DAR
A log of study drugs kept by an investigator running a clinical trial. It lists many things about each drug, including the drug name, lot number, expiration date, the amount of drug received, used, returned, or thrown away, and the amount left. DARs help make sure that a clinical trial is done safely and correctly. DARs are required by the U.S. Food and Drug Administration (FDA). Also called Drug Accountability Record.
