detailer
n.— «The sale of prescription data, in which individual patients’ identities have been removed, has become a lucrative industry. The information is purchased from pharmacy chains and the companies that manage drug benefits for employers. Sales representatives—known as detailers in industry argot—often visit doctors’ offices carrying laptop computers with detailed reports on each doctor’s prescription-writing habits.» —“Federal Court Upholds Drug Privacy Law” by Stephanie Saul New York Times Nov. 18, 2008.
