Pharmacovigilance today involves a comprehensive suite of activities aimed at ensuring the safe use of drugs, vaccines, and medical products. It all begins with rigorous clinical trials that identify safe dosages and assess the efficacy of medications. These trials are meticulously structured in phases, starting with small-scale studies to determine safe dose levels, and gradually expanding to evaluate the treatment’s efficacy and potential side effects in larger populations. Each phase serves a distinct purpose, from assessing drug safety and side effects in the initial stages to evaluating comparative efficacy and longer-term impact in later stages. This multi-phase approach ensures a thorough vetting process before any drug reaches the market.
The successful completion of these clinical trials culminates in regulatory approval from the FDA, marking a significant milestone for the drug. However, pharmacovigilance does not cease with this approval; it transitions into an ongoing phase of post-market surveillance. This continuous process involves the diligent collection and analysis of data related to the drug’s performance in everyday use. The goal is to identify any new adverse effects or safety concerns that might not have been evident in controlled clinical trial settings. Through comprehensive tracking and monitoring, pharmacovigilance aims to mitigate risks and enhance the overall safety profile of medications over their lifecycle in the market.
