Huperzine A, used for benign memory disorders and various types of dementia, memory cognitive function and emotional behavior disorders in the middle and elderly. It can also be used to treat myasthenia gravis
This product is a reversible cholinesterase inhibitor with selective inhibition of true cholinesterase. High biological activity, have higher fat soluble, small molecules, easy through the blood brain barrier, after entering the central mainly distributed in the brain's frontal lobe, temporal lobe and hippocampus is closely related with learning and memory areas of the brain, in low doses of acetylcholinesterase (AChE) has a strong inhibitory effect, make the distribution area of neural synaptic cleft acetylcholine (ACh) content increased significantly, Thus, it can enhance the excitatory conduction of neurons, strengthen the excitatory effect of learning and memory brain areas, and improve cognitive function, enhance memory retention and promote memory reproduction. Animal experiments have shown that the drug is absorbed quickly and completely, the bioavailability is 96%, the peak blood concentration can be reached in 10-30 minutes, the distribution very fast, and it is easy to cross the blood-brain barrier. The elimination half-life was 4 hours. The drug was excreted mainly in the form of urine and metabolites, and 73.6% of the drug dose was excreted in 24 hours.
