Talk:Minoxidil

From Wikipedia, the free encyclopedia

the current entry says that it is unknown how minoxidil stimulates hair growth, but i don't believe that is accurate. my understanding is that it dialates blood vessels, increasing blood flow to the area. (that's why it was originally thought of as a heart attack/blood pressure medicine, because it would dialate blood vessels, increasing blood flow)

yes and...it's exat mechanism of action is not...known.

ok, well we're kind of splitting hairs -- The article says "It is unknown how the drug stimulates hair growth." Known is that it stimulates hair growth by dialating blood vessels which increases blood flow to the area. What is unknown is exactly how it dialates blood vessels.

it opens atp sensitive k+ channels causing hyperpolarisation which opens ca2+ channels and this causes vasodilation and falling TPR
