Dosage and administration

Cortexin has an indication-specific dosing, with the most common regime being intramuscular injections once daily. Before injection dissolve content of vial in 1–2 ml of 0.5 % procain (novocain) solution, or water for injection or 0.9 % sodium chloride solution. Adults should use 10 mg per day for the period of 10 days. Cortexin must be taken in the first part of the day, before 3pm. Children weighing less than 20 kg should have 0.5 mg/kg, over 20 kg – 10 mg per day for the period of 10 days. If necessary, the course can be repeated after 3-6 months of discontinuation.

Way of Administration

Please use sterile needles, sterilize the administration site, wear sterile plastic gloves, administer as soon as you opened the vial. Please relax your muscle and inject slowly.

Side effects

No adverse reactions were observed during administration when taken as indicated. Individual hypersensitivity to the product components is possible, so please pay close attention to your body response when you administer the drug for the first time.

Cortexin® is a mixture of neuropeptide fractions, amino acids, vitamins and minerals, all of which have a pronounced but subtle positive effect on the brain. Similar to Cerebrolysin, Cortexin is based on neuropeptides and amino acids. However, there is a difference: Cortexin has significantly more peptide fractions and less amino acids.

Cortexin® has the following effects:

Nootropic effect: Improves higher cerebral functions, processes of learning and memory, concentration, attention and tolerance to mental and physical stress;

Neuroprotective effect: protects neurones against different endogenous neurotoxic factors (glutamate, calcium ions and free radicals) and reduces toxic impact of psychotropic agents;

Antioxidant effect: inhibits lipid peroxidation, increases survival of neurones under oxidative stress and hypoxia;

Tissue-specific effect: activates metabolism of neurones of central and peripheral nervous system as well as reparative processes; also, promotes stimulation of cortical function and general improvement of the nervous system.

Mechanism of action of CORTEXIN® is attributed to the following effects:

  • Activation of neuronal peptides and neurotrophic cerebral factors;
  • Optimisation of metabolic balance of excitatory and inhibitory amino acids as well as dopamine and serotonin;
  • GABAergic actions: reduction of the paroxysmal convulsive activity of brain, improvement of its bioelectrical activity and prevention of free radicals formation (products of lipid peroxidation).

Cortexin has the following amino acids, vitamins and minerals:
