Washington ? Federal prosecutors hit Pfizer Inc. with a record-breaking $2.3 billion in fines Wednesday and called the world’s largest drugmaker a repeating corporate cheat for illegal drug promotions that plied doctors with free golf, massages, and resort junkets.

Announcing the penalty as a warning to all drug manufacturers, Justice Department officials said the overall settlement is the largest ever paid by a drug company for alleged violations of federal drug rules, and the $1.2 billion criminal fine is the largest ever in any U.S. criminal case. The total includes $1 billion in civil penalties and a $100 million criminal forfeiture.

Authorities called Pfizer a repeat offender, noting it is the company’s fourth such settlement of government charges in the last decade. The allegations surround the marketing of 13 different drugs, including big sellers such as Viagra, Zoloft, and Lipitor.

As part of its illegal marketing, Pfizer invited doctors to consultant meetings at resort locations, paying their expenses and providing perks, prosecutors said.

“They were entertained with golf, massages, and other activities,” said Mike Loucks, the U.S. attorney in Massachusetts.

Loucks said that even as Pfizer was negotiating deals on past misconduct, they were continuing to violate the very same laws with other drugs.

To prevent backsliding this time, Pfizer’s conduct will be specially monitored by the Health and Human Service Department inspector general for five years.

The settlement ends an investigation that also resulted in guilty pleas from two former Pfizer sales managers.

Officials said the U.S. industry has paid out more than $11 billion in such settlements over the past decade, but one consumer advocate voiced hope that Wednesday’s penalty was so big it would curb the abuses.

“There’s so much money in selling pills, that there’s a tremendous temptation to cheat,” said Bill Vaughan, an analyst at Consumers Union, the nonprofit publisher of Consumer Reports. “This penalty is so huge I think consumers can have some hope that maybe these guys will tighten up and run a better ship.”
