Idiosyncratic drug-induced liver injury (DILI) is a common adverse drug reaction. Amoxicillin-clavulanate is a frequent cause, while azathioprine and infliximab pose the highest risk for liver injury.
Area of Science:
- Pharmacovigilance
- Hepatology
- Drug Safety
Background:
- Idiosyncratic drug-induced liver injury (DILI) is an underreported adverse drug reaction.
- The LiverTox database provides public access to documented drug hepatotoxicity information.
- Analysis reveals a significant percentage of drugs have associated liver injury case reports.
Purpose of the Study:
- To analyze drug-induced liver injury data from the LiverTox database.
- To identify drugs with a high incidence of DILI.
- To assess the risk of DILI associated with specific medications.
Main Methods:
- Critical analysis of drug hepatotoxicity data from LiverTox.
- Review of prospective studies on DILI incidence.
- Identification of commonly implicated agents and high-risk drugs.
Main Results:
- 53% of analyzed drugs had at least one convincing report of liver injury.
- Only 48 drugs had over 50 reported DILI cases.
- Amoxicillin-clavulanate is the most common cause of DILI in prospective studies.
- Azathioprine and infliximab showed the highest risk for DILI in a recent study.
Conclusions:
- Drug-induced liver injury is a significant concern with widespread implications.
- Amoxicillin-clavulanate is a leading cause of DILI, affecting approximately 1 in 2300 users.
- Azathioprine and infliximab represent high-risk medications for DILI.
