Used primarily in cardiovascular research to study its effects on blood pressure and fluid balance. It acts as a vasodilator, helping to relax blood vessels and reduce hypertension. Additionally, it is employed in experiments to understand its role in natriuresis, which promotes the excretion of sodium in urine, aiding in the regulation of body fluid levels. Its application extends to investigating heart failure treatments, as it can alleviate symptoms by reducing cardiac workload and improving circulation.
