Ascovertin improves dizziness metrics
[Clinical efficacy of a novel hemorheological drug ascovertin in patients with vascular encephalopathy].
Combination effects complicate isolation
Our exploration focused on the effectiveness of a treatment called ascovertin in patients suffering from stages I and II of vascular encephalopathy, often linked to atherosclerosis. This treatment, comprised of flavonoid dihydroquercetin and ascorbic acid, was administered over a period of 21 days to a group of 21 patients.

In contrast, we had a comparison group of 10 patients who did not receive ascovertin. The results were promising, revealing that those who took ascovertin experienced significant relief from headaches, decreased vertigo, and less overall fatigue. Furthermore, cognitive functions showed noticeable improvement.

Alongside these benefits, we noted a reliable reduction in whole blood viscosity, suggesting better blood flow and health of blood cells. Specifically, ascovertin appeared to enhance cellular rheology, which means our study participants demonstrated improved flexibility of red blood cells, reduced clumping, and lower levels of harmful lipid peroxidation in both their red blood cells and blood plasma.

However, it’s important to mention that because quercetin was part of a combination treatment, isolating its specific effect on dizziness is challenging. Thus, while benefits were observed, the distinct role of quercetin is not definitively determined in this context.
