ReviewRanolazine for the prevention or treatment of atrial fibrillation: a systematic review.
The use of currently available antiarrhythmic drugs for atrial fibrillation is limited by their moderate efficacy and the considerable proarrhythmic risk. Ranolazine, an antianginal agent, has been reported to possess antiarrhythmic properties, resulting in a reduction of supraventricular and ventricular arrhythmias. We performed a systematic review of the clinical studies reporting the outcome of patients treated with ranolazine for the prevention or treatment of atrial fibrillation in various clinical settings. ⋯ No meta-analysis could be performed because for most of the clinical scenarios, there was only one study investigating the effect of ranolazine. Except for one large randomized trial, all the other studies were either relatively small randomized studies or retrospective cohort analyses, which in several cases lacked a control group. This systematic review indicates a modest beneficial effect of ranolazine administered for the prevention or treatment of atrial fibrillation across several clinical settings without substantial proarrhythmic risk.
