Quinidine

Quinidine (pronounced: kwin-id-een) is a pharmaceutical agent that belongs to the class of medications known as antiarrhythmics. It is primarily used in the treatment of cardiac arrhythmias.

Etymology

The term "Quinidine" is derived from Cinchona bark, from which it is extracted. The bark is named after the Countess of Chinchón, the wife of a viceroy of Peru, who, according to legend, was cured of a fever by using the bark.

Usage

Quinidine is used to treat certain types of irregular heartbeats. It helps to maintain a normal heart rhythm by blocking certain electrical signals in the heart that can lead to an irregular heartbeat.
