The Pharmacovigilance Lifecycle: From Lab Bench to Bedside
In the pharmaceutical world, a drug’s journey doesn’t end when it hits the pharmacy shelf. In fact, for Pharmacovigilance (PV) experts , that is where the most critical work begins. The Pharmacovigilance lifecycle is a continuous, circular process designed to monitor a medicine’s safety profile from its earliest clinical trials until the day it is discontinued. Here is a breakdown of the stages that keep patients safe worldwide. Phase 1: Pre-Marketing (The Clinical Trial Phase) Before a drug is available to the public, it undergoes rigorous testing. In this stage, PV is focused on safety data collection from controlled environments. The Goal: Identify common side effects and establish a "baseline" safety profile. Key Activity: Serious Adverse Events (SAEs) must be reported to regulators within strict timelines (often 7 to 15 days). Phase 2: Signal Detection (The "Listening" Phase) Once the drug is approved and used by thousands (or millions) of people, PV enter...
