Previous experiments in hamsters indicate that daily injections of the short-acting benzodiazepine, triazolam, can entrain the free-running circadian activity rhythm to the period of the injections and that, after discontinuation of triazolam injections, the period of the free-running activity rhythm remains close to that of the previous injection schedule for 20-50 cycles. In this paper, we extend these findings and demonstrate that 1) long-term treatment with triazolam can induce aftereffects on the period of the circadian clock underlying the activity rhythm that can last for up to 100 days, 2) triazolam-induced changes in period can lead to a loss of effect of daily injections of triazolam which can be restored if the time of injection is altered, and 3) chronic treatment with triazolam also alters the period of the circadian clock in animals entrained to a light-dark cycle, and such changes in period alter the phase relationship between the circadian clock and the entraining light-dark cycle.
