Butylphthalide is primarily used in the treatment of ischemic stroke due to its ability to improve cerebral blood flow and reduce neuronal damage. It is often administered in clinical settings to enhance recovery and minimize long-term neurological deficits. Additionally, it has shown potential in alleviating symptoms of vascular dementia by promoting brain cell survival and reducing oxidative stress. In traditional Chinese medicine, it is also utilized for its neuroprotective properties and to support overall brain health. Research continues to explore its efficacy in other neurological disorders, including Alzheimer's disease and migraine prevention.
