| Quinidine Sulfate Dihydrate | antiarrhythmic, antimalarialQuinidine sulfate is the prototype of antiarrhythmicdrugs and a class IA antiarrhythmic agent according to theVaughan Williams classification. It reduces Na+ current bybinding the open ion channels (i.e., state A). The decreasedNa+entry into the myocardial cell depresses phase 4 diastolicdepolarization and shifts the intracellular threshold potentialtoward zero. These combined actions diminish thespontaneous frequency of pacemaker tissues, depress theautomaticity of ectopic foci, and, to a lesser extent, reduceimpulse formation in the SA node. This last action results inbradycardia. During the spike action potential, quinidinesulfate decreases transmembrane permeability to passiveinflux of Na+, thus slowing the process of phase 0 depolarization,which decreases conduction velocity. This is shownas a prolongation of the QRS complex of electrocardiograms.Quinidine sulfate also prolongs action potential duration,which results in a proportionate increase in the QTinterval. It is used to treat supraventricular and ventricularectopic arrhythmias, such as atrial and ventricular prematurebeats, atrial and ventricular tachycardia, atrial flutter, andatrial fibrillation.

| Quinidine | Quinidine occurs in cinchona bark to about0.25-0.3% and also in cuprea bark. It is present in quinine sulfate mother liquor. Itis formed by isomerization of quinine. Itis used in the prevention of certain cardiacarrhythmias.Primary indications for the use of quinidine include (1) abolition of premature complexes that have an atrial, A-V junctional, or ventricular origin; (2) restoration of normal sinus rhythm in atrial flutter and atrial fibrillation after controlling the ventricular rate with digitalis; (3) maintenance of normal sinus rhythm after electrical conversion of atrial arrhythmias; (4) prophylaxis against arrhythmias associated with electrical countershock; (5) termination of ventricular tachycardia; and (6) suppression of repetitive tachycardia associated with Wolff- Parkinson-White (WPW) syndrome. Although quinidine often is successful in producing normal sinus rhythm, its administration in the presence of a rapid atrial rate (flutter and possibly atrial fibrillation) can lead to a further and dangerous increase in the ventricular rate secondary to inhibition of basal vagal tone upon the A-V node. For this reason, digitalis should be used before quinidine when one is attempting to convert atrial flutter or atrial fibrillation to normal sinus rhythm. Group: Heterocyclic organic compound. Alternative Names: (8R,9S)-6'-Methoxycinchonan-9-ol. CAS No. 56-54-2. Molecular formula: C20H24N2O2. Mole weight: 324.4. Appearanc | |
