Minoxidil

Minoxidil is an antihypertensive vasodilator medication which also slows or stops hair loss and promotes hair regrowth. Now off-patent, it is available over-the-counter for the treatment of androgenic alopecia. Minoxidil must be used indefinitely for continued support of existing hair follicles and the maintenance of any experienced hair regrowth. It is marketed under many trade names, including Avacor Physician's Formulation, Loniten (oral), Mintop, Amexidil, Rogaine, Spectral.DNC, and Vanarex. Kopexil is a derivative of minoxidil missing the piperidine substituent.
