Cortexin improves brain metabolism. The drug is a lyophilisate obtained by acetic acid extraction from the cerebral cortex of cattle or pigs. It contains low-molecular active neuropeptides (molecular weight does not exceed 10,000 daltons) which penetrate easily the blood-brain barrier and directly affect nervous cells.
Cortexin has a tissue-specific multifunctional effect on the brain. It promotes metabolic regulation, neuroprotection, functional neuromodulation, neurotrophic activity.

Cortexin improves the energy metabolism of brain cells as well as intracellular protein synthesis.

Cortexin regulates the processes of lipid peroxidation in brain cells, reduces the formation of free radicals and blocks the processes of free radical oxidation. The drug eliminates the imbalance of inhibitory and excitatory amino acids and possesses a moderate GABAergic effect.

Cortexin has a positive effect in the violation of cognitive functions. It improves concentration of attention, short-term memory, learning ability, accelerates recovery of brain functions after stress and regulates serotonin and dopamine levels. Cortexin stimulates mental activity (no excessive activating influence) and reparative processes in the brain as well as restores the cerebral bioelectrical activity.


Complexity of the drug`s composition does not allow for the conducting of the usual pharmacokinetic analysis of individual components, since the Cortexin active substance consists of a complex of polypeptide fractions.


Cerebral circulation disorders, encephalopathy of various genesis, acute and chronic encephalitis and encephalomyelitis, vegetative-vascular dystonia; epilepsy, craniocerebral trauma and its consequences, asthenia, viral and bacterial neuroinfections, infantile cerebral palsy, psychomotor and speech retardation in children, cognitive disorders (dysfunction of memory and ideation), reduced learning capacity.
