Gabapentin

Brand Names: Neurontin, Gralise, Horizant, Fanatrex.

Definition: Gabapentin is a gabapentinoid medication primarily used to treat neuropathic pain and as an anticonvulsant for the treatment of partial seizures. While its structure is similar to the neurotransmitter gamma-aminobutyric acid (GABA), it does not bind to GABA receptors; instead, it works by affecting the way nerves send messages to the brain. It is commonly prescribed for conditions such as postherpetic neuralgia (nerve pain following shingles) and restless legs syndrome.
