What are Class 1C drugs primarily used for?

Class 1C drugs are primarily used as antiarrhythmics. They work by blocking sodium channels in cardiac cells, which helps to suppress abnormal electrical activity in the heart and restore normal rhythm. This makes them effective in treating various types of arrhythmias, such as atrial fibrillation and ventricular tachycardia.

The specificity of Class 1C drugs lies in their ability to affect the conduction velocity in the heart without significantly altering the action potential duration, making them particularly useful in managing conditions characterized by rapid heart rhythms. Understanding the role of these medications is crucial for health fitness specialists, as they often work with clients who may have cardiovascular conditions that require careful monitoring of heart rhythm and function.
