What Is Metoprolol Tartrate 100mg?
Metoprolol tartrate is a beta-blocker, a type of medication that blocks the effects of adrenaline on the heart. This slows the heart rate, lowers blood pressure, and reduces how hard the heart has to work. It is FDA-approved to treat hypertension, long-term chest pain from angina, and to reduce the risk of death after a heart attack. Metoprolol tartrate is the immediate-release form and is usually taken more than once a day, unlike the extended-release succinate form.
