Key takeaways
Losartan (Cozaar) and sotalol (Betapace) are both prescription medications, but they are used for different health conditions and belong to different drug classes. Losartan is an angiotensin II receptor blocker (ARB) primarily used to lower blood pressure and protect against stroke, as well as to slow down kidney problems in people with diabetes. It is taken once daily and is available in a lower-cost generic form. 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 a day and also comes in a generic form. Unlike losartan, starting sotalol usually requires a hospital stay for monitoring due to the risk of serious side effects like abnormal heart rhythms. While losartan mainly affects blood pressure, sotalol works by slowing down electrical activity in the heart to manage arrhythmias. Both medications can cause dizziness and fatigue, but sotalol has additional risks like breathing problems and low blood sugar levels, especially in people with diabetes.
