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. Lexapro: Lexapro wirkt durch selektive Hemmung des Serotonin-Wiederaufnahmetransporters (SERT) an der Synapse und erhöht so die Verfügbarkeit von Serotonin für postsynaptische Rezeptoren.
