Minoxidil is a pyrimidine derivative originally developed as an oral antihypertensive agent. It is now widely used in topical formulations to treat androgenetic alopecia and other forms of hair loss. Minoxidil acts as a potassium channel opener, leading to vasodilation and improved blood flow to hair follicles, thereby stimulating hair growth. The CAS number 83701-22-8 refers to Minoxidil sulfate, the active metabolite of Minoxidil, which is formed in the body and is also involved in promoting hair growth.
