Advanced Science, Volume 13, Issue 20, 9 April 2026.The ultra‐short‐acting sedative remimazolam has a sustained therapeutic effect on the core symptoms of VPA‐exposed mice. Remimazolam, a GABA agonist, exerts its therapeutic effects by protecting dopamine neurons in the VTA of VPA‐exposed mice. Meanwhile, ferroptosis is the critical mechanism by which remimazolam protects VTA dopaminergic neurons and ...
