The maker of the drug Plavix pleaded guilty to making false statements to federal regulators Monday and paid a $1million fine.

Bristol-Myers Squibb was trying to keep a rival company from producing a cheaper, generic version of the blood-thinner, Plavix.

Federal officials said the company failed to tell regulators about a collapsed agreement to keep the generic drug off the market.

Bristol-Myers was eager to block competition from the rival company because it was selling billions of dollars worth of Plavix.
