Abstract:
The effect on slow wave sleep (SWS) of 5-HT antagonists with different affinities for 5-HT(1) and 5-HT(2) receptors was investigated using ambulatory EEG monitoring in normal volunteers. The selective 5-HT( 2) antagonists, ritanserin and cypropheptadine, increased SWS while the non-selective 5-HT antagonist metergoline did not. The histamine H( 1)-receptor antagonist, mepyramine, was similarly without effect on SWS. These findings suggest that home ambulatory monitoring with automatic sleep stage analysis may be useful in detecting the effect of selective 5-HT( 2) receptor antagonists on SWS.

NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:
Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
