Cortagen (cerebro, sistema nervioso central)
Cortagen 20mg (Bioregulator) 
Cortagen is a bioregulatory peptide with primary effects in the brain and central nervous system. It has secondary effects on the immune system and in cardiac tissue. Research shows that it is a powerful regulator of the inflammatory response, particularly in the nervous system, helping to restore balance and proper functioning between pro- and anti-oxidative processes. It has been investigated as a potential treatment following ischemic brain injury where it and similar compounds have shown beneficial long-term results. Cortagen stimulates interleukin-2 expression and helps to regulate immune function primarily by reducing autoimmune reactions.
Cortagen has shown to be a correcting agents for functional and metabolic disorders in the brain caused by chronic ischemia. In an experiment with ischemic rats, both drugs were found to accelerate the recovery of individual behavior and prevent excessive activation of lipid peroxidation and decrease in antioxidant activity in brain tissues. These results suggest that cortexin and cortagen may be useful for improving the efficacy of neuroprotective therapy in cases of chronic brain ischemia. Additionally, it has been observed that cortagen has therapeutic effects on posttraumatic recovery of peripheral nerve tissue, as well as on cardiovascular and cerebrovascular parameters in humans.
