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]
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 counteracting overdoses of sedative drugs. Examples include bicuculline, securinine and metrazol, and the benzodiazepine GABA A receptor antagonist flumazenil.
An example of a receptor site that possesses basal activity and for which inverse agonists have been identified is the GABA A receptors.Agonists for GABA A receptors (such as muscimol) create a relaxant effect, whereas inverse agonists have agitation effects (for example, Ro15-4513) or even convulsive and anxiogenic effects (certain beta-carbolines).
A GABAergic or GABAnergic agent is any chemical that modifies the effects of GABA in the body or brain. Some different classes of GABAergic drugs include agonists, antagonists, modulators, reuptake inhibitors and enzymes. [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 ...
Vigabatrin reduced cholecystokinin tetrapeptide-induced symptoms of panic disorder, in addition to elevated cortisol and ACTH levels, in healthy volunteers. [12]Vigabatrin is also used to treat seizures in succinic semialdehyde dehydrogenase deficiency (SSADHD), which is an inborn GABA metabolism defect that causes intellectual disability, hypotonia, seizures, speech disturbance, and ataxia ...
Gabaculine is a naturally occurring neurotoxin first isolated from the bacteria Streptomyces toyacaensis, [1] which acts as a potent and irreversible GABA transaminase inhibitor, [2] [3] and also a GABA reuptake inhibitor. [4] [5] Gabaculine is also known as 3-amino-2,3-dihydrobenzoic acid hydrochloride [6] and 5-amino cyclohexa-1,3 dienyl ...
