Key differences

Mechanism and action
Norvasc: Amlodipin blockiert selektiv L-Typ-Calciumkanäle in der glatten Gefäßmuskulatur, reduziert den transmembranen Calciumeinstrom und bewirkt eine periphere arterielle Vasodilatation. Viagra Professional: Sildenafilcitrat hemmt die PDE5, sodass das während der sexuellen Erregung produzierte zyklische GMP im Penisgewebe akkumulieren kann, was die glatte Muskulatur der Penisarterien entspannt und den Bluteinstrom erhöht.
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 Viagra Professional is preferred
