Mechanism and action
Lamictal: Lamotrigin blockiert selektiv spannungsabhängige Natriumkanäle, stabilisiert neuronale Membranen und reduziert die Freisetzung exzitatorischer Neurotransmitter, insbesondere Glutamat. Norvasc: Amlodipin blockiert selektiv L-Typ-Calciumkanäle in der glatten Gefäßmuskulatur, reduziert den transmembranen Calciumeinstrom und bewirkt eine periphere arterielle Vasodilatation.
When Lamictal is preferred
Lamictal ist bei Erwachsenen und Kindern ab 2 Jahren als Zusatz- oder Monotherapie bei fokalen Anfällen, primär generalisierten tonisch-klonischen Anfällen sowie Anfällen im Rahmen des Lennox-Gastaut-Syndroms zugelassen.
When Norvasc is preferred
Norvasc ist bei Erwachsenen zur Behandlung der essenziellen arteriellen Hypertonie und der chronischen stabilen Angina pectoris sowie der vasospastischen Angina pectoris (Prinzmetal-Angina) zugelassen.
