Aniracetam, also known as N-anisoyl-2-pyrrolidinone, together with piracetam and nefiracetam, belong to the same class of piracetam metabolized drugs of brain cells. It is a non-NMDA receptor agent useful for the treatment of cognitive impairment. These drugs can enhance the activity of synaptic neurons phospholipase, increase the ATP formation and transport in brain, increase protein synthesis and RNA, promote the usage of brain on amino acids, phospholipids, glucose and oxygen, increase the patient's response, excitability and memory. Aniracetam has a higher effect than piracetam, but with a relatively minor side effect. It is well tolerated and efficacious in improving velocity and accuracy of the saccades, complex reaction time, and other aspects of performance.
