Virkningsmekanisme Melatonins virkning på MT1, MT2 - og MT3- receptorer menes at bidrage til dens søvnfremmende egenskaber, da disse receptorer (hovedsageligt MT1 og MT2) er involveret i reguleringen af døgnrytmen og søvnen.
Mechanism of action The activity of melatonin at the MT1, MT2 and MT3 receptors is believed to contribute to its sleep- promoting properties, as these receptors (mainly MT1 and MT2) are involved in the regulation of circadian rhythms and sleep regulation.
