Abstract:
Objective To explore and analyse the signals of adverse events of esketamine,and to provide references for rational clinical use of the drug.Methods The adverse event reports of esketamine from the first quarter of 2019 to the fourth quarter of 2023 in the U.S.Food and Drug Administration Adverse Event Reporting System(FAERS)database were collected.The reporting odds ratio(ROR)method and information component(IC)method in the disproportionality analysis and random forest(RF)algorithm,K-nearest neighbor algorithm and extreme gradient boosting(XGBoost)algorithm in machine learning algorithms were used for signal mining of target medicines respectively.The accuracy of machine learning signal detection results was assessed by the area under the curve(AUC).Results A total of 5 247 adverse event records with esketamine as the primary suspect drug were obtained.Using the traditional detection measures of dis-proportionality,138 positive signal results were detected,6 new adverse events including anticholinergic syndrome,urinary incontinence,double vision,pyelonephritis,spontaneous pneumothorax,biliary obstruction,were not included in the FDA drug inserts,and it was found that the drug may be more likely to cause cardiovascular problems.The results of the machine learning training showed that XGBoost algorithm and RF algorithm performed moderately well,with AUC means of 0.928 and 0.921,respectively.A total of 4 new potential adverse drug event signals,diplopia,deterioration of general physical health,suicidal ideation and withdrawal syndrome were detected by XGBoost algorithm and RF algorithm.Conclusion Esketamine is accompanied by some unknown risks while obtaining significant efficacy and adverse events not mentioned in the specification may occur in clinical practice.Healthcare professionals should be fully alert to the relevant adverse events when applying them in clinical treatment and take timely measures to ensure the safety of the treatment.
