ReviewVernakalant--a promising therapy for conversion of recent-onset atrial fibrillation.
This paper reviews the pharmacology, electrophysiology, efficacy and safety of intravenous and oral vernakalant hydrochloride (RSD-1235), a novel antiarrhythmic drug that has relative atrial selectivity by blocking potassium channels that are present in the atria and not the ventricle. In addition, this drug has important rate-dependent sodium channel blocking properties. ⋯ Intravenous vernakalant has the potential to be an important agent in the conversion of atrial fibrillation and oral vernakalant may be a useful drug for the suppression of atrial fibrillation recurrences.
