OBJECTIVE To mine and analyze the risk signal of glucagon- like peptide -1 receptor agonists （GLP-1RA）related adverse drug reaction （ADR）. METHODS ADR data related to GLP- 1RA from April 1，2005 to October 16，2021 in the openFDA database were collected ，and the Bayesian confidence propagation neoral network （BCPNN）method was used for data mining. ADR were classified and described by using systematic organ classification （SOC）of drug ADR terminology set in 24.0 edition of MedDRA. RESULTS & CONCLUSIONS A total of 175 719 ADR reports related to GLP- 1RA were retrieved ，with 140 ADR positive signals ，involving five drugs such as exenatide （77 027 cases of ADR and 31 ADR positive signals ），dulaglutide （45 329 cases of ADR and 26 ADR positive signals ），liraglutide （42 748 cases of ADR and 32 ADR positive signals ）， semaglutide（8 844 cases of ADR and 27 ADR positive signals ）and lixisenatide （1 771 cases of ADR and 24 ADR positive signals）. According to SOC classification ，GLP-1RA-induced ADR involved gastrointestinal system ，hepatobiliary system ，nervous system，urinary and renal system ，endocrine system ，immune system and administration site. In the gastrointestinal system ，the risk of （acute）pancreatitis was higher ，and the order of risk was liraglutide ＞exenatide＞semaglutide＞dulaglutide＞lixisenatide； ADR signal of hepatobiliary system was stronger for cholelithiasis ，and the order of risk was liraglutide ＞semaglutide＞exenatide＞ lixisenatide＞dulaglutide. In the nervous system ，the risk of taste disorder was higher ；compared with dulaglutide and lixisenatide ， liraglutide，exenatide and semaglutide were more likely to cause headache and dizziness. In urinary and renal system ， compared with exena tide，dulaglutide and lixisenatide ，liraglutide and semaglutide were more likely to cause acute renal injury. In the endocrine system ，the risk of hypoglycemia was higher ，and the order of risk was exenatide ＞liraglutide＞lixisenatide＞ semaglutide＞dulaglutide. In the immune system ，lixisenatide was more likely to develop urticaria than other drugs ，dulaglutide and liraglutide did not caused ADR signal. Among the administration sites ，the risk of ADR caused by exenatide and dulaglutide was higher，while the risk of related ADR caused by semaglutide was lower. When using GLP- 1RA clinically ，we should closely monitor the renal function and blood glucose of patients ，and pay attention to patients with sudden upper abdominal pain ；in case of relevant ADR ，timely intervention measures should be taken to ensure the safety and effectiveness of medication.
