The cavernosal tissue is highly responsive to endothelin-1 (ET-1), and penile smooth muscle cells not only respond to but also synthesize ET-1. Considering that ET-1 is directly involved in end-organ damage in salt-sensitive forms of hypertension, we hypothesized that activation

Clonidine decreases mean arterial pressure (MAP) by acting as an α(2)-adrenergic receptor (AR) agonist in the central nervous system; it also acts on peripheral α-ARs to produce vasoconstriction. Endothelin (ET) has been shown to modulate the action of ARs. The
