Pharmaceutical marketing: the example of drug samples.

Branded drug samples are one of the most important promotional tools that pharmaceutical manufactures employ. Pharmaceutical sales representatives ("drug reps") use samples to gain access to physicians and other prescribers. Sample provision is closely intertwined with visits by drug reps; detailing visits convince physicians to try new products, while sampling maintains the flow of prescriptions. Only drugs with the highest profit margins are sampled. Although physicians believe that samples save patients money, patients who receive samples have higher overall out-of-pocket costs. Most studies have found that patients in financial need are least likely to receive samples. Pharmaceutical marketers pitch samples as a low-risk way to deal with diagnostic uncertainty. In fact, there is no evidence that samples aid diagnosis. Sample availability may compromise patient safety by reducing compliance with guidelines and steering patients towards newer drugs, for which adverse effects have not been well-delineated. Although physicians believe that samples improve adherence for low-income patients, branded samples do not improve access or adherence Samples are not a charitable activity, but are instead a highly effective form of drug marketing. Sampling of branded drugs increase drug costs for everyone. Only a cohesive effort by clinicians, legislators and policymakers can end this practice. Evidence supports a ban on sample distribution of branded products.
