Mechanisms compared
Mirtazapine: La mirtazapine antagonise les autorécepteurs et hétérorécepteurs α2-adrénergiques présynaptiques, ce qui augmente la libération de noradrénaline et de sérotonine. Conjugated Estrogens: Les estrogènes conjugués agissent sur les récepteurs des estrogènes de l'ensemble de l'organisme, restaurant la signalisation estrogénique perdue après la ménopause.
