Randomized Controlled Trial
Sleep and residual sedation after administration of zaleplon, zolpidem, and placebo during experimental middle-of-the-night awakening.
To assess the efficacy of zaleplon 10 mg and zolpidem 10 mg administered during experimental middle-of-the-night awakenings in patients with sleep-maintenance insomnia using objective polysomnographic measures and to assess daytime residual sedation 4 to 7 hours after dosing using sleep-latency testing. ⋯ Zaleplon 10 mg and zolpidem 10 mg effectively shorten sleep latency and lengthen sleep duration after dosing, when administered during experimental nocturnal awakening. Residual sedation was not detected as little as 4 hours after zaleplon 10 mg, whereas residual sedation was detected with zolpidem 10 mg up to 7 hours after treatment. These findings suggest that zaleplon may be an appropriate treatment for use when patients awaken during the night and have difficulty reinitiating sleep.
