Metoprolol succinate
Summary
Metoprolol succinate is used to treat high blood pressure, chest pain (angina), and heart failure. It can also help prevent heart attacks.
Metoprolol succinate is a beta-blocker. It works by blocking certain signals in the heart, which slows the heart rate and reduces the heart's workload, thereby lowering blood pressure and preventing chest pain.
The dosage of Metoprolol succinate depends on the condition being treated. For high blood pressure, the starting dose is usually 25-100 mg once daily, with a maximum of 400 mg/day. For angina, it's 100-400 mg once daily. For heart failure, you start with 12.5-25 mg once daily and gradually increase to a target dose of 200 mg/day as tolerated. The medicine is taken orally, ideally with food.
Common side effects of Metoprolol succinate include tiredness, dizziness, depression, diarrhea, shortness of breath, slow heartbeat, and rash. More serious but less common side effects include worsening chest pain, heart attack, or heart failure.
Do not stop taking Metoprolol succinate suddenly without talking to your doctor, as this can cause serious heart problems. Avoid driving or operating machinery until you know how the medicine affects you. Also, avoid alcohol as it can increase the risk of side effects. If you have heart failure, tell your doctor if you gain weight or have shortness of breath.
Indications and Purpose
How does Metoprolol succinate work?
Metoprolol succinate works by blocking beta-adrenergic receptors in the heart, which reduces the effects of adrenaline. This leads to a slower heart rate and decreased force of heart contractions, resulting in lower blood pressure and improved blood flow. It also helps reduce the heart's oxygen demand, alleviating angina symptoms.
How does one know if Metoprolol succinate is working?
The benefit of Metoprolol succinate is evaluated by monitoring blood pressure, heart rate, and symptoms of angina or heart failure. Regular follow-up appointments with your doctor are important to assess the effectiveness and adjust the dosage if necessary. Self-monitoring of blood pressure at home can also be helpful.
Is Metoprolol succinate effective?
Metoprolol succinate has been shown in clinical trials to effectively lower blood pressure, reduce angina attacks, and improve survival rates after heart attacks.
