Prescription drug samples: Does this marketing strategy counteract policies for quality use of medicines?

Prescription drug samples, as used by the pharmaceutical industry to market their products, are of current interest because of their influence on prescribing, and their potential impact on consumer safety. Very little research has been conducted into the use and misuse of prescription drug samples, and the influence of samples on health policies designed to improve the rational use of medicines. This is a topical issue in the prescription drug debate, with increasing costs and increasing concerns about optimizing use of medicines. This manuscript critically evaluates the research that has been conducted to date about prescription drug samples, discusses the issues raised in the context of traditional marketing theory, and suggests possible alternatives for the future.

Which drug combination for hormone-refractory prostate cancer

Patients with metastatic hormone-refractory prostate cancer have a progressive disease with a median survival of similar to 11 months, and currently no treatment offers a survival advantage. The standard drug treatment is a corticosteroid and chemotherapy with mitoxantrone. In a comparison of docetaxel every 3 weeks and prednisone, versus mitoxantrone and prednisone, with a follow-up of similar to 21 months, there were less deaths in the docetaxel group than in the mitoxantrone group (166 of 335 patients and 201 of 337 patients, respectively). Docetaxel also prolonged the duration of survival compared with mitoxantrone (18.9 and 16.5 months, respectively). When given with prednisone, docetaxel was also shown to reduce pain and serum prostate specific antigen levels and improve quality of life compared with mitoxantrone/prednisone. In another trial in hormone-resistant prostate cancer patients, which compared docetaxel and estramustine with mitoxantrone and prednisone during a median follow-up of 32 months, there were fewer deaths with docetaxel/estramustine than with mitoxantrone/prednisone, which were 217 of 338 and 235 of 336 patients, respectively. Median survival was also longer in the docetaxel and estramustine group than in the mitoxantrone/prednisone group (17.5 and 15.6 months, respectively). In conclusion, two combinations (docetaxel/prednisone and docetaxel/estramustine) have been shown to be superior to mitoxantrone/prednisone in hormone-refractory prostate cancer and both should be considered for use. With the present information, there is little to distinguish between these combinations.

Reflections on the development and implementation of an early warning system for ecstasy and related drug markets in Australia

Regular and systematic monitoring of drug markets provides the basis for evidence-based policy. In Australia, trends in ecstasy and related drug (ERD) markets have been monitored in selected jurisdictions since 2000 and nationally since 2003, by the Party Drugs Initiative (PDI). The PDI maximises the validity of conclusions by triangulating information from (a) interviews with regular ecstasy users (REU), (b) interviews with key experts and (c) indicator data. There is currently no other system in Australia for monitoring these markets systematically; however, the value of the PDI has been constrained by the quality of available data. Difficulties in recruiting and interviewing appropriate consumers (REU) and key experts have been experienced, but largely overcome. Limitations of available indicator data from both health and law enforcement continue to present challenges and there remains considerable scope for enhancing existing routine data collection systems, to facilitate monitoring of ERD markets. With an expanding market for ecstasy and related drugs in Australia, and in the context of indicator data that continue to be limited in scope and detail, there is a strong argument for the continued collection of annual, comparable data from a sentinel group of REU, such as those recruited for the PDI.
