Drug Price Competition Act of 2009 - Amends the Federal Food, Drug, and Cosmetic Act to expand the definition of "first applicant" under such Act to allow a generic drug manufacturer that is currently considered an applicant subsequent to a brand-name manufacturer's 180-day exclusivity period to qualify as a first applicant for purposes of filing an abbreviated application for a new drug. Requires such applicant to submit a substantially complete application that contains and lawfully maintains a certification for such drug.
