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]
[6] [12] Existing evidence on the use of gabapentinoids in chronic lower back pain is limited, and demonstrates significant risk of adverse effects, without any demonstrated benefit. [13] The main side-effects include: a feeling of sleepiness and tiredness, decreased blood pressure, nausea, vomiting and also glaucomatous visual hallucinations.
Gabapentin shows substantial benefit (at least 50% pain relief or a patient global impression of change (PGIC) "very much improved") for neuropathic pain (postherpetic neuralgia or peripheral diabetic neuropathy) in 30–40% of subjects treated as compared to those treated with placebo.
Neuropathic pain has profound physiological effects on the brain which can manifest as psychological disorders. Rodent models where the social effects of chronic pain can be isolated from other factors suggest that induction of chronic pain can cause anxio-depressive symptoms and that particular circuits in the brain have a direct connection.
Serotonin–norepinephrine reuptake inhibitors (SNRIs) are a class of antidepressant medications used to treat major depressive disorder (MDD), anxiety disorders, social phobia, chronic neuropathic pain, fibromyalgia syndrome (FMS), and menopausal symptoms.
Diabetes most commonly causes damage to the long nerves that supply the feet and lower legs, causing numbness, tingling and pain (diabetic polyneuropathy). Although these symptoms may also be present, the pain and weakness of proximal diabetic neuropathy often onset more quickly and affect nerves closer to the torso. [citation needed]
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 ...
Paroxetine may produce discontinuation-related symptoms at a greater rate than other SSRIs, though qualitatively similar effects have been reported for all SSRIs. [ 183 ] [ 184 ] Discontinuation effects appear to be less for fluoxetine, perhaps owing to its long half-life and the natural tapering effect associated with its slow clearance from ...
