MedKoo CAT#: 329454

CAS#: 88069-49-2 (HCl)

Description: Pilsicainide, also known as SUN 1165, is a drug used clinically in Japan to treat cardiac arrhythmias. It functions by blocking the fast inward movement of sodium ions through the Nav1.5 sodium channel that contributes to the rapid depolarization characteristic of phase 0 in the cardiac action potential. Pilsicainide is a pure sodium channel blocker, meaning it does not significantly affect any other cardiac channels including potassium and calcium channels.
