This page compares them: when each is used, how the mechanisms and indications differ, and whether the question "Allegra vs Bupropion" makes sense to ask at all.
What is the relationship?

They belong to different therapeutic classes and are chosen for different indications.

When Bupropion is used
Le bupropion est autorisé dans la dépression caractérisée, la prévention des récidives de trouble affectif saisonnier et le sevrage tabagique.
Mechanisms compared
Allegra: La fexofénadine bloque sélectivement les récepteurs H1 périphériques de l'histamine, antagonisant ses effets sur la vasodilatation, la perméabilité capillaire, les terminaisons nerveuses sensitives et le muscle lisse. Bupropion: Le bupropion inhibe la recapture de la noradrénaline et de la dopamine, avec un effet nettement plus faible sur la recapture de la sérotonine.
When the comparison makes sense
