Nootropics

Aniracetam

Evidence: moderate_human

Mechanism of Action

Potent positive allosteric modulator of AMPA receptors with 5-10x the potency of piracetam, slowing both channel closing rate and microscopic desensitization rates. Also modulates metabotropic glutamate receptors (mGluRs), activates nicotinic acetylcholine receptors, and indirectly boosts dopaminergic and serotonergic neurotransmission, conferring anxiolytic properties.

Dosing Protocol

Standard: 750-1500 mg/day divided into 2-3 doses

Maintenance: 750 mg twice daily

Administration: oral

Timing: With fat-containing meals (fat-soluble compound; bioavailability increases significantly with dietary fat)

Duration: Cycles of 8-12 weeks on, 4 weeks off

Notes

Considered the most anxiolytic racetam. Short half-life (~1-2.5 hours) necessitates multiple daily doses. The anxiolytic effects are often noticed before cognitive enhancement. Must be taken with fat for absorption. Approved in Europe and Japan for cognitive impairment.
