(±)-Pirmenol is primarily used in medical and pharmacological research as an antiarrhythmic agent. It is studied for its potential to treat cardiac arrhythmias by stabilizing the heart's electrical activity. This chemical acts by blocking sodium channels in cardiac cells, which helps to regulate irregular heartbeats. Its application is significant in developing treatments for conditions like atrial fibrillation and ventricular tachycardia. Researchers also explore its efficacy and safety profile to determine its suitability for clinical use in managing heart rhythm disorders.
