ECHEMI Editorial ReferenceThe selectivity of the resulting ramelteon for MT1 receptor iseight times more than that of MT2 receptor. Unlike melatonin,it is more effective in initiating sleep (MT1 activity)rather than to readjust the circadian rhythm (MT2 activity). Itappears to be distinctly more efficacious than melatonin butless efficacious than benzodiazepines as a hypnotic.Importantly, this drug has no addiction liability (it is not acontrolled substance). As a result, it has recently been approvedfor the treatment o

N-[2-[(8S)-2,6,7,8-tetrahydro-1H-cyclopenta[e]benzofuran-8-yl]ethyl]propanamide is a member of indanes.|Ramelteon is the first in a new class of sleep agents that selectively binds to the melatonin receptors in the suprachiasmatic nucleus (SCN). It is used for insomnia, particularly delayed sleep onset. Ramelteon has not been shown to produce dependence and has shown no potential for abuse.|Ramelteon is a Melatonin Receptor Agonist. The mechanism of action of ramelteon is as a Melatonin Receptor Agonist.|Ramelteon is a melatonin receptor agonist that is used for the treatment of insomnia. Ramelteon has not been implicated in causing serum enzyme elevations or clinically apparent liver injury.|Ramelteon is a synthetic melatonin analogue with hypnotic and circadian rhythm-modulating activities. Ramelteon binds to and activates melatonin receptors 1 and 2 in the suprachiasmatic nucleus (SCN) of the brain, thereby promoting the onset of sleep. Unlike the nonbenzodiazepine sedative hypnotics zolpidem and zaleplon, this agent does not activate GABA receptors and, so, produces no GABA receptor-mediated anxiolytic, myorelaxant, and amnesic effects.Basic Info-
