Minoxidil, known as 6 - (1-piperidinyl) - 2,4-pyrimidine diamine-3-oxide, is an organic compound with white or almost white crystalline powder. It can relax the smooth muscle of blood vessel directly, and has strong effect of small artery dilation. It is used for intractable, primary or renal hypertension. It is used to prevent fat hair loss and animal husbandry.

Minoxidil, known as 6 - (1-piperidinyl) - 2,4-pyrimidine diamine-3-oxide, is an organic compound with white or almost white crystalline powder. Clinically, as a potassium channel opener, it can directly relax vascular smooth muscle, has a strong effect of small artery dilation, reduces peripheral resistance and blood pressure, and has no effect on volume vessels, so it can promote venous reflux. At the same time, due to reflex regulation and positive frequency effect, cardiac output and heart rate increased, but postural hypotension did not occur.

Minoxidil in the treatment of hypertension found that it can make hair (beard) longer, thicker. Therefore, it has been developed and applied as a drug for the treatment of male alopecia. It has been reported that it also has a certain effect on the treatment of alopecia areata.
