Description and Uses
Quinidine is a stereoisomer of the antimalarial agent quinine and a class Ia antiarrhythmic agent. Quinidine blocks the voltage-gated sodium (Nav) channel Nav1.5 in a use-dependent manner. It decreases the amplitude and duration of action potentials in isolated canine ventricular myocytes. It inhibits KKr, peak INa, and late INa (IC50s = 4.5, 11, and 12 μM, respectively) and can induce torsade de pointes in isolated rabbit hearts when used at a concentration of 1 μM. Quinidine induces QT prolongation in dogs. It also binds to M2 muscarinic acetylcholine receptors (Ki = 7.5 μM for human recombinant receptors expressed in HM2-B10 cells). Formulations containing quinidine have been used in the treatment of atrial fibrillation and ventricular arrhythmias.
antiarrhythmic, antimalarial
