Pregabalin is a chemical analogue of the inhibitory neurotransmitter GABA, but it does not directly bind to GABA or benzodiazepine receptors. Instead, it strongly attaches to the alpha2-delta subunit of voltage-gated calcium channels in the CNS. This binding is thought to mediate its pain-relieving and anti-seizure effects, although the complete mechanism is not fully understood.
