Safety of oral propafenone in the conversion of recent onset atrial fibrillation to sinus rhythm: a prospective parallel placebo-controlled multicentre study

AIM: Oral propafenone is effective in restoring sinus rhythm however the proarrhythmic effects are still unknown. The Safety Antiarrhythmic Therapy Evaluation (SATE) trial was a prospective randomized placebo-controlled multicentre study which evaluated the safety of acute oral loading dose of propafenone in patients with recent onset atrial fibrillation. Secondary end-points were to evaluate the effect of digitalis added to propafenone in ventricular rate control and the efficacy of propafenone alone or added to digitalis compared with efficacy of digitalis plus quinidine. METHODS AND RESULTS: 246 patients (126 male; 58+/-11 years) with atrial fibrillation of <48 h duration were randomly allocated to one of four groups: digitalis 0.75-1 mg i.v. plus quinidine 1100 mg (D+Q, 70 patients); propafenone 450-600 mg orally (PNF, 66 patients); propafenone 450-600 mg orally plus digitalis 0.750-1 mg i.v. (PNF+D, 70 patients); placebo (Pl, 40 patients). All patients underwent 24-h ECG Holter monitoring. Safety was assessed by evaluating the appearance of adverse events classified as mild, moderate and severe. No severe adverse events were reported. Short lasting asymptomatic atrial flutter episodes with atrio-ventricular conduction > or =2:1 were observed in 14% of the D+Q group, 21% PNF, 18% PNF+D and in 8% Pl. One patient in the D+Q group and four in the PNF+D group showed asymptomatic runs of 3-4 ventricular ectopic beats. Reversible sinus atrial blocks (<3 s) were detected in two patients of the D+Q group and in two of the PNF group. In patients with persistent atrial fibrillation the ventricular rate was similar in the four study groups. At 3 h the high efficacy of propafenone was confirmed. At the 24th hour no differences were found between active treatment and placebo arms. CONCLUSION: Propafenone in a single oral loading dose is safe and promptly effective in patients with recent onset atrial fibrillation.

Long term efficacy of propafenone for prevention of atrial fibrillation.

OBJECTIVE: Propafenone, a class IC antiarrhythmic drug, has been successful in the treatment of ventricular and supraventricular arrhythmias. This study retrospectively evaluated the efficacy of propafenone in the prevention of recurrent atrial fibrillation. DESIGN: Propafenone was given to 81 patients (49 males and 32 females, mean age 61 +/- 16 years) with recurrent atrial fibrillation. The mean dose of propafenone was 701 +/- 235 mg. Patients were monitored for recurrent arrhythmias. MAIN RESULTS: Long term follow-up over 30 +/- 1.7 months showed 31 patients (38%) remained on propafenone with complete or partial control of atrial fibrillation. The drug was stopped in 35 due to inefficacy, in 12 due to adverse effects, and in three due to desire for ablation therapy. CONCLUSION: Propafenone may be effective in some patients for long term prevention of atrial fibrillation, although efficacy may decrease over time.

Efficacy of intravenous and per os propafenone in the ambulatory treatment of recent-onset atrial fibrillation]

Propafenone efficacy in conversion of atrial fibrillation to sinus rhythm has been well documented. In this study we considered propafenone efficacy according to a graduated protocol of administration. Forty-two patients with recent-onset atrial fibrillation, without left ventricular failure, ischemic symptoms and in absence of antiarrhythmical treatment, were treated according to the following protocol: propafenone 1 mg/kg i.v. (5 min) followed, in the non-responder patient group, by a second dose, 0.5 mg/kg i.v. (15 min). Patients with persistent atrial fibrillation received 900 mg/daily of propafenone per os, at home for two days. Thereafter, patients still not restored to sinus rhythm were considered non-responders. Patients who were converted to sinus rhythm received 450 mg daily of the drug (oral administration), at home, as antiarrhythmical prophylaxis, for three months. Thirty-nine patients were converted to sinus rhythm (92.8%), 24 of them after intravenous propafenone (57.2%), and the other 15 (35.6%) after oral administration of the drug. The average heart rate in patients not converted to sinus rhythm with intravenous propafenone was significantly reduced after drug administration, compared to basal values (from 136.4 +/- 18.1 to 107.1 +/- 17.6, p < 0.01), allowing home treatment. No major cardiac effects were observed after infusion, nor after oral administration of propafenone. During a three-month follow-up we observed 3 cases of relapsed atrial fibrillation and 2 discontinued treatments due to minor gastroenteric side effects. In conclusion, propafenone therapy in ambulatory regimen is safe and effective in patients with recent-onset atrial fibrillation. In many patients refractory to IV treatment, further therapeutic success may be achieved following oral propafenone administration.     

Pharmacological cardioversion with intravenous propafenone in atrial fibrillation

The efficacy and safety of intravenous propafenone for conversion of recent-onset and chronic atrial fibrillation was assessed in 46 patients. 40 with atrial fibrillation associated with or without structural heart disease (mean age 63 +/- 14 years) and 6 patients with atrial fibrillation related to the Wolff-Parkinson-White syndrome (mean age 34.8 +/- 13 years). Propafenone treatment was administered at 2 mg/kg over 15 minutes under continuous electrocardiographic monitoring. In 28 of 32 (87.5%) patients with paroxysmal and/or recent-onset atrial fibrillation a stable sinus rhythm was restored within 1 hour after propafenone (mean 17 +/- 11 minutes) and in only 3 of 8 (37.5%) with chronic atrial fibrillation (p < 0.05). Conversion to sinus rhythm was obtained in 5 of 6 (83.3%) patients with atrial fibrillation related ventricular preexcitation, mean time 21 +/- 12 minutes. Propafenone had an additional effect reducing mean heart rate (141 +/- 21 to 102 +/- 15 beat per minute, p < 0.05) and the shortest preexcited R-R intervals was increased, mean 231.6 +/- 27.8 to 355 +/- 37.2 milliseconds (p < 0.001) in cases associated with ventricular preexcitation. Dizziness, hypotension and transient conduction disturbances occurred in only one patient with rheumatic valvular heart disease: EF 40%. Propafenone is an effective and safe antiarrhythmic drug for converting paroxysmal and/or recent-onset atrial fibrillation of various origins with a more limited efficacy in chronic atrial fibrillation.     

Propafenone: A New Anti arrhythmic for Treatment of Chronic Ventricular Arrhythmias

Propafenone is a new anti arrhythmic agent with primarily membrane-stabilizing action. Three U.S. controlled double-blind cross-over studies demonstrated the efficacy of propafenone in suppressing ventricular premature complexes (VPCs), including repetitive forms: 67–83% of patients had greater than 80% reduction of VPCs, 62% achieved greater than 90% reduction of couplets and 80%–100% achieved 200% abolition of ventricular tachycardia runs. Other studies showed that propafenone is effective in controlling ventricular arrhythmias refractory to conventional anti arrhythmic agents. Propafenone is at least as effective as these agents. Long-term sustained efficacy of propafenone was shown in some preliminary studies. Because of the variation in individual response to the drug, therapy should be individualized for each patient. Propafenone is well tolerated: side effects of propafenone are few and involve mostly the cardiac conduction system. Propafenone would be a significant addition to the anti arrhythmic armamentarium.
