Real-world safety of Lacosamide: A pharmacovigilance study based on spontaneous reports in the FDA adverse event reporting system

Abstract

IntroductionLacosamide is licensed for the treatment of focal seizures in both adults and children, however there is little information available on its adverse reactions. Using the FDA Adverse Event Reporting System (FAERS), we seek to assess adverse occurrences that may be related to Lacosamide. MethodsOn the basis of the FAERS database from the fourth quarter of 2008 to the second quarter of 2022, disproportionality analysis was carried out using the reporting odds ratio (ROR) method, the United Kingdom Medicines and Healthcare Products Regulatory Agency omnbius standard (MHRA) method, and the bayesian confidence propagation neural network (BCPNN) method. We extracted valuable positive signals for designated medical event (DME) screening, focused on the evaluation and comparison of safety signals appearing in DME with system organ classification (SOC) analysis. ResultsA total of 10,226 adverse reaction reports with Lacosamide as the primary suspect drug were obtained, with 30,960 reported cases, detecting 232 valuable positive signals, involving a total of 20 SOCs, of which the most frequently reported SOCs were nervous system disorders (6537 cases, 55.21%), psychiatric disorders (1530 cases, 12.92%), injury poisoning and procedural complications (1059 cases, 8.94%). According to 232 valuable positive signals with DME screening results, two signals of stevens-johnson syndrome and ventricular fibrillation were consistent with PT signals on the DME list, with the two SOCs focusing on skin and subcutaneous tissue disorders and cardiac disorders, respectively. ConclusionsOur research demonstrates that the clinical use of Lacosamide should be noticed and avoided in relation to ADRs since it raises the risk of cardiac arrest, ventricular fibrillation, stevens-johnson syndrome, and rhabdomyolysis.
