Vinpocetine is a cerebral vasodilator. It has a strong effect on vincamine and selectively increases cerebral blood flow; it can increase and improve the supply of cerebral oxygen, promote metabolism, enhance the deformability of red blood cells, reduce blood viscosity, and inhibit platelets. Aggregate, improve brain tissue metabolism. Mainly used for the treatment of sequelae of cerebral infarction, sequelae of cerebral hemorrhage, cerebral arteriosclerosis, etc. It is also used to treat retinal vascular sclerosis and vasospasm, deafness and vertigo in the elderly. Vinpocetine is a semi-synthetic vincamine derivative. The effect is similar to that of vincamine, and it has a high selective expansion effect on cerebral blood vessels.

Pharmacological effects are as follows:

① Inhibit the activity of calcium-dependent phosphodiesterase, increase the cAMP content of relaxing vascular smooth muscle, thereby relaxing vascular smooth muscle and increasing cerebral blood flow.

②Enhance the deformability of red blood cells, reduce blood viscosity, inhibit platelet aggregation, thereby improving blood fluidity and microcirculation.

③Promote the uptake of glucose in the brain tissue, and promote the metabolic transformation of monoamines in the brain.

④In cerebral ischemia, it can inhibit the increase of lactic acid in the brain, increase the content of ATP, inhibit the production of lipid peroxides in the brain, and delay the occurrence of cerebral ischemia spasm, so it can improve brain metabolism and protect brain function.

Vinpocetine is commonly used in cerebral arteriosclerosis, sequelae of cerebral ischemic and hemorrhagic stroke, transient ischemic attack and other cerebral circulation disorders, and is also used for the treatment of symptoms caused by cerebral circulation disorders, such as aphasia, It is widely used as a first-line drug for the treatment and prevention of ischemic cerebrovascular disease due to inability to use, poor memory, cognitive dysfunction, dizziness, headache and other cerebral vestibular problems.
