Ramelteon (ra mel' tee on) is a synthetic melatonin receptor agonist with affinity for both the melatonin type 1 and type 2 receptors (MT1 and MT2). These receptors are believed to be involved in the maintenance of the circadian rhythm that regulates the normal sleep-wake cycle.
Melatonin was available from health-food shops in the UK before 1995, but it was banned from general sale on the grounds that it was a medicinal product (previously, it was considered a nutritional supplement).
