Abstract: Objective To provide reference for safe and rational use of sofosbuvir/velpatasvir(SOF/VEL) and ledipasvir/sofosbuvi(LED/SOF) by analyzing signals of post-marketing adverse drug reactions (ADR) of the two drugs. Methods Data on adverse events reported by the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) between January 1, 2017 and September 30, 2021 was mined by adopting the reporting odds ratio (ROR) method and the information component (IC) method. Description terms of ADR in the reports were standardized using the medical dictionory for regulatory activities(MedDRA) terminology. ADR with signals were screened out and compared. Results A total of 16 signals of SOF/VEL and 18 signals of LED/SOF were finally obtained, including 7 overlapping signals which mainly involved systemic, gastrointestinal, hepatobiliary, neurological and mental system damage, and the risk of HBV reactivation. The specific ADR of SOF/VEL were increased appetite, alcohol use and heavy menstrual bleeding while those of LED/SOF were nonacute porphyria, cholangiocarcinoma and cryoglobulinaemia. Conclusion In this study, ROR and IC methods have been used to dig out the ADR risk signals of SOF/VEL and LED/SOF, which provides new evidence for their safe and rational use.
