Another drug stock that I really like is Endo Pharmaceuticals (ENDP). Endo Pharmaceuticals is a midcap biotechnology company that is know for developing and selling pain management drugs and therapies.

Endo also has a strong drug development division along with established money makers Percocet, Percodan and Endocent
