We investigated the effects of (S)-N-[2-(1,6,7,8-tetrahydro-2H-indeno-[5,4]furan-8-yl)ethyl]propionamide (ramelteon, TAK-375), a novel MT1/MT2receptor agonist, on nocturnal sleep in freely moving monkeys and compared these results with those of melatonin and zolpidem. Treatment with ramelteon (0.03 and 0.3 mg/kg, p.o.) significantly shortened latency to sleep onset and significantly increased total duration of sleep. Treatment with melatonin (0.3, 1, and 3 mg/kg, p.o.) also decreased sleep latency, but the effect was weak; the only significant reduction was seen with the 0.3 mg/kg dose on latency to light sleep. Melatonin had no significant effects on the duration of sleep. Zolpidem had no significant effects on latency to sleep onset in this study at any dose (1, 3, 10, and 30 mg/kg, p.o.). The highest dose (30 mg/kg) of zolpidem had a tendency to increase slow wave sleep; however, it also induced apparent sedation and myorelaxation. Treatment with ramelteon and melatonin had no evident effect on the general behavior of the monkeys. Spectral analysis (fast Fourier transform, FFT) of both ramelteon and melatonin revealed sleep patterns that were indistinguishable from those of naturally occurring sleep. The EEG power spectra of zolpidem were qualitatively different from that of naturally occurring physiological sleep. Results of the present study support the investigation of ramelteon as a sleep-promoting agent in humans.
