Not waiting for FDA approval is Cambridge Chemists, a drugstore on New York City’s East Side. Pharmacists there make a liquid version of minoxidil for patients of about 20 area physicians, including Dr. Reed. The pharmacy crushes prescription tablets of Loniten (the form in which Upjohn sells the drug for severe high blood pressure), mixes them with an alcohol-based solution and sells them a one-month supply of two ounces for about $75.
