- Cerebrolysin
- BDNF/NGF mimetic; enhances neurotrophic signaling in hippocampus and amygdala
- Yes (receptor-mediated transcytosis)
- 0.5–2.0 mL/kg IM daily × 10–21 days
- 40–60% increase in hippocampal BDNF mRNA; improved fear extinction in rodent models
- Gold standard for neurotrophic enhancement in panic research. Strongest evidence base
- Selank
- GABA-A receptor upregulation; tuftsin-derived anxiolytic without tolerance
- Yes (via Met-enkephalin transport pathway)
- 0.1–0.3 mg/kg SC daily or BID
- No receptor downregulation after 21-day dosing; anxiolytic effect comparable to diazepam without sedation
- Best choice for GABAergic modulation studies without benzodiazepine-like tolerance
- P21
- CNTF-derived; JAK-STAT pathway activation; promotes hippocampal neurogenesis
- Yes (small peptide, lipophilic modifications)
- 1–5 mg/kg IP or SC
- Enhanced dentate gyrus neurogenesis; improved stress resilience in chronic unpredictable stress models
- Optimal for structural neuroplasticity endpoints. Less direct anxiolytic evidence
- Dihexa
- HGF/c-Met receptor agonist; synaptogenesis promoter
- Yes (orally bioavailable in some formulations)
- 0.1–1.0 mg/kg PO or SC
- Seven orders of magnitude greater synaptogenic potency than BDNF in vitro
- Strongest synaptogenesis signal but fewer panic-specific studies. Use in cognition-anxiety comorbidity models
- Thymalin
- Thymic peptide; HPA axis modulation; cortisol normalization
- Limited (peripheral immune effects predominate)
- 5–10 mg IM 2–3× weekly
- Reduced stress-induced cortisol elevation; indirect GABAergic restoration via HPA regulation
- Secondary choice. Use when neuroimmune or HPA dysregulation is the research focus
