Phenylpiracetam hydrazine has shown significant efficacy in the treatment of neurodegenerative diseases such as Alzheimer's disease and vascular dementia. Its core mechanism includes:
Dopaminergic system regulation: enhances working memory task performance by upregulating dopamine D1 receptor expression in the prefrontal cortex. For example, a randomized controlled trial of 60 patients with mild to moderate Alzheimer's disease showed that after 12 weeks of treatment, patients' MMSE scores increased by 2.3 points (control group increased by 0.8 points, p<0.05), and no dependence or withdrawal reactions were observed.

Activation of energy metabolism: promotes ATP production in the brain and enhances glucose utilization efficiency. Clinical data shows that after 3 days of treatment, the brain glucose metabolism rate of patients increased by 12%, which is positively correlated with the improvement of cognitive function scores.
