Mechanism and action
Wellbutrin: Wellbutrin hemmt die Wiederaufnahme von Noradrenalin und Dopamin, mit deutlich schwächerer Wirkung auf Serotonin. Lamictal: Lamotrigin blockiert selektiv spannungsabhängige Natriumkanäle, stabilisiert neuronale Membranen und reduziert die Freisetzung exzitatorischer Neurotransmitter, insbesondere Glutamat.
