Selected AbstractsResults, Rhetoric, and Randomized Trials: The Case of DonepezilJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 8 2008John R. Gilstad MD Whether donepezil provides meaningful benefit to patients with Alzheimer's disease (AD) is controversial, but drug sales annually total billions of dollars. A review of data from published randomized clinical trials (RCTs) found rhetorical patterns that may encourage use of this drug. To create a reproducible observation, the sentences occurring at five specific text sites in all 18 RCTs of donepezil for AD were tabulated, as were study design, sources of financial support, and outcomes that could be compared between trials. Rhetoric in the 13 vendor-supported trials (15 publications) was strongly positive. Three early trials used the motif "efficacious (or effective) , treating , symptoms" four times. "Well-tolerated and efficacious" or an equivalent motif appeared 11 times in five RCTs. Nine RCTs referred 15 times to previously proven effectiveness. Seven trials encourage off-label use, for "early" cognitive impairment, severe dementia in advance of the Food and Drug Administration labeling change, or behavioral symptoms. These rhetorical motifs and themes appeared only in the vendor-supported trials. Trials without vendor support described the drug's effects as "small" or absent; two emphasized the need for better treatments. RCT results were highly consistent in all trials; the small differences do not explain differences in rhetoric. At these text sites in the primary research literature on donepezil for AD, uniformly positive rhetoric is present in all vendor-supported RCTs. Reference to the limited benefit of donepezil is confined to RCTs without vendor support. Data in the trials are highly consistent. This observation generates the hypothesis that rhetoric in vendor-supported published RCTs may promote vendors' products. [source] Structural Factors Influencing Patterns of Drug Selling and Use and HIV Risk in the San Salvador Metropolitan AreaMEDICAL ANTHROPOLOGY QUARTERLY, Issue 2 2010Julia Dickson-Gomez This article explores differences in the social context in which crack sales and use and HIV risk take place in seven low-income communities in San Salvador, and structural factors that may influence these differences. The organization of drug selling varied among the communities on a number of dimensions including: whether drug sales were open or closed systems; the type of drug-selling site; and the participation of drug users in drug-distribution roles. Drug-use sites also varied according to whether crack was used in private, semiprivate, or public spaces, and whether individuals used drugs alone or with other drug users. Three patterns of drug use and selling were identified based on the dimensions outlined above. Structural factors that influenced these patterns included the geographic location of the communities, their physical layout, gang involvement in drug sales, and police surveillance. Implications for HIV risk and prevention are explored for each pattern. [source] The new Swedish Prescribed Drug Register,Opportunities for pharmacoepidemiological research and experience from the first six months,PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 7 2007Björn Wettermark M.Sc.Pharm Abstract Purpose To describe the content and potentials of the new Swedish national register on prescribed and dispensed medicines. Methods The Swedish Prescribed Drug Register contains information about age, sex and unique identifier of the patient as well as the prescriber's profession and practice. Information regarding drug utilization and expenditures for prescribed drugs in the entire Swedish population was extracted from the first six months July,December 2005 and compared with total drug sales in the country including OTC and hospital use. Results The total quantity of drugs sold in Sweden was 2666 million DDDs, corresponding to 1608 DDD/1000 inhabitants daily. The total expenditures were 1.6 billion Euro. The prescribed drugs, included in the register, accounted for 84% of the total utilization and 77% of the total expenditures. About half of all men and two-thirds of all women in the country purchased drugs. The proportion increased by age. The most common drugs for chronic treatment were diuretics among women (8.8% of the population) and antithrombotic agents among men (7.6%). Psychotropic drugs, corticosteroids and analgesics were more common among women, while men used antithrombotic agents, antidiabetic drugs, lipid lowering agents and ACE inhibitors to a greater extent. Conclusions The new register provides valuable data on exposure to drugs and is useful to study patterns of drug utilization. The possibilities for record linkage to other health registers gives from an international perspective good opportunities to explore drug and disease associations and the risks, benefits, effectiveness and health economical effects of drug use.

[source] There is a trend in the utilization of psychotropics among elderly towards recommended drugs,PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 10 2010Eva Lesén Abstract Purpose To analyse trends in sales of potentially inappropriate psychotropic substances (PIPS) in relation to drugs recommended by Drug and Therapeutics Committees (DTC drugs) among 75-year olds and among individuals born 1925 in Sweden. Methods Trends in sales of PIPS and DTC drugs among 75-year olds and among individuals born 1925 in Sweden during 2000,2008 were analysed with linear regression models. Sales were measured as defined daily doses per 1000 inhabitants and day. PIPS were defined according to a proposal from the Swedish National Board of Health and Welfare. The selection of DTC drugs was based on a review of recommendations from local DTCs. Results Among 75-year olds, PIPS sales decreased 38% and DTC drugs sales increased 31% from 2000 to 2008. The hypnotic PIPS decreased 45%, while the DTC hypnotics increased 36%. The total sales of PIPS to individuals born in 1925 decreased 12% from 2000 to 2008. The DTC drugs increased 115%. Sales of hypnotic PIPS decreased 12%, and the hypnotic DTC drugs increased 120%. Conclusions The findings indicate a trend towards the utilization of DTC drugs rather than PIPS.
