Vinpocetine is mainly used in the treatment of cerebral infarction sequela, cerebral hemorrhage sequelae, cerebral arteriosclerosis, etc. It can also used in the treatment of retinal vascular sclerosis and blood vessel spasm, the elderly deafness, and dizziness.

1. Inhibit the activity of calcium dependency phosphodiesterase, increase the content of cAMP which can relax vascular smooth muscle, then relax vascular smooth muscle, and further increase cerebral blood flow.
2. Enhance the capacity of deformation of red blood cells, reduce blood viscosity, inhibit platelet aggregation, and thus improve blood flow and microcirculation.
3. Promote the brain tissue to absorb glucose, and promote the transformation of brain monoamine metabolism.
4. Inhibit the increase of brain lactic acid during cerebral ischemia, increase the ATP content, inhibit the generation of lipid peroxide in the brain, delay the occurring of spasm caused by cerebral ischemia, have the function of improving cerebral metabolism and protecting brain.
