Introduction
In general, the main therapeutic effects of metoprolol succinate extended-release tablets include lowering blood pressure, slowing heart rate, improving symptoms of angina, protecting cardiac function, and alleviating symptoms related to hyperthyroidism. Additionally, during treatment with this medication, heart rate and blood pressure should be monitored regularly. The drug should not be discontinued abruptly without medical guidance; dosage adjustments must be made under the supervision of a physician.
Generally, the main effects of metoprolol succinate sustained-release tablets include lowering blood pressure, slowing heart rate, improving symptoms of angina pectoris, protecting cardiac function, and relieving symptoms related to hyperthyroidism. Specific details are as follows:
1. Lowering Blood Pressure
The drug blocks β-receptors in the heart and blood vessels, reducing cardiac output and decreasing vascular resistance, thereby helping to lower blood pressure. It is suitable for individuals with elevated blood pressure and helps maintain blood pressure within a normal range.
2. Slowing Heart Rate
The medication inhibits the activity of β1-receptors in the heart, reduces myocardial excitability, and slows down the heartbeat. It can be used to treat tachycardia, restoring heart rate to a normal rhythm and reducing the burden caused by excessive cardiac workload.
3. Improving Symptoms of Angina Pectoris
Angina is often caused by insufficient blood supply to the myocardium. This drug reduces heart rate and myocardial contractility, thereby decreasing myocardial oxygen consumption and improving the imbalance between oxygen supply and demand. As a result, it alleviates discomfort such as chest tightness and chest pain during angina attacks.
4. Protecting Cardiac Function
For patients with impaired cardiac function, this medication can be taken long-term. By suppressing sympathetic nervous system activity, it helps reduce cardiac remodeling, delays the progression of cardiac dysfunction, maintains normal cardiac pumping function, and improves patients' quality of life.
5. Relieving Symptoms Associated with Hyperthyroidism
Patients with hyperthyroidism often experience symptoms such as rapid heart rate and palpitations. This drug can slow heart rate and reduce excessive cardiac excitation, thereby relieving these symptoms and aiding in overall symptom management.
In addition, regular monitoring of heart rate and blood pressure is necessary during treatment. The medication should not be discontinued abruptly without medical guidance; dosage adjustments must be made under the supervision of a physician. Patients with conditions such as bronchial asthma or hypothyroidism should inform their doctor before starting the medication.
