Minoxidil is clinically used as a potassium channel opener, which can directly relax vascular smooth muscles and has a strong arterial expansion effect, which reduces peripheral resistance and blood pressure, but has no effect on volume vessels, so it can promote venous return. At the same time, due to the effect of reflex regulation and positive frequency, cardiac output and heart rate can be increased, but it does not cause orthostatic hypotension.
