Semax is a synthetic melanocortin-derived heptapeptide developed in Russia as a neuroprotective, neuromodulatory, and cognitive-enhancing agent, where it is clinically utilized for conditions such as ischemic stroke, traumatic brain injury (TBI), cerebrovascular insufficiency, and various cognitive or neurodegenerative disorders. Its multifaceted pharmacological profile involves modulation of neurotransmitter systems, including dopaminergic and serotonergic pathways, as well as the upregulation of key neurotrophic and neuroprotective factors such as brain-derived neurotrophic factor (BDNF) and related signaling cascades that support synaptic plasticity, neuronal survival, and long-term cognitive function. Research demonstrates that Semax can reduce infarct volume, accelerate neurological recovery, and enhance functional outcomes following ischemic injury by mitigating excitotoxicity, oxidative stress, and inflammatory responses. Additionally, its protective actions extend to ocular and optic nerve health, with investigations exploring its potential in conditions such as optic nerve atrophy and glaucoma, where neurotrophic support and improved microcirculation are critical. While Semax is an established therapeutic in Russian clinical practice, its status in many other countries remains limited to experimental or nootropic use, where interest continues to grow due to its unique combination of neuroprotective, cognitive-enhancing, and cerebrovascular-supportive mechanisms.
