Gabapentin (GBP) was originally developed as a potential agonist for Gamma-Amino-Butyric-Acid (GABA) receptors, aiming to inhibit the activation of pain-signaling neurons. Contrary to initial expectations, it does not bind to GABA receptors. This study suggested that the antiepileptic GABA analogue gabapentin (Neurontin) is an agonist at GABA(B) receptors expressing the GABA(B1a) but not the GABA(B1b) receptor subunit. GABA and gabapentin are often mistakenly used interchangeably, but they are not the same. GABA is an amino acid supplement and neurotransmitter, while gabapentin is a prescription medication. While practitioners may confuse the two, it’s important to understand their differences. 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. Gabapentin enacarbil is a prodrug of gabapentin and was designed to overcome the limitations of gabapentin (gabapentin is poorly absorbed and only lasts for a short duration of time). Liver enzymes convert gabapentin enacarbil it into its active form, gabapentin. It is concluded that gabapentin is not an agonist at GABA B receptors that are functional in baclofeninduced antiallodynia in the postoperative pain model in vivo and in GIRK channel activation in ventrolateral PAG neurons in vitro. Abstract Background. Gabapentin is a structural analog of the inhibitory neurotransmitter γ-aminobutyric acid (GABA). 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. On the other hand, Gabapentin is a medication that is structurally similar to GABA but does not directly bind to GABA receptors. Instead, it modulates the release of certain neurotransmitters, such as glutamate, to reduce nerve excitability and alleviate pain or seizures. It is concluded that gabapentin is not an agonist at GABA (B) receptors that are functional in baclofen-induced antiallodynia in the postoperative pain model in vivo and in GIRK Although the identification of these variants is suggestive of pharmacologically distinct GABA B receptors, Ng and colleagues reported that the anticonvulsant gabapentin acts as an agonist at GABA B(1a) but not GABA B(1b) (Bertrand et al. 2001; Ng et al. 2001), this has been widely disputed as heterodimers comprised of either GABA B(1a) /GABA 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. The α 1 subunit allows entry of calcium and the extracellular α 2 δ is bound to the γ Gabapentin is a structural analog of the inhibitory neurotransmitter γ-aminobutyric acid (GABA). 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. 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. Even though gabapentin is a structural GABA analogue, and despite its name, it does not bind to the GABA receptors, does not convert into GABA Tooltip γ-aminobutyric acid or another GABA receptor agonist in vivo, and does not modulate GABA transport or metabolism within the range of clinical dosing. [85] Results with human and rat brain NMR spectroscopy indicate that gabapentin increases GABA synthesis. Gabapentin increases non-synaptic GABA responses from neuronal tissues in vitro. In vitro, gabapentin reduces the release of several mono-amine neurotransmitters. Although gabapentin is a GABA analogue, it does not bind to and modulate the GABA receptors nor does it affect GABA transport or metabolism. Gabapentin is a gabapentinoid, which acts as an inhibitor of the α2δ subunit-containing voltage-dependent calcium channels (VDCCs) that are linked to neurotransmitter release. Gabapentin is a structural analog of the inhibitory neurotransmitter γ-aminobutyric acid (GABA). 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 is a GABA agonist and anticonvulsant that increases GABA concentrations in the central nervous system, possibly via inhibition of GABA-transaminase (Cai et al., 2012). While more commonly trialed in combination with flumazenil, as described above, one double-blind RCT ( Heinzerling et al., 2006 ) examined gabapentin as an individual 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. Originally designed as analogs of GABA (Fig. 1), neither gabapentin nor pregabalin has any significant agonist‐like effect on GABA A or GABA B receptors, nor obvious effects on levels of GABA (Lanneau et al. 2001; Jensen et al. 2002).
