- Description
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.

Pharmacology
- Indication
For the treatment of insomnia characterized by difficulty with sleep onset.
- Associated Conditions
- Pharmacodynamics
Ramelteon is the first selective melatonin agonist. It works by mimicking melatonin (MT), a naturally occuring hormone that is produced during the sleep period and thought to be responsible for the regulation of circadian rhythm underlying the normal sleep-wake cycle. Ramelteon has a high affinity for the MT1 and MT2 receptors. The MT1 and MT2 receptors are located in the brain's suprachiasmatic nuclei (SCN),which is known as the body's "master clock" because it regulates the 24-hour sleep-wake cycle. Ramelteon has an active metabolite that is less potent but circulates in higher concentrations than the parent compound. The metabolite also has weak affinity for the 5HT2b receptor.
- Mechanism of action
Ramelteon is a melatonin receptor agonist with both high affinity for melatonin MT1 and MT2 receptors, and lower selectivity for the MT3 receptor. Melatonin production is concurrent with nocturnal sleep, meaning that an increase in melatonin levels is related to the onset of self-reported sleepiness and an increase in sleep propensity. MT1 receptors are believed to be responsible for regulation of sleepiness and facilitation of sleep onset, and MT2 receptors are believed to mediate phase-shifting effects of melatonin on the circadian rhythm. While MT1 and MT2 receptors are associated with the sleep-wake cycle, MT3 has a completely different profile, and therefore is not likely to be involved in the sleep-wake cycle. Remelteon has no appreciable affinity for the gamma-aminobutyric acid (GABA) receptor complex or receptors that bind neuropeptides, cytokines, serotonin, dopamine, norepinephrine, acetylcholine, or opiates.
