The Cardiac Sodium Channel Safety Profile of Cenobamate at Therapeutic Concentrations: In Vitro Analyses.
Article in Clinical and translational science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The US Food and Drug Administration (FDA) issued a Drug Safety Communication for the antiseizure drug lamotrigine (Lamictal), warning of the risk of QRS prolongation and cardiac arrhythmias. The FDA also requested that other antiseizure medications with a similar mechanism of action (e.g., block of neuronal sodium channels), including cenobamate, be evaluated for their risk as a cardiac sodium channel blocker. The purpose of this in vitro study was to determine the cardiac sodium channel blocking effects of cenobamate and its sodium channel classification. Follow-up experiments were also performed with cenobamate at its highest free therapeutic concentration (66 μM). Experiments were performed using the manual patch clamp technique at physiologic temperatures. Despite its classification as a Class Ib and Id antiarrhythmic, cenobamate was found to have little effect on the cardiac sodium channel when tested in vitro at therapeutic levels. These findings provide further clarity and support for the clinical safety of cenobamate in patients without cardiovascular risk factors.
