Kopexil (INCI name diaminopyrimidine oxide, trade name Aminexil) is a chemical compound similar to minoxidil. Minoxidil was originally used to treat high blood pressure; a side effect was increased body hair. Both compounds have been used for therapy of alopecia.[2] Kopexil is not approved for use as a drug in the United States or in Europe.
