Enhances high-affinity choline uptake (HACU) via a unique mechanism distinct from other racetams — it increases HACU even in damaged cholinergic neurons, suggesting a choline uptake enhancement rather than mere stimulation. This HACU enhancement persists even after the compound has been cleared, indicating a lasting modification of choline transporter activity. Also shows affinity for AMPA receptors.

Potently stimulates high-affinity choline uptake (HACU) in hippocampal synaptosomes, the rate-limiting step in acetylcholine synthesis. This profoundly enhances cholinergic neurotransmission without direct receptor agonism. Approximately 10-30x more potent than piracetam on a per-milligram basis. Does not significantly affect other neurotransmitter systems, making it a highly targeted cholinergic enhancer.
