Mirtazapine vs Bupropion: side-by-side comparison
Mirtazapine (Atypical antidepressant (NaSSA)) and Bupropion (Norepinephrine-dopamine reuptake inhibitor (NDRI) antidepressant) belong to different therapeutic classes and are rarely substitutes for each other. The comparison is useful when a single patient is weighing both options for adjacent or overlapping needs.

What they share
Mirtazapine and Bupropion share the common regulatory framework for prescription active ingredients, bioequivalence standards for generics, and pharmacist oversight. Beyond that, points in common are limited.
Key differences
Mirtazapine acts by a different mechanism than Bupropion, with indications that barely overlap. Comparing the two is useful when a clinician has mentioned both in the same context or the patient wants to understand why one was prescribed instead of the other.
Mechanisms compared
Mirtazapine: La mirtazapine antagonise les autorécepteurs et hétérorécepteurs α2-adrénergiques présynaptiques, ce qui augmente la libération de noradrénaline et de sérotonine. 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.
Indications compared
Mirtazapine: La mirtazapine est autorisée dans la dépression caractérisée. Bupropion: Le bupropion est autorisé dans la dépression caractérisée, la prévention des récidives de trouble affectif saisonnier et le sevrage tabagique.

Mirtazapine: Les effets indésirables fréquents comprennent la sédation (maximale aux faibles doses de 7,5 à 15 mg, paradoxalement moindre aux doses supérieures), l'augmentation de l'appétit, la prise de poids, la sécheresse buccale e… Bupropion: Les effets indésirables fréquents comprennent sécheresse buccale, insomnie, céphalées, agitation, nausées et perte de poids.
Questions fréquentes
Is Mirtazapine better than Bupropion? ▾
Mirtazapine and Bupropion are not "better or worse" — they treat different things. The sensible question is which fits your specific need.
Can Mirtazapine and Bupropion be combined? ▾
Whether they can be combined depends on the indications and the interaction profile of each. If both are in a single prescription, the prescriber has weighed it; in self-medication they should never be combined.
Do they have the same side-effect profile? ▾
No — they belong to different classes and have distinct side-effect profiles. Each has its own prescribing information.
