Description
Curator's Comment: description was created based on several sources, including: https://www.ncbi.nlm.nih.gov/pubmed/10820661 | http://adisinsight.springer.com/drugs/800001382

Nefiracetam is a cyclic derivative of gamma-aminobutyric acid (GABA). It is thought to act by normalising dysfunctional acetylcholine, GABA and possibly monoamine neurotransmitter systems, but it may also facilitate N/L-type calcium channel opening. Nefiracetam has received attention as a treatment for seizures, depression, and dementia. Nefiracetam was found to be extremely testicular toxic in both rats and dogs; it was found to significantly decrease the levels of testicular testosterone leading to atrophy and malformation of sperm.

Sample Use Guides

The recommended dosage lies between 8.721mg/kg and 29.072mg/kg in humans for treating the negative cognitive effects of seizures as well as treating severely depressed individuals
Route of Administration: Oral
In Vitro Use Guide
The effects of nefiracetam on GABA-induced chloride currents were studied with rat dorsal root ganglion neurons in primary culture using the whole-cell patch-clamp technique. The dose-response curve for GABA-induced currents was shifted by 16 uM to lower concentrations by 10 uM nefiracetam while the maximal response was reduced by 22.84 +/- 0.68%.
