Cytidine diphosphorylcholine injection is mainly used in the clinical treatment of stroke, vascular dementia, brain and spinal cord injury, and glaucoma. Its main mechanism of action is: 1. Cytodiphosphocholine can reduce neurotransmitter-induced cell death by decreasing glutamate concentration in brain tissue. At the same time, cytidine phosphorylcholine can also play a neuronal protective role by increasing the concentration of ATP in the cerebral cortex and neostriatum.2. Cytidine phosphorylcholine injection can improve the spatial orientation and memory deficits caused by ischemia, and its main mechanism is to increase the activity of hippocampal acetylcholinesterase ATPase and improve cholinergic neurotransmission, which plays a role in improving memory and cognitive function.3. In the treatment of brain and spinal cord injury, cytidylcholine can reduce hippocampal neuronal loss and cortical contusion and improve neuronal function.
