Modulates cholinergic neurotransmission by preventing scopolamine-induced decreases of acetylcholine in the hippocampus and cortex. Enhances D-aspartate release and modulates AMPA receptor activity. Demonstrates mild stimulatory properties without affecting dopaminergic or serotonergic systems, making it a 'cleaner' cognitive enhancer among racetams.

Contains oroxylin A — a flavonoid that inhibits PDE (phosphodiesterase), increases BDNF, and modulates dopamine signaling. Enhances focus and motivation without stimulant side effects. Also acts as a mild MAO-B inhibitor, preserving dopamine levels.
