Mechanism and action
Yaz: Yaz prévient la grossesse par trois mécanismes : le blocage de l'ovulation (effet dominant), l'épaississement de la glaire cervicale qui gêne le passage des spermatozoïdes, et la modification de la réceptivité de l'endom… 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 Yaz is preferred
Yaz est autorisé dans la contraception chez la femme adulte demandant un contraceptif oral, dans le traitement du trouble dysphorique prémenstruel et dans celui de l'acné modérée chez la femme de 14 ans et plus demandant également une contraception.
