Nexopamil racemate is primarily used in the field of cardiovascular research due to its calcium channel-blocking properties. It is studied for its potential to manage conditions related to abnormal heart rhythms and hypertension. Researchers explore its efficacy in reducing vascular resistance and improving blood flow, which could be beneficial in treating angina and other heart-related disorders. Additionally, it is investigated for its role in protecting heart tissues during ischemic events, making it a subject of interest in developing therapies for myocardial infarction. Its application extends to preclinical studies aimed at understanding the broader implications of calcium channel modulation in various cardiovascular diseases.
