It antagonizes the vasodilatory effect of cromakalim on isolated circumflex coronary artery segments in dogs, reduces systemic vascular resistance, and increases cardiac output. It also improves erectile dysfunction and can be used in research on erectile dysfunction\u003csup\u003e[1][2][3]\u003c\/sup\u003e.
