AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
IMURAN (azathioprine) is an oral purine antimetabolite that inhibits nucleic acid synthesis, making it effective as an immunosuppressant. It is used primarily off-label for autoimmune conditions, inflammatory bowel disease, and transplant rejection prevention. The drug has been in clinical use since 1968 and remains a foundational therapy despite high off-label utilization rates.
