Drug evaluation is a process of assessing the safety, efficacy, and effectiveness of pharmaceutical drugs before they are approved for clinical use. This involves testing the drug in laboratory settings, animal models, and clinical trials to determine its potential benefits and risks for patients. Drug evaluation also involves monitoring the drug's performance in real-world settings after it has been approved for commercial use. This research area is crucial for ensuring that safe and effective medications are available to patients and for providing healthcare professionals with the information they need to make informed treatment decisions.
