Recent drug withdrawals and cases of adverse drug effects on patients have stolen the confidence among people in using certain drugs. The only way to instill confidence in patients is to make the promise of safety and adherence to quality standards in available medicines. Here marketing doesn't work. Only honesty does. And pharmacovigilance signal detection is one of the best ways to detect and prevent adverse events.

Let's face it; drug safety is an issue because no one is fully aware of what side effects it can have. So it is important to detect an adverse event with the assistance signal detections.The practice of pharmacovigilance allows detection, assessment, understanding and prevention of adverse effects or any other possible drug-related problems. It is carried out by pharmaceutical companies on their products and by government agencies on all medicinal products.

The signals are detected on the basis of spontaneous reporting of adverse cases. These cases are carefully studied and categorized into a database. A pattern is established through a scientific method of computation based on data tables. This gives a fair idea of the potential signals that lead to adverse events

Having detected the potential signals, a validation of whether or not they are signals is made since they are cases when signals occur due to a disease and not really from a dug. Following this, a review of the drug is made to consider its potential risks and benefits, on the basis of which its marketing authorization is revoked or suspended.

This method of detection is a god way to assess the merits of individual drugs since it does not bank upon a single adverse events, but takes into consideration several similar events. In addition to ensuring drug safety, this method also helps detect signals for subsequent adverse events.
