Cortexin

Also known as: Polypeptide Extract

Routes

2 routes

Cortexin is a neuropeptide complex extracted from the cerebral cortex of young cattle or pigs, containing a mixture of low-molecular-weight neuropeptides, amino acids, vitamins, and minerals. Approved in Russia for neurological conditions, it promotes neurotrophic factor expression (BDNF, NGF), enhances GABAergic neurotransmission, and provides antioxidant neuroprotection. Clinical use spans pediatric neurology (cerebral palsy, epilepsy, delayed development) and adult neurology (stroke recovery, TBI, cognitive impairment).

Research Applications

Pediatric neurological disorders. Stroke recovery. Cognitive impairment. Epilepsy adjunct therapy.

Mechanism of Action

The neuropeptide mixture activates neurotrophic signaling pathways, enhances GABA-A receptor function, stabilizes calcium homeostasis, and reduces oxidative stress in neural tissue.

Biological Pathways

Neuroprotection, Cognitive issues, Brain injury
