What is Nicergoline?

Nicergoline (Sermion) is an ergot derivative used primarily to treat senile dementia and other disorders which are known to have a vascular origin. It is known to decrease vascular resistance and increase arterial blood flow within the brain, thus improving the utilization of oxygen and glucose uptake by brain cells.

What is the Mechanism of Action of Nicergoline?

The drug can improve cerebral and peripheral blood circulation. And it activates metabolism.

Nicergoline reduces vascular resistance, increases arterial blood flow and the consumption of oxygen and glucose by brain tissues. It lowers pulmonary vascular resistance. The drug reduces platelet aggregation and improves hemorheological parameters. It increases blood flow speed in the vessels.

At the same time it does not affect blood pressure. In patients with arterial hypertension, the drug can cause a gradual decrease in blood pressure.

What is Nicergoline Used For?

  • Cerebral atherosclerosis;
  • Thrombosis and embolism of cerebral vessels;
