Lemildipine is primarily used in the treatment of hypertension, effectively lowering high blood pressure by relaxing the blood vessels, which allows for smoother blood flow. It is also explored for its potential in managing angina, helping to reduce the frequency of chest pain episodes by improving blood supply to the heart muscle. Additionally, research has indicated its possible neuroprotective effects, suggesting a role in protecting nerve cells against damage, which could be beneficial in conditions like stroke or neurodegenerative diseases. Its application in these areas continues to be studied for broader therapeutic uses.
