Assessing the ARIA System's Ability to Evaluate a Safety Concern

The Food and Drug Administration (FDA) uses the Active Risk Identification and Analysis (ARIA) System to monitor the safety of medications. During the drug approval process, potential safety concerns are sometimes found that require further study after FDA approval. Before requiring the drug's manufacturer to conduct a post-approval safety study, FDA must determine whether it is feasible to answer the safety question in ARIA. FDA describes the reasons why a safety concern could or could not be evaluated in ARIA in the documents linked below.
