Compare Norpace vs. Betapace

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Disopyramide (Norpace) and sotalol (Betapace) are both used to treat irregular heart rhythms, but they have some key differences. Disopyramide is an antiarrhythmic that slows down abnormal electrical activity in the heart and is available in both immediate-release and extended-release forms. Sotalol, on the other hand, is a non-selective beta blocker and potassium channel blocker that not only slows down electrical activity but also reduces heart rate. Sotalol is used to treat and prevent both ventricular arrhythmias and atrial fibrillation, while disopyramide is primarily for ventricular arrhythmias and is rarely used for atrial fibrillation due to higher risks. You need to start both medications in a hospital for close monitoring, but sotalol requires a longer stay of at least three days. Disopyramide can cause side effects like dry mouth and constipation, whereas sotalol can lead to vomiting and bronchospasm. Both medications have generic versions available, making them more affordable.
