Most agents that enhance GABA A receptor (GABA A R) function have antiseizure properties due to their ability to increase inhibitory neurotransmitter tone. The evidence linking epilepsy with dysfunction of GABAergic inhibition is substantial, and has been extensively reviewed 1 - 4. On the other hand, gabapentin was created to mimic some of the effects of GABA but it does not appear to affect the same receptors in the brain. Another function of GABA is its responsibility for regulating the body’s muscle tone since it is linked to the pituitary glands which affect human growth hormone (HGH) levels. GABA does seem to lower blood pressure, which could then improve brain performance (93). And ingesting GABA isn’t unnatural. Many foods contain small quantities of the compound (99). But right now, there’s very limited evidence for using GABA to lower stress levels and increase GABA levels in your brain (94). gabapentin administration was associated with an average increase in GABA concentration of 55.7% (6.9–91.0%). Importantly, drug- induced change in GABA levels was inversely correlated to the In the present study, we examined whether gabapentin is an agonist at native GABA (B) receptors using a rat model of postoperative pain in vivo and periaqueductal gray (PAG) slices in vitro; PAG contains GABA (B) receptors, and their activation results in antinociception. Although GABA concentration changes were small both within day (average 5.6%) and between day (average 4.8%), gabapentin administration was associated with an average increase in GABA Although gabapentin does not directly modify GABA-A receptor function, it may indirectly increase tonic inhibition via enhanced expression of extrasynaptic receptors in specific brain regions including the cerebellum and hippocampus. Gabapentin has no activity at GABAA or GABAB receptors of GABA uptake carriers of brain. Gabapentin interacts with a high-affinity binding site in brain membranes, which has recently been identified as an auxiliary subunit of voltage-sensitive Ca2+ channels. Its anticonvulsant, analgesic and anxiolytic properties suggest that it increases GABAergic inhibition; however, the molecular basis for these effects is unknown as gabapentin does not directly modify GABA type A (GABA A) receptor function, nor does it modify synaptic inhibition. Gabapentin and pregabalin do not bind to GABA receptors despite their structural similarity but have a high affinity for the α2δ-1 subunit of voltage-gated calcium channels (VGCCs). 19 VGCCs are composed of multiple subunits: α 1, β, γ and α 2 δ. Gabapentin is a structural analog of the inhibitory neurotransmitter GABA, yet it has no direct effects on GABA A receptor function, nor does it increase inhibitory synaptic transmission [1, 8]. Thus, the molecular basis of gabapentin's GABAergic properties has remained enigmatic. Gabapentin was formed by the addition of a cyclohexyl group to GABA, which allowed this form of GABA to cross the blood–brain barrier. Despite its structural similarity to GABA, gabapentin does interact with GABA receptors in the CNS. Its mechanism of action is unknown, but may involve enhanced neuronal GABA synthesis. Gabapentin robustly increases cell-surface expression of δGABA A receptors and increases a tonic inhibitory conductance in neurons. This enhanced δGABA A receptor function contributes to the ataxic and anxiolytic but not antinociceptive properties of gabapentin. Findings: Gabapentin enhanced expression of GABAA receptors and increased a tonic inhibitory conductance in δ neurons. This increased expression likely contributes to GABAergic effects as gabapentin caused ataxia and anxiolysis in wild-type mice but not subunit null-mutant mice. Gabapentin, marketed for the treatment of seizures and neuropathic pain, has been shown to increase in vivo GABA concentration in the brain of both rodents and humans. Gabapentin effects on glutamate are not known. While gabapentin was designed as a GABA analogue, its GABA-like properties are not as straightforward as initially believed. The drug does not directly bind to GABA receptors or increase GABA levels in the brain. However, it may indirectly enhance GABAergic neurotransmission through its effects on calcium channels and other neuronal processes. Sprouting grains, seeds, and legumes may increase GABA content. Some studies suggest that the germination process can lead to an accumulation of GABA in sprouted products. It's important to note that the GABA content in food can be influenced by factors such as processing, cooking methods, and the specific cultivar or variety of the food. Gabapentin is a structural analog of the inhibitory neurotransmitter GABA, yet it has no direct effects on GABA A receptor function, nor does it increase inhibitory synaptic transmission [1,8]. Thus, the molecular basis of gabapentin's GABAergic properties has remained enigmatic. 5-HTP: Your body converts 5-HTP into serotonin, and serotonin can enhance GABA activity. 5-HTP is a synthetic form of tryptophan, which is found in turkey. However, tryptophan from food-based sources (like turkey, soybeans, and milk) is not thought to cross the BBB the way 5-HTP does. However, gabapentin was shown to increase expression of δGABAA receptors, inhibitory tone in the cerebellum, and brain GABA concentration in patients, 3,4 while pregabalin enabled a larger neuronal calcium influx for facilitating neurotransmission. 2 These findings substantiate a GABAergic effect of gabapentin and pregabalin.
