Caveat medicus: consequences of federal investigations of marketing activities of pharmaceutical suppliers of prostate cancer drugs.

In the course of recent health care fraud investigations against TAP Pharmaceuticals (Lake Forest, IL) and AstraZeneca International (London, United Kingdom), each pled guilty to one violation of the Prescription Drug Marketing Act, settled claims related to alleged violations of the False Claims Act without admitting guilt, and paid fines, settlements for liabilities, and reimbursements of dollar 850 million and dollar 355 million, respectively. In a unique aspect of these cases, federal investigators brought criminal charges against 14 TAP employees and investigated the billing practices of several urologists. These investigations resulted in guilty pleas from both urologists and industry employees relative to the Prescription Drug Marketing Act or the False Claims Act and probationary sentences with payments of fines and restitution to the government for urologists who cooperated with federal investigations.
