General description
Cibenzoline also called (±)-2-(2,2-diphenylcyclopropyl)-2-imidazoline succinate, is generally used in stereo combination of R(+) and S(−) forms. It also exhibits anticholinergic activity.. Cibenzoline is known to improve left ventricular diastolic dysfunction by reducing left ventricular pressure gradient.
Biochem/physiol Actions
Cibenzoline is a class IA antiarrhythmic drug. Cibenzoline (μM concentrations) blocks ATP-sensitive K channels in heart and pancreatic cells. Cibenzoline interacts with the channel pore-forming subunit of the K(ATP) channel (Kir6.2) from the cytoplasmic side. Cibenzoline also inhibits the delayed rectifier K current [I(Kr)] in sino-atrial node cells.
Cibenzoline succinate inhibits ATP-sensitive K+ channels; class IA antiarrhythmic.
