A GABA reuptake inhibitor (GRI) is a type of drug which acts as a reuptake inhibitor for the neurotransmitter gamma-Aminobutyric acid (GABA) by blocking the action of the gamma-Aminobutyric acid transporters (GATs). This in turn leads to increased extracellular concentrations of GABA and therefore an increase in GABAergic neurotransmission. [1]
Gamma-aminobutyric acid, a GABA-B receptor agonist. A GABA receptor agonist is a drug that is an agonist for one or more of the GABA receptors, producing typically sedative effects, and may also cause other effects such as anxiolytic, anticonvulsant, and muscle relaxant effects. [1] There are three receptors of the gamma-aminobutyric acid. The ...
In pharmacology, GABA A receptor positive allosteric modulators, also known as GABAkines or GABA A receptor potentiators, [1] are positive allosteric modulator (PAM) molecules that increase the activity of the GABA A receptor protein in the vertebrate central nervous system. GABA is a major inhibitory neurotransmitter in the central nervous system.
Furthermore, a study examining polymorphisms in the GABA receptor beta 2 subunit gene found an association with schizophrenia and bipolar disorder, and examined three SNPs and their effects on disease frequency and treatment dosage. [62]
Like other GABA-T inhibitors, γ-acetylenic GABA causes GABA levels in the brain to be elevated. This is due to 4-aminobutyrate transaminase being the enzyme that converts γ-aminobutyric acid to L-glutamate. Inhibiting the enzyme stops this conversion from happening.

Gaboxadol is a supra-maximal agonist at α 4 β 3 δ, low-potency agonist at α 1 β 3 γ 2, partial agonist at α 4 β 3 γ, and antagonist at ρ1 GABA A receptors. [5] [6] [7] Its affinity for extrasynaptic α 4 β 3 δ GABA A receptors is 10-fold greater than other subtypes. [8]
Among Kentucky’s taxpayer-funded rehabilitation options is a network of 15 facilities — eight for men and seven for women — created about a decade ago and known as Recovery Kentucky. It represents the state’s central drug treatment effort, admitting thousands of addicts per year.
