Mechanism of Action
Cortexin's activity is attributed to its complex peptide mixture acting through multiple neurological pathways.
Neurotrophic Factor Stimulation
Cortexin administration increases expression of endogenous BDNF, NGF, and GDNF, neurotrophic factors supporting neuronal survival, axonal growth, and synaptic plasticity.Anti-Excitotoxicity
Components of cortexin reduce glutamate-mediated excitotoxicity by modulating NMDA receptor activity. This is relevant to stroke and TBI scenarios where glutamate overstimulation causes secondary neuronal death.Anti-Oxidant Neuroprotection
Cortexin increases superoxide dismutase (SOD) and catalase activity in brain tissue, reducing oxidative damage. It also reduces lipid peroxidation markers in ischemic brain regions.Research Summary
Stroke Recovery
Multiple Russian RCTs show Cortexin 10 mg IM daily for 10 days improves neurological deficits and functional outcomes in acute ischemic stroke when administered within 6 hours. Effect sizes are modest but consistent across studies.Cognitive Decline
In elderly patients with mild cognitive impairment, 10-day Cortexin cycles repeated quarterly show improvements on MMSE scores relative to controls in 6-month trials.Epilepsy
Cortexin as adjunct to standard antiepileptics reduces seizure frequency in pediatric studies (Russian literature).Calculate your Cortexin dose Vial strength, BAC water, exact syringe draw in IU. Free, no signup. Open Calc →
Research Protocols
Standard Cycle
10 mg IM once daily for 10 consecutive days. May repeat cycle after 3–6 months depending on indication.Reconstitution
Reconstitute with 1–2 mL of 0.9% saline or sterile water. Administer within 20 minutes of reconstitution.Administration Site
IM injection, alternating gluteus or deltoid.Storage & Handling
Store lyophilized" class="wiki-gloss-link">lyophilized vials at 2–8°C. Do not freeze. Reconstitute immediately before use and administer within 20 minutes. Do not store reconstituted solution.
