Science
Mechanism of Action
Claimed to supply neuromodulatory peptides and amino acids that support neuronal metabolism after injury. Quality of evidence is limited outside regional literature.
Targets
CNS metabolism (proposed)
Studies
- Cortexin clinical literature (regional)— Journal/year not available
Benefits
Regional stroke/nootropic literature
Potential Side Effects
- Allergy to animal protein
- Injection reactions
