RATIONALE Histamine and dopamine contribute to the maintenance of wakefulness. OBJECTIVE This study aims to conduct an exploratory analysis of the effects of 10 and 50 mg of MK-0249, a novel histamine subtype-3 receptor inverse agonist, and 200 mg of modafinil, a presumed dopaminergic compound, on EEG power spectra during sleep deprivation and subsequent(More)
Sudden intense sensory stimuli elicit a cascade of involuntary responses, including a short-latency skeletal muscular response ('eyeblink startle response') and longer-latency autonomic responses. These responses are enhanced when subjects anticipate an aversive event compared to periods when subjects are resting ('fear potentiation'). It has been reported(More)
RATIONALE Enhancement of histaminergic neurotransmission or histaminergic plus cholinergic neurotransmission may represent novel strategies for improving cognition in Alzheimer's disease. OBJECTIVE To evaluate the effects of a novel histamine H3 receptor inverse agonist (MK-3134), an acetylcholinesterase inhibitor (donepezil), and their combination in(More)
UNLABELLED Intradermal (ID) capsaicin injection in humans induces spontaneous pain, flare, primary hyperalgesia, secondary hyperalgesia, and allodynia. Secondary hyperalgesia and allodynia are a reflection of central sensitization. The effect of treatment of single doses of (1) pregabalin, 300 mg single oral dose, and (2) morphine, 10 mg IV, on the area of(More)
Orexin neuropeptides regulate sleep/wake through orexin receptors (OX1R, OX2R); OX2R is the predominant mediator of arousal promotion. The potential for single OX2R antagonism to effectively promote sleep has yet to be demonstrated in humans. MK-1064 is an OX2R-single antagonist. Preclinically, MK-1064 promotes sleep and increases both rapid eye movement(More)
Rationale: Histamine and dopamine contribute to the maintenance of wakefulness. Objective: Exploratory analysis of the effects of 10 and 50 mg of MK-0249, a novel histamine subtype-3 receptor inverse agonist, and 200 mg of modafinil, a presumed dopaminergic compound, on EEG power spectra during sleep deprivation and subsequent recovery sleep.

The alertness-promoting effect of MK-0249 (10 or 50 mg), a histamine subtype-3 receptor (HRH3) inverse agonist (IA), was evaluated in the stimulant reference sleep deprivation model (SRSDM) using a double-blind, double-dummy, placebo- and modafinil- (200 mg) controlled, four-period crossover design in 24 healthy young men. The two primary hypotheses were(More)
