Mechanism of ActionCerebrolysin contains neurotrophic factors that mimic BDNF, NGF, and CNTF activity. It enhances neuroplasticity, protects neurons from excitotoxicity, promotes neurogenesis, and improves synaptic function.Semax increases BDNF and NGF expression, modulates dopamine and serotonin systems, and has anti-inflammatory effects in the brain. It enhances neuroplasticity and protects neurons from oxidative stress and excitotoxicity.
