The efficacy and function of morphine sulfate sustained-release tablets

Generally, morphine sulfate sustained-release tablets have analgesic, sedative, antitussive effects, can reduce the burden on the heart, and alleviate symptoms of cardiac asthma. The specific effects are as follows:

1. Analgesic Effect: The primary function of morphine sulfate sustained-release tablets is pain relief, particularly suitable for the treatment of severe cancer pain. It can effectively alleviate pain symptoms in patients and improve their quality of life.

2. Sedative Effect: In addition to pain relief, morphine sulfate sustained-release tablets also have a significant sedative effect. They can help patients remain calm, reduce negative emotions such as anxiety and fear, and alleviate mental stress caused by pain.

3. Antitussive Effect: Morphine sulfate sustained-release tablets also have a certain antitussive effect. Although primarily used for pain management, they can also be used in some cases to relieve cough symptoms, especially those caused by pain or irritation.

4. Reducing Cardiac Burden: In patients with myocardial infarction or normal blood pressure, morphine sulfate sustained-release tablets can calm the patient and reduce the burden on the heart. This helps stabilize the patient's condition and provides favorable conditions for subsequent treatment.

5. Alleviating Symptoms of Cardiac Asthma: Morphine sulfate sustained-release tablets can also be used to treat cardiac asthma, providing temporary relief from pulmonary edema symptoms. By dilating the bronchi and reducing lung inflammation, they improve the patient's respiratory condition.

Morphine sulfate sustained-release tablets are prescription medications and must be used under the guidance of a physician. During use, it is important to strictly follow medical instructions, paying attention to proper administration, dosage, and potential adverse reactions. Additionally, due to the addictive nature of morphine sulfate sustained-release tablets, long-term or excessive use should be avoided to prevent dependency and other serious issues.
