Relutrigine (PRAX-562) is an orally active, long-acting sodium current inhibitor that preferentially suppresses sustained INa induced by TX-II or SCN8A N1768D mutations (IC50=141/75 nM). It reduces neuronal intrinsic excitability and may be used for anticonvulsant therapy.

| Description | Relutrigine (PRAX-562) is an orally active, long-acting sodium current inhibitor that preferentially suppresses sustained INa induced by TX-II or SCN8A N1768D mutations (IC50=141/75 nM). It reduces neuronal intrinsic excitability and may be used for anticonvulsant therapy. |
| In vitro | Relutrigine (0.001–10,000 µM) inhibits the hNaV1.6 sustained sodium channel with a persistent INa preference. Relutrigine (0.3 µM) significantly reduces intrinsic excitability in wild-type CA1 pyramidal neurons [1]. |
| In vivo | Relutrigine (0.3–40 mg/kg; oral; single dose) dose-dependently protected against maximal electroconvulsive seizure (MES)-induced tonic hindlimb seizures in male CD-1 mice [1]. |
