Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Sotalol (Betapace) and amiodarone (Pacerone) are both antiarrhythmic medications used to treat heart rhythm problems, but they have some key differences. Sotalol is a non-selective beta blocker and potassium channel blocker, while amiodarone works by blocking various receptors and channels in the heart. Sotalol is typically taken twice a day and requires a hospital stay of at least three days when starting. Amiodarone often starts with a high "loading dose" in the hospital and can take 1-3 weeks to work. Both medications are available as lower-cost generics. Amiodarone has a longer list of serious side effects, including lung and liver damage. It can stay in the body for many weeks, making its side effects potentially long-lasting. Both medications require close monitoring and have specific interactions with other medications, but Amiodarone has more severe and varied potential side effects compared to Sotalol.

Summary of Betapace vs. Nexterone
Summary for Antiarrhythmic
Prescription only
Sotalol (Betapace) is used to treat and prevent certain types of heart rate and heart rhythm problems (like atrial fibrillation or Afib). It's taken by mouth, typically twice a day. Usually, you need to start this medication in the hospital and stay there for at least 3 days so that the healthcare team can monitor your heart rhythm and check for any serious side effects. Sotalol (Betapace) can interact with several medications, including certain blood pressure medications and antacids. Sotalol is available both generic and brand name medications.
Summary for Antiarrhythmic
Prescription only
Amiodarone solution (Nexterone) is an antiarrhythmic medication. It's used to stabilize serious and life-threatening heart rhythm problems, like ventricular fibrillation (VF) and ventricular tachycardia (VT), when other treatment options haven't worked well. Amiodarone solution comes in premixed (brand name Nexterone) or concentrate formulations for infusion. It's given intravenously (IV) in a hospital setting under the supervision of a cardiology team. Common side effects of the infusion include low blood pressure, nausea, and slow heart rate.

Once the heart rhythm stabilizes, the cardiology team might transition you to amiodarone oral tablets (Pacerone).
