  2. Vigabatrin - Wikipedia

    en.wikipedia.org/wiki/Vigabatrin

    Vigabatrin is an irreversible mechanism-based inhibitor of gamma-aminobutyric acid aminotransferase (GABA-AT), the enzyme responsible for the catabolism of GABA. Inhibition of GABA-AT results in increased levels of GABA in the brain. [7] [26] Vigabatrin is a racemic compound, and its [S]-enantiomer is pharmacologically active. [27], [28]

  3. Gabapentin - Wikipedia

    en.wikipedia.org/wiki/Gabapentin

    The oral bioavailability of gabapentin is approximately 80% at 100 mg administered three times daily once every 8 hours, but decreases to 60% at 300 mg, 47% at 400 mg, 34% at 800 mg, 33% at 1,200 mg, and 27% at 1,600 mg, all with the same dosing schedule.

  4. GABA reuptake inhibitor - Wikipedia

    en.wikipedia.org/wiki/GABA_reuptake_inhibitor

    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]

  5. Gabapentinoid - Wikipedia

    en.wikipedia.org/wiki/Gabapentinoid

    The gabapentinoids are 3-substituted derivatives of GABA; hence, they are GABA analogues, as well as γ-amino acids. [ 3 ] [ 4 ] Specifically, pregabalin is ( S )-(+)-3-isobutyl-GABA, phenibut is 3-phenyl-GABA, [ 28 ] and gabapentin is a derivative of GABA with a cyclohexane ring at the 3 position (or, somewhat inappropriately named, 3 ...

  6. GABA receptor agonist - Wikipedia

    en.wikipedia.org/wiki/GABA_receptor_agonist

    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 ...

  7. γ-Amino-β-hydroxybutyric acid - Wikipedia

    en.wikipedia.org/wiki/Γ-amino-β-hydroxybutyric...

    GABOB is a GABA receptor agonist. [6] It has two stereoisomers, and shows stereoselectivity in its actions. [6] Specifically, (R)-(–)-GABOB is a moderate-potency agonist of the GABA B receptor, while (S)-(+)-GABOB is a partial agonist of the GABA B receptor and an agonist of the GABA A receptor. [6]

  8. Glutamate–glutamine cycle - Wikipedia

    en.wikipedia.org/wiki/Glutamate–glutamine_cycle

    The glutamate/GABA–glutamine cycle is a metabolic pathway that describes the release of either glutamate or GABA from neurons which is then taken up into astrocytes (non-neuronal glial cells). In return, astrocytes release glutamine to be taken up into neurons for use as a precursor to the synthesis of either glutamate or GABA.

  9. GABA receptor antagonist - Wikipedia

    en.wikipedia.org/wiki/GABA_receptor_antagonist

    GABA receptor antagonists are drugs that inhibit the action of GABA. In general these drugs produce stimulant and convulsant effects, and are mainly used for ...
