Safety Profile of Statins for Post-Marketing Adverse Cardiovascular Events: A Real-World Pharmacovigilance Analysis.

AIMS AND

objectivesThe purpose of this study was to comprehensively evaluate the association of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) with neurological adverse events using the US Food and Drug Administration Adverse Event Reporting System (FAERS) database, with the aim of guiding the rational use of statins.

methodsThe number and clinical characteristics of adverse events (AEs) to statins in the FAERS database between 2012 and March, 2023, were extracted. Neurological AEs were defined by the system organ classes (SOCs) of "Nervous System Disorders (10029205)" and the corresponding PT. Disproportionality was calculated using the reporting dominance ratio (ROR), proportional reporting ratio (PRR), and information component (IC

resultsBetween January, 2012 and March, 2023, a total of 90,357 AEs were reported for the three statins (atorvastatin, resuvastatin, and simvastatin). The majority of reports on AEs came from the United States (n = 7284). A total of 8409 reports described neurological AEs following the use of the three statins, with atorvastatin accounting for more than half of the reports (n = 4430). The mean age of patients who developed neurological AEs was 55 years and older. The prevalence was similar in female patients (2230/4480) and male patients (1999/4480). Disproportionate analyses showed that at the SOC level, only the correlation between atorvastatin and neurological AEs suggested a positive signal (ROR: 9.77 (9.56-9.99); IC

conclusionThis study suggests that atorvastatin may be associated with an increased risk of neurological AEs. This study provides realistic evidence of the potential risk of statin-related adverse events.
