Selank – Nasal spray

Selank Nasal Spray is a compounded, investigational neuroactive peptide preparation primarily studied for anxiolytic, neuroprotective, cognitive-enhancing, and immunomodulatory effects. Typical pharmacy compounding produces a nasal spray at 1 mg/mL for both clinical research and off-label therapeutic use in anxiety disorders, cognitive dysfunction, and other neuropsychiatric or immunological indications.

Selank’s mechanism of action involves positive allosteric modulation of gamma-aminobutyric acid type A (GABA-A) receptors in the brain. By enhancing the affinity and activity of endogenous GABA at these inhibitory receptors, Selank has been studied for anxiolytic and calming effects. It also alters the gene expression involved in the GABAergic system, and secondarily regulates neuroimmune gene networks—including effects on cytokine balance, monoamine neurotransmitters (serotonin, dopamine), and antiviral pathways. This multi-modal action is proposed to underlie its anxiolytic properties and potential cognitive and immune effects.

Selank exhibits an excellent tolerability profile in clinical and preclinical studies. Rare adverse effects include mild nasal or throat irritation, transient headache, or dizziness. Allergic reactions are exceedingly rare, and there is no evidence for sedation, dependence, withdrawal, or systemic toxicity in published research. Monitoring is recommended for local irritation, psychological changes, or unexpected systemic effects.

Contraindications: Hypersensitivity to Selank or excipients; do not use in pregnancy, lactation, or pediatric populations due to insufficient data.
Precautions: Use caution in patients on other CNS-active drugs; human safety data, though encouraging, remain limited and off-label use should involve specialist oversight.
