| Hydroquinidine |
Hydroquinidine is a d-rotatory alkaloid derived from cinchiona bark. Hydroquinidine is a pharmaceutical agent that acts as a class I antiarrhythmic agent (Ia) in the heart. Hydroquinidine causes increased action potential duration, as well as a prolonged QT interval. Like all other class I antiarrhythmic agents, hydroquinidine primarily works by blocking the fast inward sodium current (INa). Hydroquinidine is also used for the treatment of Malaria. |
