Mechanism of action

Pregabalin is a gabapentinoid that decreases calcium influx into nerve terminals by binding to the alpha-2-delta-1 subunit of presynaptic voltage-gated calcium channels. This reduces the release of neurotransmitters such as glutamate, noradrenaline, and substance P, thereby dampening neuronal hyperexcitability. As add-on therapy, it enhances the efficacy of other treatments in conditions characterized by neuropathic pain or seizure activity.
