Executive Summary

Now it’s co-promoting what my be its own worst enemy, Merck’s Fosamax. It could thereby profit from this important new drug and, by putting together a disease management program that incorporates both drugs, make an ally out of this competitor. Included is a chart of the industry's osteoporosis deals.
