Aminalon is the pharmaceutical preparation of gamma aminobutyric acid (GABA), which is the main inhibitory neurotransmitter in the central nervous system. Most of the anxiolytic drugs used today works by enhancing GABAergic neurotransmission.

Orally administered GABA has poor blood-brain permeability unlike its phenyl derivative Phenibut. However, GABA metabolites are able to reach the brain and produce a therapeutic effect.
