulatory experience. We have access to people who have helped to define and shape the science of drug safety into what it is  today and are working on what pharmacovigilance will become in the future.

Many people believe the pharmaceutical industry to be a shady cartel developing poisonous concoctions with no control from governments or the scientific community. The Pharmacovigilance Information Service is here to share information about drug safety and to explain some of the steps that pharmaceutical companies are required to take in order to get their products to market and to keep them there. It also explains the safety roles that the regulatory bodies expect the pharmaceutical companies to fulfill.

DEVELOPMENT OF MEDICINES AND PHARMACOVIGILANCE IN THE EUROPEAN UNION: a guide for the perplexed

This review is intended as a brief introduction to understanding the complex environment in which medicines are developed and their safety monitored. Much of it is applicable generally, but the focus is on the situation in the UK and the European Union.

A major change in the approach to drug safety surveillance after marketing has been introduced in the last 5 years in the EU in the form of risk management planning. This has been incorporated into EU law and is extensively covered by guidelines in Volume 9A. There has been a similar initiative by the US FDA.

For the EU, it is mandatory for companies to submit a Risk Management Plan in accordance with a detailed template and guideline at the time of application for a Marketing Authorisation for most products. Plans also have to be submitted if new safety concerns are identified for a marketed product and all plans must be updated as circumstances change.

Thus companies are required to specify at the time of first marketing areas of safety about which they are currently uncertain and how they will resolve this uncertainty. They must also indicate what measures they will take to reduce known risks and how they will test whether these measures work.

The EU Risk Management Plan (EU-RMP) has 3 main elements. First, a detailed consideration of what is known about the safety of the product, based on pre-clinical and clinical studies. This “safety specification” considers identified risks and potential risks – the latter being areas of uncertainty regarding safety. It also specifies what the limitations of the clinical research program are and what important information about safety is currently missing. In the second component, the “pharmacovigilance plan”, the company must indicate how it proposes to resolve the uncertainties – what extra studies it will carry out after marketing to fill the important gaps in knowledge. The third component is the “risk minimization plan”. This states how the company proposes to reduce the severity or frequency of known adverse reactions. This may involve special communication programs, or educational exercises, or perhaps registration programs for patients, doctors or pharmacists, or other measures. The pharmacovigilance plan and risk minimization plan must include timelines for setting up the programs and milestones for their evaluation.
