ZOlpidem and the stRengthening of pRescription regulatiOn

For several years, the French Addictovigilance Network (FAN) highlights potential problematic consumptions with zolpidem. To prevent abuse and misuse of zolpidem, the French Health Products Agency has changed the regulatory framework of zolpidem prescription. Thus, since the 10th of April 2017 zolpidem prescriptions have to be secured (particular support, dosage written out). The investigators hypothesized that this change will affect zolpidem consumption but also the consumption of all sedative drugs. In order to assess the incidence of the regulatory change for zolpidem prescription the investigators conduct a two part study: an epidemiological study with French National Health Insurance Fund for Employees database and an observational study with general practitioners and zolpidem consumers.
