Metoprolol succinate is a beta blocker FDA-approved to treat hypertension (high blood pressure), arrhythmia (irregular heartbeat), and angina. It’s also commonly used with other medications or alone to treat heart failure and heart attacks.
It’s also sold under the brand name Toprol XL. Toprol XL (metoprolol succinate) is available as a tablet, capsule, and extended-release tablet. A healthcare provider may recommend regularly checking your blood pressure at home while taking the medication.
Toprol XL works by relaxing blood vessels and slowing the heart rate to improve blood flow and manage blood pressure. Metoprolol succinate reduces the effects of catecholamines to reduce how hard the heart is working.
