Key differences
Neurontin belongs to Neurologische Arzneimittel while Norvasc belongs to Herz-Kreislauf-Medikamente. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Neurontin: Gabapentin bindet an die Alpha-2-Delta-Hilfsuntereinheit spannungsabhängiger Calciumkanäle im zentralen Nervensystem und reduziert dadurch den präsynaptischen Calciumeinstrom sowie die Freisetzung exzitatorischer Neurotr… Norvasc: Amlodipin blockiert selektiv L-Typ-Calciumkanäle in der glatten Gefäßmuskulatur, reduziert den transmembranen Calciumeinstrom und bewirkt eine periphere arterielle Vasodilatation.
When Neurontin is preferred
Neurontin ist bei Erwachsenen und Kindern ab drei Jahren zur Zusatztherapie fokaler Anfälle und bei Erwachsenen zur Behandlung der postherpetischen Neuralgie 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.
