Quinidine methiodide is a quaternized derivative of quinidine and a classical ion channel blocker. Unable to penetrate the blood-brain barrier, it prolongs action potential duration by exclusively blocking voltage-gated sodium and potassium channels on peripheral membranes, acting as a benchmark tool in neuromuscular and cardiovascular electrophysiology research.
