Aniracetam (brand names Draganon, Sarpul, Ampamet, Memodrin, Referan), also known as N-anisoyl-2-pyrrolidinone, is a racetam which is sold in Europe as a prescription drug.

It is not approved by the Food and Drug Administration for use in the United States as a prescription medication or dietary supplement.

[2][10][11] There is some preliminary research suggesting that N-anisoyl-GABA and to a lesser degree p-ansic acid may contribute to the stimulatory effects of aniracetam in rats.

[13] For instance, a study using the forced swim test in rats found that the two metabolites 2-pyrrolidinone and N-anisoyl-GABA alone yielded similar anti-depressant effects as aniracetam itself.

[12] The authors of the aforementioned study hypothesized that the metabolites work by increasing levels of dopamine and by stimulating the nicotinic acetylcholine receptors.
