Key differences
Norvasc belongs to Herz-Kreislauf-Medikamente while Klonopin belongs to Angstlösende 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
Norvasc: Amlodipin blockiert selektiv L-Typ-Calciumkanäle in der glatten Gefäßmuskulatur, reduziert den transmembranen Calciumeinstrom und bewirkt eine periphere arterielle Vasodilatation. Klonopin: Clonazepam bindet an die Benzodiazepin-Bindungsstelle des GABA-A-Rezeptors und verstärkt allosterisch die hemmende Chlorid-Leitfähigkeit, wodurch ZNS-Neuronen hyperpolarisiert werden.
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.
When Klonopin is preferred
Klonopin ist bei Erwachsenen zur Behandlung bestimmter Anfallsarten zugelassen, einschließlich Absencen und atypischer Absencen, myoklonischer und akinetischer Anfälle sowie als Zusatztherapie beim Lennox-Gastaut-Syndrom.
