Optic neuropathy and optic neuritis, sometimes progressing to total blindness, have been described in a small number of patients treated with amiodarone. Studies on the use of amiodarone for the primary prevention of sudden death in high-risk patients have had mixed results. The initial infusion rate should not exceed 30 mg/min. Abstract The use of amiodarone for postoperative atrial fibrillation (AF) is widespread; however, there is a paucity of data on the optimal duration of overlap when transitioning from intravenous (IV) to oral amiodarone.

Mechanisms of Action In clinical trials, after 48 hours of continued infusions (125, 500, or 1000 mg/day) plus supplemental (150 mg) infusions (for recurrent arrhythmias), amiodarone mean serum concentrations between 0.7 to 1.4 mg/L were observed (n=260). Because a typical oral amiodarone loading dose for ventricular arrhythmia starts with 800-1600 mg/day and for atrial fibrillation starts with 600-800 mg/day, I would assume that for one reason or another a decision was made not to load this patient. Bradycardia should be treated by slowing the infusion rate or discontinuing amiodarone. When the maintenance dose is given IV, the onset and peak will occur earlier, however the duration of action is the same. HHS Vulnerability Disclosure, Help Amiodarone is more effective than sotalol or propafenone in preventing recurrent atrial fibrillation in patients for whom a rhythm-control strategy is chosen. The time at which a previously controlled life-threatening arrhythmia will recur after discontinuation or dose adjustment is unpredictable, ranging from weeks to months.

Peak serum concentrations after single 5 mg/kg 15-minute intravenous infusions in healthy subjects range between 5 and 41 mg/L. Bradycardia and heart block occur in 1 to 3 percent of patients receiving amiodarone.2 Amiodarone-induced proarrhythmia occurs at an annual rate of less than 1 percent.11 Although almost all patients treated with the drug have prolongation of the QT interval, polymorphic ventricular tachycardia (i.e., torsades de pointes) is rare. Crcl <10 ml/min: Individualize dose. Despite such measures, bradycardia was progressive and terminal in 1 patient during the controlled trials.

In addition, no significant association was found between duration of overlap and rates of bradycardia (OR 1.00, 95% confidence interval (CI) 0.99-1.00, P = 0.08) or hypotension (OR 1.00, 95% CI 0.99-1.00, P = 0.21), which occurred in 35.9% and 47.3% of patients, respectively. Supplied: 200 mg, 300 mg tab (sulfate). Patients taking amiodarone should not eat grapefruit or drink grapefruit juice because it can inhibit the conversion of amiodarone to an active metabolite.

PULMONARY TOXICITY: This drug has several potentially fatal toxicities, the most important of which is pulmonary toxicity (hypersensitivity pneumonitis or interstitial/alveolar pneumonitis) that has resulted in clinically manifest disease at rates as high as 10% to 17% in some series of patients with ventricular arrhythmias given doses around 400 mg/day, and as abnormal diffusion capacity without symptoms in a much higher percentage of patients. Fernando HC, Jaklitsch MT, Walsh GL, et al. Amiodarone injection is used to treat life-threatening heart rhythm problems called ventricular arrhythmias. The objective of this study was to evaluate the safety and efficacy of varying durations of overlap when amiodarone IV infusion is transitioned to oral administration in cardiothoracic surgery patients.
