The effects of cannabis extracts on nocturnal sleep, early-morning performance, memory, and sleepiness were studied in 8 healthy volunteers (4 males, 4 females; 21 to 34 years). The study was double-blind and placebo-controlled with a 4-way crossover design. The 4 treatments were placebo, 15 mg Delta-9-tetrahydrocannabinol (THC), 5 mg THC combined with 5 mg(More)
1 The effect of the 1,5-benzodiazepines, clobazam (10 and 20 mg) and triflubazam (20 and 40 mg), on sleep was studied in six healthy males using electroencephalography for sleep measures and analogue scales for subjective assessments of well being and sleep quality. The effect of clobazam was limited to the night of ingestion. There was some evidence from(More)
The effects of an alpha 2-adrenoceptor agonist, clonidine and an antagonist, idazoxan, were studied on nocturnal sleep in man. Clonidine increased non-rapid eye movement sleep and idazoxan reduced slow wave sleep and increased awake activity. Changes in the continuity of sleep with clonidine were similar to, and those with idazoxan opposite to, the effects(More)
We have studied the acute effect of trimipramine (25, 50 and 75 mg) on nocturnal sleep in 6 young men. Fluoxetine (60 mg) and diazepam (10 mg) were included as controls for the potential changes in sleep measures. Trimipramine reduced awake activity, Stage 1 (drowsy) sleep, and the duration of rapid eye movement (REM) sleep. Non-REM (Stage 2) sleep was(More)
The effects of an inhibitor of the uptake of 5-hydroxytryptamine (5-HT) fluoxetine (20, 40 and 60 mg), on nocturnal sleep and on alertness during the day, were studied in healthy adults. Fluoxetine reduced the total sleep time and the duration of rapid eye movement (REM) sleep and increased awake activity and stage 1 (drowsy) sleep during the night. Daytime(More)
For hypnotics in which a fast elimination phase dominates the plasma decay, the initial fall in concentration from the peak value may nevertheless be slower than that of compounds with a sustained and rapid distribution. Drugs with fast elimination may therefore improve sleep throughout the rest period, even though residual sequelae, if any, around(More)
Effects of 10, 20 and 30 mg midazolam on sleep and on performance the next day were studied in six healthy adult males aged between 47 and 53 years. The study was double-blind, placebo-controlled and included another rapidly eliminated benzodiazepine (brotizolam, 0.25 mg) as an active control. With 10 mg midazolam, sleep-onset latency was quicker, and the(More)
1. The effects of 10 mg (+)- and (-)-chlorpheniramine and 5 mg (+)- and (-)-dimethindene on daytime sleep latencies, digit symbol substitution and subjective assessments of mood and well-being were studied in 6 healthy young adult humans. Each subject also took 5 mg triprolidine hydrochloride as an active control and two placebos. 2. Daytime sleep latencies(More)
Effects of H1 (mepyramine, mequitazine, triprolidine and brompheniramine) and H2 (cimetidine and ranitidine) antagonists on sleep were studied in healthy man. There were no effects of mepyramine (50 and 100 mg), and the only effect of mequitazine (5 and 10 mg) was a reduction in the number of awakenings. Triprolidine (10 and 20 mg) and brompheniramine (4(More)
