The Effects of Flecainide Acetate on Inflammatory-Immune Response in Lipopolysaccharide-Stimulated Neutrophils and on Mortality in Septic Rats.

Background: Flecainide acetate is a drug used primarily for cardiac arrhythmia. Some studies also imply that flecainide acetate has the potential to regulate inflammatory-immune responses; however, its mechanism of action is contended. We determined the effects of flecainide acetate on lipopolysaccharide (LPS)-stimulated human neutrophils in vitro and on mortality in a septic rat model.
