Aniracetam (Draganon, Sarpul, Ampamet, Memodrin) is an ampakine and nootropic of the racetam chemical class purported to be considerably more potent than piracetam. It is lipid-soluble and has possible cognition-enhancing effects. It has been tested in animals extensively, Alzheimer's patients, and temporarily-impaired healthy subjects. It has shown potential as an anxiolytic in three clinical animal models. It is sold in Europe as a prescription drug.



After a confirmed test of the anxiolytic efficacy in a mouse model, haloperidol, mecamylamine, and ketanserin were applied to determine the pathways aniracetam depends on to exert its anti-anxiety effects. Haloperidol completely reversed the anxiolytic effects, and mecamylamine and ketanserin nearly completely reversed the effects. This shows that aniracetam's anxiolytic mechanism is facilitated by D2/D3, nACh, and 5-HT2A receptors.[1]

Aniracetam has also been shown to selectively modulate the AMPA receptor[2] and was used as the parent compound to derive a class of drugs known as the ampakines that are being investigated as nootropics and neuroprotective drugs for the treatment of Alzheimer's disease and other neurodegenerative conditions.1

Despite the fat solubility of aniracetam, its half-life is much shorter than that of common racetam analogs such as piracetam.[citation needed]

Commonly used doses are 750-3,000 mg daily usually taken in 2-3 doses.

Side effects can include nausea and headache.[citation needed]
