Amiodarone is generally considered a class III antiarrhythmic drug, but it possesses electrophysiologic characteristics of all four Vaughan Williams classes. Consider alternative antiarrhythmic therapy if the patient experiences signs or symptoms of pulmonary toxicity. Grapefruit juice given to healthy volunteers increased amiodarone AUC by 50% and Cmax by 84%, resulting in increased plasma levels of amiodarone. Appearance of optic neuropathy and/or neuritis calls for re-evaluation of amiodarone therapy. Neither amiodarone nor DEA is dialyzable. The mean AUC and mean Cmax of the major metabolite of Amiodarone, DEA increased by 55% (range 58 to 101%) and 32% (range 4 to 84%), respectively, but there was no change in the Tmax in the presence of food. Although no dosage adjustment for patients with renal, hepatic, or cardiac abnormalities has been defined during chronic treatment with oral Cordarone, close clinical monitoring is prudent for elderly patients and those with severe left ventricular dysfunction. Amiodarone Hydrochloride Tablets, USP are available in bottles of 60 tablets and 500 tablets as follows: 200 mg, NDC 29300-359-16 and NDC 29300-359-05, white to off white round-shaped flat faced beveled edged tablets debossed with "U" over score on one side and "359" on other side. Phenytoin decreases serum amiodarone levels. The optimal dose for changing from intravenous to oral administration of Cordarone will depend on the dose of Cordarone I.V. may play a role in causing or exacerbating pulmonary disorders in those patients. When you are discharged from the hospital, take Amiodarone hydrochloride tablets exactly as your doctor tells you to take it. Suitable patients for dose adjustment were selected from a dosing survey population of those aged 60 years or over who were currently receiving amiodarone at a dosage of 200 mg or more daily. When changing to oral Cordarone therapy, clinical monitoring is recommended, particularly for elderly patients. Cordarone I.V. Interpreting elevated AST activity can be difficult because the values may be elevated in patients who have had recent myocardial infarction, congestive heart failure, or multiple electrical defibrillations. Give special attention to electrolyte and acid-base balance in patients experiencing severe or prolonged diarrhea or receiving drugs affecting electrolyte levels, such as diuretics, laxatives, systemic corticosteroids, or amphotericin B.
Renal: renal impairment, renal insufficiency, acute renal failure. This results in reduced Amiodarone serum levels and half-life. Adverse fetal effects associated with maternal Amiodarone use during pregnancy may include neonatal bradycardia, QT prolongation, and periodic ventricular extrasystoles, neonatal hypothyroidism (with or without goiter) detected antenatally or in the newborn and reported even after a few days of exposure, neonatal hyperthyroxinemia, neurodevelopmental abnormalities independent of thyroid function, including speech delay and difficulties with written language and arithmetic, delayed motor development, and ataxia, jerk nystagmus with synchronous head titubation, fetal growth restriction, and premature birth. There has been limited experience in patients receiving Cordarone I.V. In patients with implanted defibrillators or pacemakers, chronic administration of antiarrhythmic drugs may affect pacing or defibrillation thresholds.
Tablets in some patients. In surveys of almost 5,000 patients treated in open U.S. studies and in published reports of treatment with Amiodarone hydrochloride, the adverse reactions most frequently requiring discontinuation of Amiodarone hydrochloride included pulmonary infiltrates or fibrosis, paroxysmal ventricular tachycardia, congestive heart failure, and elevation of liver enzymes. at a much higher loading dose concentration and much faster rate of infusion than recommended in Dosage and Administration. There have been reports of QTc prolongation, with or without TdP, in patients taking amiodarone when fluoroquinolones, macrolide antibiotics, or azoles were administered concomitantly.
Patients whose arrhythmias have been suppressed by Cordarone I.V. Corneal microdeposits appear in the majority of adults treated with Amiodarone hydrochloride. Talk to your healthcare provider if you have concerns about fertility. Cases of optic neuropathy and optic neuritis, usually resulting in visual impairment and sometimes permanent blindness, have been reported in patients treated with Amiodarone and may occur at any time during therapy. Amiodarone is considered a class III antiarrhythmic drug, but it possesses electrophysiologic characteristics of all four Vaughan Williams classes.
If you get serious side effects during treatment you may need to stop Amiodarone hydrochloride tablets, have your dose changed, or get medical treatment. Only 1 of more than 1000 patients treated with Cordarone I.V. The CYP3A isoenzyme is present in both the liver and intestines. Cordarone I.V. contains the preservative benzyl alcohol (see DESCRIPTION). for longer than 3 weeks. The refractory period is prolonged in all cardiac tissues. These recommendations are made on the basis of a comparable total body amount of amiodarone delivered by the intravenous and oral routes, based on 50% bioavailability of oral amiodarone. Findings have included pulmonary infiltrates and/or mass on X-ray, bronchospasm, wheezing, fever, dyspnea, cough, hemoptysis, and hypoxia. CordaroneÃ? The incidence of thyroid tumors was greater than control at the lowest dose level tested, i.e., 5 mg/kg/day (approximately 0.08 times the maximum recommended human maintenance dose*). There is evidence that the time to effect is shorter when a loading-dose regimen is used.

Discontinue Amiodarone hydrochloride if the patient experiences signs or symptoms of clinical liver injury [see Warnings and Precautions (5.3)]. Initiate antiarrhythmic at a lower than usual dose and monitor patient carefully. Repeat history, physical exam, and chest X-ray every 3 to 6 months [see Warnings and Precautions 5.2)]. The concentrations and rates of infusion provided in Dosage and Administration reflect doses identified in these studies. Hyperthyroidism occurs in about 2% of patients receiving Cordarone, but the incidence may be higher among patients with prior inadequate dietary iodine intake.
Because of Amiodarone's long half-life, expect drug interactions to persist for weeks to months after discontinuation of Amiodarone.
