Melatonergic MT1 MT2 receptors exist high concentrations suprachiasmatic nucleus hypothalamus have shown be instrumental sleep-promoting rhythm-regulating effects melatonin. A lack consistency among reports on therapeutic efficacy melatonin attributed differences melatonin’s bioavailability short half-life hormone. In view need longer acting melatonergic agonists that efficiency without causing drug abuse or dependency, ramelteon (Rozerem™, Takeda) was developed. Ramelteon, which acts via MT1/MT2 agonism, found clinically effective improving total time insomniacs. Agomelatine (Valdoxan™, Servier) is another agonist...
