Metoprolol ER succinate, also known as metoprolol succinate, is a medication that belongs to the class of beta-blockers. It is commonly used to treat high blood pressure, chest pain (angina), and certain heart-related conditions. The “ER” in metoprolol ER succinate stands for extended release, which means that the medication is designed to release slowly into the body, providing a steady and consistent dose of the active ingredient, metoprolol, over a longer period.
Understanding Beta-Blockers
Beta-blockers are a class of medications that work by blocking the effects of the hormone epinephrine, also known as adrenaline. Epinephrine is a hormone that stimulates the heart to beat faster and with more force, increasing blood pressure. By blocking the effects of epinephrine, beta-blockers such as metoprolol ER succinate help to slow the heart rate and reduce blood pressure. This can be beneficial for people with high blood pressure, as it can help to reduce the risk of heart attack, stroke, and other cardiovascular problems.
How Metoprolol ER Succinate Works
Metoprolol ER succinate works by selectively blocking the beta-1 receptors in the heart. This helps to reduce the heart rate and the force of the heart’s contractions, which in turn reduces blood pressure. The medication also helps to reduce the amount of oxygen the heart muscle needs, which can help to relieve chest pain (angina) and improve exercise tolerance.
Conditions Treated with Metoprolol ER Succinate
Metoprolol ER succinate is used to treat a variety of conditions, including:
- High blood pressure (hypertension)
- Chest pain (angina)
- Heart failure
- Irregular heartbeat (arrhythmia)
- Myocardial infarction (heart attack)
Benefits of Metoprolol ER Succinate
The benefits of metoprolol ER succinate include:
- Improved blood pressure control: Metoprolol ER succinate helps to reduce blood pressure, which can reduce the risk of heart attack, stroke, and other cardiovascular problems.
- Relief from chest pain: The medication helps to reduce the frequency and severity of chest pain (angina) attacks, improving exercise tolerance and overall quality of life.
- Reduced risk of heart failure: Metoprolol ER succinate has been shown to reduce the risk of heart failure in people with a history of heart attack or other cardiovascular conditions.
- Improved survival rates: Studies have shown that metoprolol ER succinate can improve survival rates in people with heart failure or a history of heart attack.
Potential Side Effects

- Heart block: The medication can worsen heart block, a condition where the heart beats too slowly.
- Low blood pressure: Metoprolol ER succinate can cause low blood pressure, particularly when standing up from a sitting or lying position.
- Pregnancy and breastfeeding: The medication should be used with caution in pregnant or breastfeeding women, as it may affect the fetus or baby.
Dosage and Administration
The dosage of metoprolol ER succinate varies depending on the condition being treated and individual factors, such as medical history and other medications being taken.
