Det virker på to måder, både ved at stimulere MT1 - og MT2- receptorerne, som normalt aktiveres af melatonin, og ved at blokere 5- HT 2C - receptorerne, som normalt aktiveres af neurotransmitteren 5- hydroxytryptamin (også kaldet serotonin).
It works in two ways, both by stimulating the MT1 and MT2 receptors, which are normally activated by melatonin, and also by blocking the 5-HT 2C receptors, which are normally activated by the neurotransmitter 5-hydroxytryptamine (also called serotonin).
