Pfizer (PFE 0.55%)'s pipeline has been the subject of much speculation (and some derision) lately as the company has been spotlighted in its attempts to juice growth by purchasing British pharma AstraZeneca. But there are exciting opportunities in Pfizer's pipeline -- for example: Bococizumab, the PCSK9 inhibitor that has lots of investors excited. Even so, there is one drug that really seems to stand out as perhaps the most exciting opportunity in Pfizer's pipeline: Breast cancer drug palbociclib, which was recently submitted for FDA approval.

And in the video below, from Where The Money Is, the Motley Fool's investing show, health care analysts Michael Douglass and David Williamson lay out the potential opportunity for palbociclib and why investors are so excited about the drug.
