ObjectiveNewer non-benzodiazepines zolpidem and zopiclone ("Z-drugs") are often prescribed instead of benzodiazepine hypnotics, although there is no evidence of differences in effectiveness and safety. Aim was to compare perceptions on benefits and harms of benzodiazepines and Z-drugs between general practitioners (GPs) and community pharmacists (CPs).MethodsA questionnaire was mailed to a random sample of 1,350 GPs and 600 CPs in 2012. They were asked to rate perceptions on a five-point Likert scale used for both benzodiazepines and Z-drugs. Wilcoxon signed rank test was performed for the comparison of perceptions between GPs and CPs. Due to multiple testing, only p-values ≤0.01 were considered statistically significant.Results458 GPs and 202 CPs returned questionnaires (response 33.9% and 33.7%). Mean age of GPs was 53.3 years (40.6% female) and 48.8 years for CPs (59.2% females). Perceptions on benefits of benzodiazepines (and Z-drugs) between GPs and CPs were not different for 3 (and 2) of 5 items. Concerning side effects of benzodiazepines, there were no statistically significant differences for 3 of 5 comparisons. CPs perceived that 4 of 5 studied side effects of Z-drugs occur significantly more often than GPs (p=0.003 or less). For instance, whereas 45.2% of CPs answered that withdrawal effects on stopping happen often or very often/always on Z-drugs, these were only 28.3% of the GPs.ConclusionsAlthough it is difficult to draw unambiguous conclusions from these findings, pharmacists might have a somewhat more critical view on Z-drugs, especially concerning side effects.
