To treat osteoporosis, doctors usually recommend calcium supplements, hormones, and most likely a medication to halt bone loss. In fact, they order the bone-loss drugs with such frequency that the most commonly prescribed medication, Fosamax, netted whopping sales of $3 billion in 2007. And those revenues tell just part of the story. Fosamax belongs to a class of drugs called bisphosphanates, which brought in $6.2 billion in 2004, with over 10 million users and a projected annual growth rate of almost seven percent.
