Mechanisms compared
Lamictal: Lamotrigin blockiert selektiv spannungsabhängige Natriumkanäle, stabilisiert neuronale Membranen und reduziert die Freisetzung exzitatorischer Neurotransmitter, insbesondere Glutamat. Fluoxetine: Fluoxetin hemmt selektiv den Serotonin-Wiederaufnahmetransporter und erhöht so die synaptische Verfügbarkeit von Serotonin.
