Dronedarone



What are the uses of this medicine?[edit | edit source]

  • Dronedarone (MULTAQ) is used to lower the chance that you will need to go into the hospital for atrial fibrillation.
  • It is meant for people who have had certain types of atrial fibrillation (paroxysmal or persistent AF) in the past, but are now in normal rhythm.


How does this medicine work?[edit | edit source]

  • Dronedarone (droe ne’ da rone) is a synthetic derivative of amiodarone, a benzofuran derivative that is a structural analogue of thyroid hormone.
  • However, unlike amiodarone and thyroxine, dronedarone is not iodinated and was specifically designed to avoid some of the end-organ adverse effects associated with amiodarone use.
  • Dronedarone, like amiodarone, has a multitude of electrophysiologic properties, including inhibition of several potassium currents as well as sodium and slow L-type calcium channels.
  • In clinical trials, dronedarone improved maintenance of sinus rhythm in patients with atrial fibrillation or flutter.


Who Should Not Use this medicine ?[edit | edit source]

This medicine cannot be used in patients who:

  • have a certain type of heart problem called heart block, and you do not have an implanted pacemaker
  • have a slow heart rate, less than 50 beats each minute
  • have severe liver problems or had liver or lung problems after using amiodarone (a medicine for abnormal heart rhythm)

take certain medicines that can change the amount of MULTAQ that gets into your body. Do not use these medicines with MULTAQ:

take certain medicines that can lead to a dangerous abnormal heart rhythm:

  • are pregnant or plan to become pregnant. It is not known if MULTAQ will harm your unborn baby.
  • are breastfeeding or plan to breastfeed. It is not known if MULTAQ passes into your breast milk.
  • are allergic to dronedarone or any of the other ingredients in MULTAQ.


What drug interactions can this medicine cause?[edit | edit source]

  • MULTAQ and certain other medicines can react with each other, causing serious side effects.

Especially tell your doctor and pharmacist if you take:

  • Treatment with Class I or III antiarrhythmics (e.g., amiodarone, flecainide, propafenone, quinidine, disopyramide, dofetilide, sotalol) or drugs that are strong inhibitors of CYP3A (e.g., ketoconazole) must be stopped before starting MULTAQ


Is this medicine FDA approved?[edit | edit source]

  • Dronedarone was approved for use in the United States in 2009 and its current indications are for oral treatment of paroxysmal or persistent atrial fibrillation or flutter.

What special precautions should I follow?[edit | edit source]

  • Do not drink grapefruit juice while you are being treated with MULTAQ. Grapefruit juice can increase the amount of MULTAQ in your blood and increase the likelihood that you will have a side effect of MULTAQ.
  • MULTAQ doubles the risk of cardiovascular death (largely arrhythmic) and heart failure events in patients with permanent AF. Determine cardiac rhythm at least once every 3 months. If AF is detected discontinue MULTAQ or cardiovert.
  • New onset or worsening of heart failure has been reported during treatment with MULTAQ. In patients with permanent atrial fibrillation, dronedarone was associated with an increased risk of stroke, particularly in the first two weeks of therapy. Ensure appropriate antithrombotic therapy prior to and throughout MULTAQ use.
  • Hepatocellular liver injury, including acute liver failure requiring transplant, has been reported in patients treated with MULTAQ. If hepatic injury is suspected, discontinue MULTAQ.
  • Cases of interstitial lung disease including pneumonitis and pulmonary fibrosis have been reported in patients treated with MULTAQ. If pulmonary toxicity is confirmed, discontinue treatment.
  • Hypokalemia or hypomagnesemia may occur with concomitant administration of potassium-depleting diuretics. Maintain potassium and magnesium levels within the normal range.
  • Marked increase in serum creatinine, pre-renal azotemia and acute renal failure, often in the setting of heart failure or hypovolemia, have been reported in patients taking MULTAQ. Monitor renal function periodically.
  • Dronedarone caused fetal harm in animal studies at doses equivalent to recommended human doses. Women of childbearing potential should use effective contraception while using MULTAQ.


What to do in case of emergency/overdose?[edit | edit source]

  • There is no specific antidote available.
