Abstract
Ten healthy, normal subjects (5 male and 5 female) aged 20-28 years participated in this experimental study of the effect of moclobemide on sleep. The design consisted of 2 sessions of 5 nights each, comprising 1 adaptation night, 2 nights on placebo and 2 inputs of moclobemide 4 mg/kg (session B). The 2 sessions were separated by at least 15 days and their order was balanced and randomized. During the last 4 nights of each session, sleep parameters were recorded throughout the night according to standard procedures. Moclobemide at a dose of 4 mg/kg induced moderate changes in the sleep-wake balance: a significant increase in stage 1 on the second drug night, a slight increase in stage 2 and a significant decrease in paradoxical sleep on the 2 drug nights. There was also a moderate reduction in the number of rapid eye movements (REM) during paradoxical sleep, but the number of cycles and latency to paradoxical sleep were unchanged, as well as all other sleep parameters measured. With 6.5 mg/kg, the changes were more pronounced: total sleep time was diminished, but this was significant only on the second and third nights. Transient awakenings increased significantly on the first drug night, and wakening latency decreased. The only modification of orthodox sleep was an increase in the percentage of stage 2 on the first drug night, whereas slow-wave sleep was unchanged. Paradoxical sleep was reduced on the first 2 drug nights, but tolerance appeared on the third night. The decrease in paradoxical sleep was exacerbated in the last part of the night. REM were decreased during paradoxical sleep.(ABSTRACT TRUNCATED AT 250 WORDS)
