The Internet and drug safety: what are the implications for pharmacovigilance?

Abstract

Use of the Internet is becoming widespread throughout the world. Its use in the domain of drug safety and pharmacovigilance is spreading rapidly. Governments and industry have taken the lead in developing extensive web sites. The US Food and Drug Administration (FDA), the European Agency for the Evaluation of Medicinal Products (EMEA) and other agencies have developed sites containing enormous amounts of information both on pharmacovigilance in general and on specific drugs in particular. Under the US 'Freedom of Information Act' the FDA has put major parts of its adverse event database on line. Regulatory documents are also available from the FDA site or from hyperlinks described in the site. The US Center for Drug Evaluation and Research updates its site most days and maintains a free automated e-mail announcement service of these updates. Similarly, the EMEA updates its site frequently and publishes extensive material including regulatory documents, guidelines, European Public Assessment Reports on newly approved medications and other useful information. A free update service by e-mail is also available. Although English is the primary language used on the EMEA site, some of the information is available in other languages. Pharmaceutical companies are not using the Internet for pharmacovigilance yet. Rather, the Internet is being used for promotion of their products and for informing consumers on general information on diseases, for financial and investor data and for employment opportunities, etc. Other organisations such as lobbies, consumer groups and medical journals are also beginning to use the Internet. The electronic transmission of safety information, using the standards developed by the International Conference on Harmonization, is currently being tested for the transmission of individual patient adverse event information between companies and governments. In addition, the FDA has begun to accept adverse events from healthcare providers and consumers directly on line using an electronic version of its MedWatch form. It is expected that these developments will change the nature of the way pharmacovigilance is carried out. Significant issues will arise from this including privacy concerns. The European Union's 1995 directive on 'the protection of individuals with regard to the processing of personal data and on the free movement of such data (95/46/EC)' went into effect in October 1998. The enabling legislation now being passed by the member states will produce significant changes in the way companies and governments handle individual patient data in order to assure the privacy and protection of individuals.
