Mechanism and action
Claritin: Loratadin blockiert selektiv periphere H1-Histaminrezeptoren und antagonisiert die Histaminwirkung bei allergischen Reaktionen. Celexa: Citalopram hemmt selektiv den Serotonin-Reuptake-Transporter und erhöht damit die synaptische Serotoninverfügbarkeit, mit nur begrenzter Affinität zu Noradrenalin-Transportern oder anderen Rezeptoren.
When Claritin is preferred
Claritin ist bei Erwachsenen und Kindern zur Behandlung der saisonalen und perennialen allergischen Rhinitis sowie der chronischen idiopathischen Urtikaria zugelassen.
When Celexa is preferred
