What are the efficacy and functions of Puerarin Injection?

Generally, the effects and functions of Puerarin Injection include protecting myocardial cells, anti-arrhythmia, anti-inflammatory and analgesic effects, vasodilation, and antioxidant properties. If necessary, it is recommended to use under a physician's guidance. The analysis is as follows:

1. Protection of Myocardial Cells

Puerarin regulates energy metabolism, such as promoting glucose utilization and reducing the expression of apoptosis-related proteins in myocardial cells, thereby enhancing the myocardium's tolerance to hypoxia. It can help reduce myocardial damage during treatment of myocardial infarction or heart failure.

2. Anti-Arrhythmic

Puerarin prolongs the action potential duration of myocardial cells, inhibits potassium ion efflux, and regulates sodium/calcium ion channel stability. This electrophysiological effect helps correct rapid arrhythmias and restore normal cardiac rhythm.

3. Anti-Inflammatory and Analgesic Effects

Puerarin Injection has significant anti-inflammatory and analgesic effects. Its mechanism mainly involves inhibiting the release of inflammatory mediators and leukocyte infiltration, thereby reducing inflammatory responses, while also regulating pain signal transmission.

4. Vasodilation

Puerarin can dilate blood vessels, especially showing significant dilation effects on cerebral and coronary arteries, thus improving blood supply to the brain and heart, playing a positive role in the prevention and treatment of cardiovascular and cerebrovascular diseases.

5. Antioxidant

Puerarin has strong antioxidant capabilities, effectively scavenging free radicals in the body, reducing oxidative stress injury, and simultaneously exerting certain anti-inflammatory effects to alleviate inflammatory responses.

Despite the multiple aforementioned benefits of Puerarin Injection, potential side effects and contraindications, such as allergic reactions and hypotension, should be considered during use.
