Huperzine-A 99%

Huperzine A is an organic compound with the chemical formula C15H18N2O. It is mainly used as a cholinesterase inhibitor for benign memory disorders in middle-aged and elderly people and various types of dementia, cognitive memory function and emotional and behavioral disorders. It can also be used for Benign memory disorders and various types of dementia, cognitive memory function and emotional and behavioral disorders in middle-aged and elderly people. Treatment of myasthenia gravis.

Huperzine-A 99%, as a potent acetylcholinesterase inhibitor, can easily cross the blood-brain barrier into the central nervous system and bind with acetylcholinesterase, thus inhibiting acetylcholinesterase in the brain, thus reducing the breakdown of acetylcholine, increasing the concentration of acetylcholine inside the brain, and improving the signalling between synapses. It is worth mentioning that this inhibitory effect of sarcosine A is reversible, when the concentration of acetylcholine reaches a certain level, it can be separated from acetylcholinesterase.

1.Pay attention to the dose

The daily dose of huperzine A should not be more than 0.45mg, otherwise it is easy to lead to systemic cholinergic system over-excitement, resulting in dizziness, nausea, vomiting, sweating and other side effects, and in serious cases, even lead to blurred vision, changes in heart rate, salivation and other adverse reactions.

Severe reactions can be oral atropine to achieve the effect of relief.

3.Pay attention to the mixing of drugs

Clinical treatment of dementia often need to combine a variety of drugs, so in the use of huperzine A should also be combined with nutritive brain cell drugs or improve cerebral circulation drugs, so that multiple perspectives to improve the nutrition and metabolism of the brain cells, and together to promote the improvement of brain function.
