- Selank
- GABAergic modulation via enkephalin upregulation
- Hyperarousal, startle response, autonomic dysregulation
- Multiple human RCTs in anxiety disorders; PTSD studies pending
- Strongest evidence for anxiety symptoms; minimal sedation or dependence risk
- Semax
- BDNF upregulation, NGF signaling, glutamate regulation
- Fear extinction, hippocampal neurogenesis, cognitive deficits
- Preclinical fear conditioning models; human cognitive enhancement trials
- Promising for extinction learning and cognitive symptom domain
- BPC-157
- Gut-brain axis repair, systemic anti-inflammatory, angiogenesis
- Neuroinflammation, autonomic tone, stress-induced GI pathology
- Extensive preclinical data; human case reports in various conditions
- Indirect mechanism; targets inflammation rather than neural circuits directly
- Cerebrolysin
- Neurotrophic factor delivery (BDNF, GDNF, CNTF)
- Hippocampal atrophy, cognitive impairment, emotional dysregulation
- Meta-analyses in stroke/TBI; limited PTSD-specific data
- Established safety profile; expensive; requires repeated IV administration
- Dihexa
- HGF/c-Met synaptogenesis, synaptic remodeling
- Fear memory reconsolidation, extinction circuit plasticity
- Preclinical cognitive models; early-phase human trials
- Most potent synaptogenic agent; oral bioavailability; long-term safety unknown
- Thymalin
- Immune modulation, HPA-axis cortisol feedback restoration
- Systemic inflammation, blunted cortisol response
- Eastern European literature; limited Western RCTs
- Addresses immune-endocrine dysregulation; less direct neural action
