Used primarily in the management of mild to moderate hypertension, rescinnamine helps lower blood pressure by promoting the depletion of catecholamines such as norepinephrine from nerve terminals. This action results in reduced peripheral vascular resistance and a slower heart rate, contributing to its antihypertensive effect. It is valued for its relatively mild side effect profile compared to other agents in its class, making it suitable for long-term therapy in select patients. Additionally, rescinnamine has been studied for its potential in modulating sympathetic nervous system activity, which may offer benefits in certain cardiovascular conditions.
