Key differences
Viagra belongs to Dysfonction érectile while Lamictal belongs to Médicaments neurologiques. 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
Viagra: Lors de la stimulation sexuelle, du monoxyde d'azote est libéré dans le corps caverneux et active une enzyme qui produit du GMP cyclique. 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.
When Viagra is preferred

When Lamictal is preferred
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.
