At the end of November, one of the most used cholesterol fighting drugs could get a lot cheaper for patients who rely on the medicine.

FOX's Colleen Cappon explains why in today's edition of Housecall For Health:

The patent on America's most popular drug, Lipitor, expires on November 30th, unleashing a wave of less expensive generic drugs.  The cholesterol fighting drug from Pfizer wrote its own chapter in pharmaceutical history, with 130 billion dollars in lifetime sales.  The expired patent will save patients money, because now they'll be able to buy cheaper generic versions.  Experts say the pharmaceutical industry may never see a giant like Lipitor again.
