Minoxidil, whose chemical name is 6-(1-piperidinyl)-2,4-pyrimidinediamine-3-oxide, is an organic substance that is white or off-white crystalline powder. Clinically, as a potassium channel opener, it can directly relax vascular smooth muscle, and has a powerful small arterial expansion effect, which reduces peripheral resistance and blood pressure without affecting the volume of blood vessels, so it can promote venous return. At the same time, due to reflex regulation and positive frequency effects, cardiac output and heart rate can be increased, but it does not cause orthostatic hypotension.
Uses: Antihypertensive drugs for intractable, primary or renal hypertension. Used to prevent oily hair loss and animal husbandry.
