Fasoracetam (also known as NS-105) is a potent nootropic compound belonging to the racetam family. Unlike many other racetams that primarily target memory enhancement, fasoracetam is known for its anxiolytic (anti-anxiety) and focus-enhancing properties, combined with cognitive support.
Fasoracetam is one of the few racetams that acts as a GABA-B receptor antagonist. This unique mechanism reduces anxiety and improves focus without sedation—unlike traditional anxiolytics (benzodiazepines) which cause drowsiness.

Fasoracetam | NS-105
Fasoracetam was developed in the early 1990s. Scientists from the Japanese pharmaceutical company Nippon Shinyaku. They were looking for an effective remedy that could be used in treatments for Alzheimer’s disease. However, further studies have shown that it is a preparation that can also be successfully used in the treatment of ADHD or dementia, as well as improving memory and cognitive abilities in healthy people.
Racetam Family Comparison:
| Compound | Primary Mechanism | Anxiolytic Effect | Focus Effect | Memory Effect |
|---|---|---|---|---|
| Fasoracetam | GABA-B antagonist | Strong | Strong | Moderate |
| Piracetam | AMPA modulation | Minimal | Mild | Moderate |
| Aniracetam | AMPA + GABA-A | Moderate | Mild | Strong |
| Pramiracetam | HACU enhancement | Minimal | Mild | Very Strong |
| Phenylpiracetam | AMPA + dopamine | Mild | Strong | Moderate |
Synonym: NS-105
Most racetams work through AMPA/glutamate pathways. Fasoracetam’s GABA-B antagonism is unique among nootropics. By blocking inhibitory GABA-B receptors, it reduces excessive neural inhibition—improving focus and reducing anxiety without the sedation of benzodiazepines.
