The pharmaceutical company AstraZeneca said that it had reached a $520 million agreement to settle two federal investigations and two whistle-blower lawsuits over the sale and marketing of its blockbuster psychiatric drug Seroquel.
One of the investigations related to “selected physicians who participated in clinical trials involving Seroquel,” AstraZeneca disclosed in a government filing. The other case related to off-label promotion of the drug.
As a result of aggressive marketing, Seroquel has been increasingly used for children and elderly people for indications not approved by the Food and Drug Administration. Doctors are permitted to prescribe any approved drug for off-label uses.
Seroquel was the top-selling antipsychotic drug in America. It had $17 billion in sales in the United States since 2004, according to IMS Health, a research firm.
