What is Quinidex
QuinidineThe Generic name of this drug
Treatment SummaryQuinidine is an alkaloid derived from the bark of the Cinchona tree. It is an optical isomer of quinine. The drug works by blocking sodium and potassium currents in the body, which helps to reduce the excitability of muscles, making them less active. It also blocks certain nerve signals, preventing them from reaching their targets.

Effectiveness
How Quinidex Affects PatientsQuinidine is a drug used to treat irregular heart rhythms, such as atrial flutter, atrial fibrillation, and paroxysmal supraventricular tachycardia. It can increase the rate of your heartbeat, and may also cause a prolongation of the QT interval. This could lead to a type of dangerous irregular heart rhythm called _torsades de pointes_. You are at greater risk of this if you have a slow heartbeat, low potassium or magnesium levels, or if you have high levels of quinidine in your system. It may also increase the rate of your heartbeat if you have atrial
How Quinidex works in the bodyQuinidine works to treat arrhythmias by blocking sodium channels in the heart muscles. This prevents the rapid depolarization of the heart's action potential. Quinidine also reduces the flow of potassium and calcium in the heart, which lengthens the action potential and increases the chances of early afterdepolarization. Additionally, quinidine is used to treat malaria, as it acts as a parasite killer within red blood cells.

Quinidex Toxicity & Overdose RiskTaking too much quinidine can be very dangerous. In some cases, it has even been fatal. A child once died after taking 5 grams of quinidine, while another person survived after taking 8 grams. Taking too much quinidine can also cause the stomach to form a hard blockage called a bezoar, which can lead to higher levels of the drug in the body. Other signs of quinidine overdose include irregular heartbeats, low blood pressure, vomiting, ringing in the ears, vision problems, headaches, confusion, and delirium.

2/23/2009 This treatment has been keeping me alive and well since 1989.
2.3Patient Review
8/31/2011 I experienced severe joint stiffness for six months before learning that my quinidine medications were the root cause. I'm thankful to Dr. Frank C. Arnett of Houston for diagnosing the problem. This is a rare side effect, but it's one that should definitely be noted by patients and doctors alike.
