Reactions 1704, p12 - 2 Jun 2018 Risk of fatal motor vehicle collisions in zolpidem users A prescription for zolpidem on the previous day is associated with an increased risk of motor vehicle collisions (MVCs), according to the results of a study in South Korea reported in Drug Safety, indicating that "more education for healthcare professionals and patients who drive is needed". The case-crossover study included drivers who died of MVCs in 2010–2014 and who received a prescription for zolpidem during the preceding year. The one-day case period prior to the MVC was compared with 4 earlier one-day control periods, 90 days apart. Of the 7061 included drivers, with a mean age of 61.6 years, 714 patients had prescriptions for zolpidem. The zolpidem prescription frequency was 105 (14.8%) during the case period and 354 (12.4%) during the control periods. In conditional regression analysis, after adjustment for time-varying exposure to confounding medications, zolpidem was associated with an increased risk of fatal MVCs (odds ratio [OR] 1.48; 95% CI 1.06, 2.07). The risk was significantly increased for new zolpidem users (OR 2.37; 1.40, 4.00), but not for patients with a record of prescriptions for zolpidem 1 year prior to the study period. The MVC risk was increased in patients with a Charlson Comorbidity Index score ≥5 (OR 1.81; 1.16, 2.84), which the authors note "might be associated with drug interactions of zolpidem". The risk was also increased in patients <65 years of age (OR 1.62; 1.03, 2.56). The absence of an association in older drivers "may be explained by their driving patterns," note the authors, or their "relatively long driving experience". Yang BR, et al.
