Mechanism and action
Lamictal: Lamotrigin blockiert selektiv spannungsabhängige Natriumkanäle, stabilisiert neuronale Membranen und reduziert die Freisetzung exzitatorischer Neurotransmitter, insbesondere Glutamat. Doxycycline: Doxycyclin bindet reversibel an die 30S-Untereinheit bakterieller Ribosomen, verhindert die Bindung von Aminoacyl-tRNA und hemmt damit die Proteinsynthese.
