The pharmaceutical industry is one of the most profitable, both in America and around the world. But recently in the US, fines for malfeasance have stained its image. We speak with Dr. Peter Rost, who worked inside the pharmaceutical industry for decades. He was a vice president at Pfizer when he saw first-hand how pharmaceutical marketing can cross the line. After he blew the whistle on illegal marketing practices, Dr. Rost lost his job in the drug industry. We discuss his memoir, Whistleblower: Confessions of a Health Care Hitman, and get his critical perspective on the business of prescription drugs. Guest: Peter Rost, MD, former vice-president of Pfizer. Author of Whistleblower: Confessions of a Health Care Hitman and a novel, Killer Drug. His blog is: http://peterrost.blogspot.com/
