Key differences
Lamictal belongs to Médicaments neurologiques while Prozac belongs to Antidépresseurs. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Lamictal: La lamotrigine bloque sélectivement les canaux sodiques voltage-dépendants, stabilisant les membranes neuronales et réduisant la libération de neurotransmetteurs excitateurs, en particulier le glutamate. Prozac: La fluoxétine inhibe sélectivement le transporteur de recapture de la sérotonine, augmentant sa disponibilité synaptique.

Lamictal est autorisé chez l'adulte et l'enfant à partir de 2 ans, en adjuvant ou en monothérapie, dans les crises partielles, les crises tonico-cloniques généralisées primaires et les crises associées au syndrome de Lennox-Gastaut.
