Background: Interleukin-23 (IL-23) inhibitors are widely used in clinical practice for Psoriasis , but multiple adverse events (AEs) have been reported. We aimed to describe the distribution of AEs related IL-23 inhibitors including Guselkumab, Tildrakizumab, Risankizumab, Ustekinumab. Methods: Data from January 1, 2014, to September 30, 2022 were extracted from the FDA Adverse Event Reporting System (FAERS). Disproportionality analysis including reporting odds ratio (ROR) and information component (IC) was performed to access potential signals. It was defined a signal when the lower limit of 95% confidence interval (CI) of ROR (ROR025) more than one or IC(IC025) exceeding zero, with the number of cases greater than or equal to three at the same time. Results: A total of 41,408,408 drug-AE reports were extracted from the FAERS database involving 13271168 people. 704, 13164, 62853, 11399 patients have used Tildrakizumab, Guselkumab, Ustekinumab, Risankizumab and 8, 20, 107 and 115 signals were found respectively. The “infections and infestations” has the highest incidence of SOC in Tildrakizumab(6/8), Guselkumab(5/20), Ustekinumab(50/107), Risankizumab(25/115). Conclusion: Our pharmacovigilance analysis showed that a high frequency was reported for AEs triggered by IL-23 inhibitors. IL-23 inhibitors had the potential to impair immune function resulting in a risk of infections or cancers. We need to pay special attention to Risankizumab because the drug has more AE occurrences than Ustekinumab despite Risankizumab has few reports than Ustekinumab and launched later than Ustekinumab.
