161 Likewise, coadministration with The data Show that the mechanism of digoxin-amiodarone interaction is multifactorial and emphasize the need for close monitoring of serum digoxin levels and clinical features during concurrent digoxin-amiodarone therapy
Amiodarone is a potent antiarrhythmic agent that is used to treat ventricular arrhythmias and atrial fibrillation
Adult patients with AF and received digoxin treatment from random samples of 1,000,000 individuals covered by the National Health Insurance in Taiwan were included
Whether patients with AF receiving digoxin-amiodarone combination therapy were in similar risk was unknown

Mechanisms of digoxin-amiodarone interaction in the rat Proc Soc Exp Biol Med The inhibition of the renal tubular uptake of digoxin caused by amiodarone may explain in part the increased serum digoxin concentration observed in vivo
Amiodarone is a benzofuran derivative, anti-arrhythmic drug used commonly in a variety of settings
0to 3
(1-5) The most common dose of amiodarone used ranged from 400 - 1600 mg per day
5 It is a common agent used to manage atrial fibrillation and the symptoms of heart failure
By inhibiting Na+/K+ ATPase, digoxin increases intracellular sodium, which increases sodium-calcium exchange by the Na+/Ca2+ exchanger (INCX) during Phase 1 of the cardiac action potential
The patient remained tachycardic (120 beats/min), so digoxin was restarted at half the dose, along with amiodarone 600 mg/24hr
Digoxin is a medication used to manage and treat heart failure and certain arrhythmias, and abortion
(See "Cardiac excitability, mechanisms of arrhythmia, and The following are key points to remember from the American Heart Association Scientific Statement on Recommendations for Management of Clinically Significant Drug-Drug Interactions (DDIs) With Statins and Select Agents Used in Patients With Cardiovascular Disease (CVD): A DDI is a pharmacokinetic or pharmacological influence of one medication Amiodarone is an antiarrhythmic medication used to treat and prevent a number of types of cardiac dysrhythmias
Data demonstrate that there is a clinically significant drug interaction
What is the mechanism by which amiodarone increases digoxin concentrations? Amiodarone-digoxin interaction: Clinical significance, time course of development, potential pharmacokinetic mechanisms and therapeutic implications Amiodarone-Digoxin Interaction
Coadministration of amiodarone and digoxin may increase digoxin serum levels
Fig
Minor episodes of bleeding Warfarin's hepatic metabolism and protein binding are the most common mechanisms for the occurrence of drug-drug interactions
Amiodarone (Cordarone) is a commonly prescribed medication for the management of both atrial and ventricular arrhythmias
This is roughly 50-fold higher than the daily recommended iodine intake for adults
2,3 Therefore, many patients will have an indication for concomitant warfarin and amiodarone therapy
30 Quinidine, verapamil, and amiodarone, among others, may significantly increase the SDC, and the digoxin dose should be reduced accordingly
See the list of drugs that interact with Digoxin
Evidence: The boy, who had paroxysmal supraventricular tachycardia, had been receiving atrial stimulation, amiodarone, propranolol and oral digoxin [Lanoxin]
Amiodarone is metabolized hepatically and serves as a substrate primarily for cytochrome P-450 (CYP) 3A4
An event is serious (based on the ICH definition) when the patient outcome is: * death * life-threatening * hospitalisation * disability Acute amiodarone therapy results in a use-dependent inhibition of inward sodium Kannan R, Hendrickson J, et al
Digoxin
This agent appears to have a marked effect on the kinetics of some commonly used cardiovascular drugs, such as warfarin, digoxin, quinidine, and procainamide, and has dynamic interactions with others, such as the beta blockers MECHANISMS OF INTERACTIONCytochrome P-450 enzyme system
Most frequently it is used for atrial fibrillation, atrial flutter, and heart failure
Amiodarone can also affect the heart, leading to sinus bradycardia, as well as arrhythmias such as AV block and QT prolongation
12 Therefore, since digoxin is a major substrate for P-gp and amiodarone is a known inhibitor of P-gp, the primary mechanism by which amiodarone increases digoxin concentrations is

Food and Drug Administration (FDA) specifically for the treatment of life-threatening
Whether patients with AF receiving digoxin-amiodarone combination therapy were in similar risk was unknown
Amiodarone is known to raise serum digoxin levels
Amiodarone-digoxin interaction: clinical significance, time course of development, potential pharmacokinetic mechanisms and therapeutic implications
Amiodarone is known to raise serum digoxin levels
The major mechanism of its drug interactions is inhibition of hepatic metabolism, but it can also affect the bioavailability, protein binding and renal excretion of coadministered drugs
0to 3
60 Recently, a large retrospective analysis demonstrated increased mortality in those receiving a combination of digoxin and amiodarone versus those taking digoxin alone
7 to 3
Minor episodes of bleeding A number of small studies and case reports have documented the increases in digoxin concentration when being administered with amiodarone
When initiating amiodarone in a patient receiving warfarin, the dose of warfarin should be
We have investigated the influence of amiodarone on digoxin pharmacokinetics and tissue distribution in the rat
