Quinidine is a pharmaceutical agent that acts as a class I antiarrhythmic agent (Ia) in the heart.It is a stereoisomer of quinine, originally derived from the bark of the cinchona tree. The drug causes increased action potential duration, as well as a prolonged QT interval.
Quinidine is used as a class I antiarrhythmic agent, that is, to prevent ventricular arrhythmias It is also used to maintain s
This medication is used to treat or prevent many types of irregular heartbeats (heart arrhythmias such as atrial fibrillation). Quinidine can greatly improve your ability to perform normal activities by decreasing the number of irregular heartbeats you have. However, it may not stop all your irregular heartbeats completely. It works by blocking abnormal heartbeat signals.
Before and while you are using quinidine, your doctor may prescribe other medications (e.g., "blood thinners"/anticoagulants such as warfarin, beta blockers such as metoprolol) to shrink any blood clots in the heart and to slow your pulse.
An optical isomer of quinine, extracted from the bark of the Cinchona tree and similar plant species. This alkaloid dampens the excitability of cardiac and skeletal muscles by blocking sodium and potassium currents across cellular membranes. It prolongs cellular action potential, and decreases automaticity.
Quinidine also blocks muscarinic and alpha-adrenergic neurotransmission.
Quinidine is an antiarrhythmic drug used in the treatment of abnormal heart rhythms such as atrial fibrillation, atrial flutter, and ventricular arrhythmias such as paroxysmal ventricular tachycardia.
Quinidine also is used to treat malaria.
