This is from back in April.
Feds found Pfizer too big to nail
Pfizer was caught selling Bextra, a drug not allowed to be sold because of health concerns. They continued to sell it, making $1.7 billion. They got caught.
What should have happened is that Pfizer should have been no longer qualified to sell the drugs in the Medicaid/Medicare program - which would have been a death sentence to the company.
However, Pfizer used a subsidiary, Pharmacia & Upjohn Co. Inc., to take the court judgment for Pfizer. The result is that Pharmacia & Upjohn is now excluded from Medicaid & Medicare accounts - but Pfizer, who committed the crime, remains intact, dealing drugs freely with Medicaid and Medicare patients.
As I have said before - it's not deregulation, it's lack of enforcement.
