What is gabapentin, and how does it work (mechanism of action)
Doctors do not know how gabapentin works (the mechanism of action). Gabapentin structurally resembles the neurotransmitter gamma aminobutyric acid (GABA). (Neurotransmitters are drugs that nerves use to communicate with one another.) It is possible that this similarity is related to gabapentin's mechanism of action. In animal models used for testing the anticonvulsant and analgesic (anti-pain) activities of drugs, gabapentin prevents seizures and reduces pain-related responses.
