Mechanism and action
Norvasc: Amlodipin blockiert selektiv L-Typ-Calciumkanäle in der glatten Gefäßmuskulatur, reduziert den transmembranen Calciumeinstrom und bewirkt eine periphere arterielle Vasodilatation. Lasix: Lasix wirkt in der Henle-Schleife der Niere, wo es den NKCC2-Cotransporter blockiert, der normalerweise Natrium, Chlorid und Kalium aus dem Harn in die Blutbahn rückresorbiert.
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 Lasix is preferred
Lasix ist zugelassen zur Behandlung der Flüssigkeitsüberladung bei Herzinsuffizienz, chronischer Nierenerkrankung und Leberzirrhose (mit oder ohne Aszites) sowie beim akuten Lungenödem.
