Description
Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/1338053 | https://www.ncbi.nlm.nih.gov/pubmed/12070527 | https://drug.mynahcare.com/drugs/genericdetail/aniracetam-MTQz

Aniracetam is a nootropic drug. It behaves as a positive modulator of AMPA-sensitive glutamate receptors. Aniracetam is clinically used in patients with mild to moderate senile dementia of the Alzheimer type. In Japan, the drug was prescribed for eight years to treat emotional disturbances, such as depressed mood and anxiety/agitation, but not memory impairment following cerebral infarction. Aniracetam (Draganon®) has been withdrawn from the Japanese market because of the unexpected failure in the latest placebo-controlled double-blind study. Animal studies demonstrated that aniracetam has clinical potential in personality disorders, anxiety, depression, posttraumatic stress disorder, attention-deficit/hyperactivity disorder, autism, negative symptoms of schizophrenia, and sleep disorders.

Approved Use

Results from trials in elderly patients with mild to moderate cognitive impairment due to senile dementia of the Alzheimer type suggest that aniracetam may be of benefit, with further trials required to confirm its efficacy profile and to define more precisely those patients most likely to respond to treatment
