Selank® is an anxiolytic peptide drug with nootropic properties. By its structure, Selank is based on endogenous tetrapeptide Tuftsin, which plays an important role in immune system. To slow the breakdown of peptide and prolong its effects, the inventors of Selank added a Glyproline to its structure.

The mechanism of anxiolytic action is related to the regulation of norepinephrine, serotonin and enkephalins levels and their metabolism in the brain. It is suggested that another possible mechanism of action is inhibition of enkephalin-degrading enzymes, which increases the activity of endogenous opioid system and explains the mild analgesic effect of Selank.

Numerous clinical trials confirmed the safety of this peptide, which was found to not form a dependence and to be non-toxic even in doses 200-500 times higher than therapeutic ones.
