Assessment of safety profile of ivabradine in real-world scenario using FDA adverse event reporting system database.

Background: Ivabradine is primarily indicated for patients with sinus rhythm and a heart rate ≥ 75 beats/min, who have NYHA class II-IV chronic heart failure with systolic dysfunction. There is currently a lack of large-scale, real-world studies concerning its drug adverse reactions.

Research Design & Methods: This research assesses the side effects of ivabradine by analyzing reports of adverse events (AEs) from the FDA's Adverse Event Reporting System (FAERS) database. To evaluate the importance of these AEs, four sequential analytic strategies were utilized.

Results: In total, 2,701 ivabradine-related AE reports were identified in the FAERS database. We identified 26 ivabradine-induced AEs, each with more than 20 reports, including some significant AEs not mentioned on the product label. The timing of AEs was also analyzed, with the majority of AEs occurring within the first month of ivabradine use. Gender-specific analysis indicates that female have a higher risk of AEs, such as off-label use, tachycardia, drug effectiveness for unapproved indications, and rash compared to male.

Conclusion: This study provides important information for maximizing the usage of ivabradine, increasing its efficacy, and reducing any possible negative effects. The actual clinical use of the medication will be greatly aided by this knowledge.
