1 We all want bright, white smiles â they can take years off your appearance and boost your confidence. 2  And while bleaching your teeth is an effective (and generally safe) whitening step, it also helps to avoid foods that stain teeth in the first place.
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.
Of the two, MT1 is most specific for sedation, and Rozerem has a 15-fold greater affinity for MT1 than straight melatonin, a fact that probably accounts for why melatonin is only mildly effective as a sleep aid (see this meta-analysis of melatonin studies: Brzezinski A et al., Sleep Med Rev 2005;9:41-50).
