Mechanism and action
Claritin: La loratadine bloque sélectivement les récepteurs H1 périphériques de l'histamine, antagonisant ses effets lors des réactions allergiques. Celexa: Le citalopram inhibe sélectivement le transporteur de recapture de la sérotonine, augmentant sa disponibilité synaptique avec une affinité limitée pour les transporteurs de la noradrénaline ou les autres récepteurs.
When Claritin is preferred
Claritin est autorisé chez l'adulte et l'enfant dans le traitement de la rhinite allergique saisonnière et perannuelle et de l'urticaire chronique idiopathique.
