Mechanism of action

Noopept is not a racetam (due to not having a 2-oxo-pyrrolidine skeleton), but is generally grouped together in the same category because it shares similar mechanisms of action with the racetam family, mainly modulation of the acetylcholine system, as well as modulation of AMPA receptors. When compared to traditional racetams, it has been found to be, according to studies, 1000 times more potent than the prototypical racetam drug, piracetam. Noopept is a prodrug for the endogenous peptide cycloprolylglycine.
