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. Livial: La tibolone contenue dans Livial est rapidement convertie en trois métabolites actifs à activité sélective des tissus.
