What are the public health effects of direct-to-consumer drug advertising?

BACKGROUND TO THE DEBATE: Only two industrialized countries, the United States and New Zealand, allow direct-to-consumer advertising (DTCA) of prescription medicines, although New Zealand is planning a ban. The challenge for these governments is ensuring that DTCA is more beneficial than harmful. Proponents of DTCA argue that it helps to inform the public about available treatments and stimulates appropriate use of drugs for high-priority illnesses (such as statin use in people with ischemic heart disease). Critics argue that the information in the adverts is often biased and misleading, and that DTCA raises prescribing costs without net evidence of health benefits.

Banning all drug promotion is the best option pending major reforms.

Drug promotion should be evaluated according to its impact on health, access to information, informed consent, and wealth. Drug promotion currently does more harm than good to each of these objectives because it is usually misleading. This is a systemic problem. Whilst improved regulation and education will address it to some degree, major reforms to payment systems for drug companies and doctors are also required. Until all these systemic reforms can be put in place, the best policy option is to ban the promotion of drugs to doctors and the public. Consequently, pending major reforms, it is appropriate for governments to restrict drug promotion as much as is politically achievable.

Management of hyperlipidaemia.

BACKGROUND: Hyperlipidaemia is a general term for elevated concentrations of any or all lipids in the plasma. An elevated cholesterol is one of several risk factors for coronary heart disease (CHD). In Australia, the use of cholesterol lowering drugs, mainly statins, consumes over 880 million dollars or 16% of the Pharmaceutical Benefits Scheme drug budget and is growing. OBJECTIVE: This article focuses on primary hypercholesterolaemia, its relationship with CHD, and its management in the community setting. DISCUSSION: There is strong evidence that treating middle aged men with statins who have established CHD will reduce overall mortality, CHD morbidity, or mortality and stroke. There is weaker but reasonable evidence for treating men aged over 65 years and women of any age who have CHD, or people without CHD but at high risk. There may be some benefits for patients with stroke and peripheral vascular disease who are at risk of CHD. While discontinuation rates are high, the occurrence of serious adverse reactions are infrequent.

The ethics of pharmaceutical industry relationships with medical students.

Little research has been done on the extent of the relationship between the pharmaceutical industry and medical students, and the effect on students of receiving gifts. Potential harms to patients are documented elsewhere; we focus on potential harms to students. Students who receive gifts may believe that they are receiving something for nothing, contributing to a sense of entitlement that is not in the best interests of their moral development as doctors. Alternatively, students may be subject to recognised or unrecognised reciprocal obligations that potentially influence their decision making. Medical educators have a duty of care to protect students from influence by pharmaceutical companies.
