Key differences
Zyrtec belongs to Allergie und Antihistaminika while Vardenafil belongs to Erektile Dysfunktion (ED). 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
Zyrtec: Cetirizin blockiert selektiv periphere H1-Histaminrezeptoren und antagonisiert so die Wirkungen von Histamin, das von Mastzellen während allergischer Reaktionen freigesetzt wird. Vardenafil: Der Wirkmechanismus ist identisch mit dem von Levitra: Vardenafil hemmt selektiv die PDE5 in der glatten Muskulatur des Penis, sodass das während der sexuellen Erregung produzierte zyklische GMP akkumulieren kann.
When Zyrtec is preferred
Zyrtec ist bei Erwachsenen und Kindern zur Behandlung der saisonalen und perennialen allergischen Rhinitis, der allergischen Konjunktivitis und der chronischen idiopathischen Urtikaria zugelassen.
When Vardenafil is preferred
Generisches Vardenafil teilt die Indikation des Originalpräparats: erektile Dysfunktion bei erwachsenen Männern.
