Stopping the infusion and restarting at a slower rate may help if infusion-related reactions occur. Hypotension is the most common adverse effect seen with intravenous amiodarone. Patients taking amiodarone should not eat grapefruit or drink grapefruit juice because it can inhibit the conversion of amiodarone to an active metabolite. A patient started on oral (PO) amiodarone approximately 1 week ago (400 mg/day). Adenosine is thought to exert its pharmacological effects through activation of purine receptors (cell-surface A1 and A2 adenosine receptors). However, the drug has many other effects: it slows heart rate and atrioventricular nodal conduction (via calcium channel and beta-receptor blockade), prolongs refractoriness (via potassium and sodium channel blockade), and slows intracardiac conduction (via sodium channel blockade). Cordarone I.V is not intended for maint therapy. Dosing (adults): Ventricular arrhythmias: Oral: 1200-1800 mg/day in 3 divided doses, up to 2400 mg/day.

Amiodarone reduces warfarin clearance and can lead to sudden and pronounced increases in the prothrombin time and International Normalized Ratio.21 The peak effects of interaction occur approximately seven weeks after initiation of therapy. Because implantable cardioverter-defibrillators (ICDs) are more effective than amiodarone in reducing mortality in high-risk patients with previous myocardial infarction, primary treatment should be an ICD.69 [Reference6 Evidence level A, meta-analysis] In these patients, amiodarone may be used as an adjunct to reduce the frequency of ICD shocks or to control atrial fibrillation in selected highly symptomatic patients. After a single dose of intravenous amiodarone in cirrhotic patients, significantly lower Cmax and average concentration values are seen for DEA, but mean amiodarone levels are unchanged. Drugs for Conversion of Atrial Fibrillation | AAFP (an inline 0.22 micron filter should be used). Manifestations of life-threatening toxicity include severe ventricular arrhythmias such as ventricular tachycardia or ventricular fibrillation, or progressive bradyarrhythmias such as severe sinus bradycardia or second or third degree heart block not responsive to atropine. Amiodarone is generally considered a class III antiarrhythmic drug, but it possesses electrophysiologic characteristics of all four Vaughan Williams classes.

IV to oral transition (infusion duration [assuming 0.5 mg/min infusion]: initial oral daily dose). 2014 AATS guidelines for prevention and management of perioperative atrial fibrillation and flutter for thoracic surgical procedures. WARNINGS Recommendations for conversion to intravenous amiodarone after oral administration: During long-term amiodarone therapy (ie, 4 months), the mean plasma-elimination half-life of the active metabolite of amiodarone is 61 days. Although no dosage adjustment for patients with renal, hepatic, or cardiac abnormalities has been defined during chronic treatment with oral amiodarone, close clinical monitoring is prudent for elderly patients and those with severe left ventricular dysfunction. Amiodarone is a potent inhibitor of the hepatic and renal metabolism of several drugs (Table 3).4,2125 Amiodarone inhibits metabolism through several cytochrome P450 pathways, including CYP 2C9 (which metabolizes warfarin [Coumadin]), CYP 2D6 (which metabolizes several beta blockers and narcotics), and CYP 3A4 (which metabolizes cyclosporine [Sandimmune] and calcium channel blockers).

Not preferred drug for PSVT because it is not rapidly effective (may take up to 60 minutes). Factors that increase likelihood of digoxin toxicity: Hypokalemia, hypomagnesaemia, hypothyroidism, renal dysfunction, interacting drugs (eg quinidine, verapamil). Amiodarone is more effective than sotalol or propafenone in preventing recurrent atrial fibrillation in patients for whom a rhythm-control strategy is chosen. Amiodarone injection belongs to the group of medicines known as antiarrhythmics. <> Laboratory studies to assess liver and thyroid function should be performed at least every six months. Because phlebitis may occur, the drug should be given through a central venous line when possible. The net effect is to shift the equilibrium away from binding of digoxin to its receptors in the body, thereby reversing its effects. The relationship between plasma amiodarone concentrations and effect, as well as the contribution of the metabolite DEA, is not well established.2 Routine monitoring of the amiodarone plasma level is not recommended.4 [Evidence level C, consensus/expert guidelines], Amiodarone is approved for use in the secondary prevention of life-threatening ventricular arrhythmias. Interactions with warfarin and digoxin are the most clinically important. May consider giving 10 vials, observing the patient's response, and following with an additional 10 vials.
