Clonidine Mechanism

Clonidine exerts its influence on blood pressure by acting on the central nervous system.

By understanding these intricacies, you can gain insight into how Clonidine may impact your blood pressure.

Antihypertensive Properties

One of the primary roles of Clonidine is to lower high blood pressure. It accomplishes this by targeting specific receptors in the brain, leading to reduced sympathetic nervous system activity. This, in turn, results in decreased heart rate and relaxed blood vessels, ultimately lowering blood pressure levels.

Effectiveness in Blood Pressure Control
