gamma-aminobutyric acid
Quick Summary
Gamma-aminobutyric acid (GABA) is an amino acid found in high concentrations in the central nervous system. It functions as an inhibitory neurotransmitter, meaning it reduces the activity of neurons. GABA is produced from glutamate by an enzyme called glutamic acid decarboxylase (GAD).1
GABA works by opening chloride channels in the postsynaptic membrane, which typically causes hyperpolarization. This process inhibits nerve activity. GABA is widely distributed throughout the brain, particularly in higher levels of the central nervous system. Its action is terminated by uptake systems that return it to the presynaptic terminal or surrounding glial cells.1

…a special site on the gamma-aminobutyric acid A (GABAA) receptor in the central nervous system. This binding action increases the receptor’s affinity to the inhibitory neurotransmitter GABA. Enhanced GABA activity reduces the transmission of neural impulses in the brain that are associated with anxiety and panic.

Benzodiazepines resemble barbiturates in their side effects: sleepiness, drowsiness, reduced alertness, and unsteadiness of gait. Though less dangerous than barbiturates, they can produce physical dependency even in moderate dosages, and the…
