Is there a contradiction between profit-making and medical needs? How important are emerging markets for the future of pharmaceutical companies? And what are the ethical boundaries in the relationship between medical practitioners and pharma companies? This series of four lectures brings together leading figures in the pharmaceutical industry, health and business to look at the challenges of reconciling medical ethics and business in the 21st century against a backdrop of scientific and clinical developments and the expectations of patients. This series was originally delivered as the 2009 Green Templeton Lectures entitled "Addicted to Big Pharma? Reconciling business, medical and ethical needs".
