Selank is a synthesized analog of the endogenous peptide Taftcin. The drug has an original mechanism of neuro-specific action on the central nervous system. Selank has antianxiety, antidepressant and antiasthenic effects. It removes symptoms of anxiety, fear, apathy, depression and asthenia. Selank has a positive effect on cognitive functions; it improves memory, speech, increases attention and activates learning processes, in particular, remembering, analyzing and reproducing information. The drug normalizes psychomotor reactions. Selank removes the emotional strain, stress and stimulates adaptive behaviour, aimed at achieving set targets.


Selank is administered intranasally (nasal drops). Absolute bioavailability of the drug is 92.8%. The drug is quickly absorbed from the nasal mucosa and after 30 seconds is detected in the blood plasma; then the substance is quickly distributed to organs and tissues (including brain tissue).

Concentration of the drug in the blood plasma progressively decreases within 5-5.5 minutes. Neither unchanged drug nor its metabolites can be found in the urine due to the fast degradation of Selank under the influence of tissue peptidases.

At the first use remove the plastic screw cap and replace it with an enclosed pipette with a cap. Draw up the drug into the pipette.

The drug is instilled into the nasal passages in a sitting position with the head slightly thrown back or tilted to one side, after that each nostril is held with a finger for a short time.
The absorption effectiveness may decrease in case of increased rheum that is why it is recommended to clean the nasal passage before the drug instillation.
