The mechanism behind this action is unclear however, [11] with some researchers suggesting that FQs may act as low-affinity GABA-A antagonists, [12] and others positing that its interactions with N-methyl-D-aspartate (NMDA) receptors, which have been associated with fear, anxiety, and depression, may be responsible for the anxiogenic effects.
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]
[1] [2] The effects of GABA A receptor NAMs are functionally the opposite of those of GABA A receptor positive allosteric modulators (PAMs) like the benzodiazepines, barbiturates, and ethanol . [1] [2] Non-selective GABA A receptor NAMs can produce a variety of effects including convulsions, neurotoxicity, and anxiety, among others. [1] [2]
SSRIs are generally less likely to cause side effects than older antidepressants, but adverse effects still happen for some people. Common SSRI side effects include nausea, agitation, anxiety ...
SSRIs are used in all types of anxiety disorders while SNRIs are used for generalized anxiety disorder (GAD). Both of them are considered as first-line anti-anxiety medications. TCAs are second-line treatment as they cause more significant adverse effects when compared to the first-line treatment.
The subset of GABA A receptors that also bind benzodiazepines are referred to as benzodiazepine receptors (BzR). The GABA A receptor is a heteromer composed of five subunits, the most common ones being two αs, two βs, and one γ (α 2 β 2 γ1). For each subunit, many subtypes exist (α 1–6, β 1–3, and γ 1–3).
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 ...
This interaction seems to be critical for increased availability of norepinephrine in or near the synaptic clefts. Actions of imipramine-like tricyclic antidepressants have complex, secondary adaptions to their initial and sustained actions as inhibitors of norepinephrine transport and variable blockade of serotonin transport.
