Mechanism and action
Celexa: Citalopram hemmt selektiv den Serotonin-Reuptake-Transporter und erhöht damit die synaptische Serotoninverfügbarkeit, mit nur begrenzter Affinität zu Noradrenalin-Transportern oder anderen Rezeptoren. Remeron: Mirtazapin antagonisiert präsynaptische α2-adrenerge Rezeptoren und steigert dadurch die Freisetzung von Noradrenalin und Serotonin.
