An epidemiologic study was conducted to observe patient-reported use and effects of triazolam, flurazepam, and oxazepam taken at bedtime among 2260 outpatients age 65 years or older in Canada. The study used pharmacy-based enrollment, with participant follow-up through a 3-day diary and a telephone interview. The study also evaluated how the three benzodiazepine hypnotics were prescribed. Prescription information showed that 66% of the flurazepam prescriptions were for the highest strength, compared to 39% and 35% for triazolam and oxazepam, respectively. As patient age increased, the highest strength of each agent was prescribed less frequently. For all drugs, 53% of prescriptions were written for use as necessary (prn), and the proportion who received such prescriptions increased with age. Patient reports, however, revealed that 57% were using a hypnotic every day, and this regular use increased with advancing age. Regular daily use was more common among those who used triazolam and oxazepam (62%) than those who took flurazepam (42%).
