Gabapentin belongs to a class of medications called 'anticonvulsants' used to prevent neuropathic pain (pain due to damaged nerves), fibromyalgia (musculoskeletal pain), and epilepsy (fits). It works by binding to the specific site on voltage-gated calcium channels and blocking the action of overexcited channels; this helps in relieving nerve pain and lowers the risk of seizures. Overall it reduces nerve pain by interfering with pain signals travelling through the damaged nerves and the brain.
