Key takeaways
Metoprolol succinate (Toprol XL) and sotalol (Betapace) are both medications used to treat heart conditions, but they have different uses and properties. Metoprolol succinate is a selective beta blocker primarily used to treat high blood pressure, chest pain, and to lower the risk of hospitalization and death in heart failure. It is taken once daily and is available in both generic and brand name forms. On the other hand, sotalol is a non-selective beta blocker and potassium channel blocker used to treat and prevent certain heart rhythm problems like atrial fibrillation. Sotalol is typically taken twice daily and also comes in both generic and brand name forms. Unlike metoprolol, starting sotalol usually requires a hospital stay for monitoring due to the risk of serious side effects. Both medications can cause dizziness and tiredness, but sotalol has a higher risk of causing breathing problems and requires careful monitoring of heart rhythm. Additionally, metoprolol needs to be taken with food, while sotalol can be taken with or without food but should be consistent.
