Metoprolol Succinate Tablets

Metoprolol Succinate is used to prevent angina attacks, to lower high blood pressure, to control irregular heartbeats, and prevent migraines. This is a prescription approved by the Food and Drug Administration (FDA).

Angina attack is the most common type of angina and chest pain that results from reduced blood flow to the heart. A lack of blood flow means your heart muscle isn’t getting enough oxygen. The pain is frequently caused by physical activity or emotional stress. This is a prevalent manifestation of cardiovascular disease. This occurs after you’ve exerted yourself physically. The symptoms tend to be temporary lasting up to 15 minutes in most cases.  You can have an episode of angina at any time of the day. However, you’re more likely to experience symptoms in the morning. The most common types are chronic stable angina and unstable angina. Angina symptoms may include:

  • Fatigue
  • Nausea
  • Sweating
  • Shortness of breath
  • Dizziness
  • Pain in your arms, jaw, neck, shoulder, or back accompanying chest pain
  • Chest pain or discomfort

Hypertension is also known as the silent killer. Most people with hypertension are unaware of the problem because it may have no warning signs or symptoms. For this reason, blood pressure must be measured regularly. Blood pressure is the force exerted by circulating blood against the walls of the body’s arteries. It is the major blood vessels in the body.

Arrhythmias describes as an irregular heartbeat. The heart may beat too slowly, too fast, too early, or irregularly. This happens when the electrical signals to the heart that coordinate heart betas are not working well. For instance, some people experience irregular heartbeats which may feel like a racing heart or fluttering. Many heart arrhythmias are harmless. However, if they are particularly abnormal, it can cause serious and even potentially fatal symptoms.

Migraine is a neurological condition that can cause multiple symptoms. It is often characterized by intense and debilitating headaches. It can last for hours to days band the pain can be so severe that it interferes with your daily activities. Migraine often runs in families and affects all ages. Changes in the brainstem and its interactions with the trigeminal nerve which is a major pain pathway might be involved. As a result, there might be imbalances in brain chemicals including serotonin which helps regulate pain in your nervous system. If the following symptoms are unusual for the person with migraine, they should not be ignored:

  • Visual disturbance
  • An unusually severe headache
  • Difficulties with speech
  • Loss of sensation

How does the medicine work?

Metoprolol Succinate is a type of medicine called beta-blocker.

The effects of Metoprolol mean that the heart doesn’t use as much energy to pump blood around the body. Angina chest pain occurs when the heart doesn’t get enough oxygen to meet demand. Metoprolol prevents angina attacks because it reduces the workload of the heart and so decreases its demand for oxygen.

This works in hypertension by blocking beta receptors that are found in the heart. This causes the heart to beat slower and less forcefully. By that, it lessens the pressure at which blood is pumped out of the heart and around the body and so lowers blood pressure.

In irregular heartbeats, this drug controls it because a slower heart rate tends to allow the electrical signals in the heart to fire more regularly. It lets the heart to beat more regularly. The effect of Metoprolol on the heart and circulation helps control symptoms that are associated with an overactive thyroid gland.
