What is Gabapentin?
Gabapentin, available under the name Neurontin is an anticonvulsant and analgesic used for neuropathic pain. Gabapentin was approved in 1993 and initially used as a muscle relaxer before being redesigned as an analgesic and an anticonvulsant. Currently, it is a Schedule V medication and has a controlled status. While the chemical structure of Gabapentin is similar to GABA, the medication has no activity at the GABA-A or GABA-B carriers of the brain.
Mechanism of Action
The exact mechanism of Gabapentin is under evaluation. But studies have shown that it interacts in a high-affinity binding site in brain membranes like the voltage-sensitive Ca2+ channels that regulate cell excitability, gene transcription, and synaptic transmission. Invitro Gabapentin modulates the action of GABA synthetic enzyme, GAD, glutamate synthesizing enzyme, and branched-chain amino acid transaminase to prevent neuronal pain transmission.
