Mechanism and action
Claritin: Loratadin blockiert selektiv periphere H1-Histaminrezeptoren und antagonisiert die Histaminwirkung bei allergischen Reaktionen. 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 Claritin is preferred
Claritin ist bei Erwachsenen und Kindern zur Behandlung der saisonalen und perennialen allergischen Rhinitis sowie der chronischen idiopathischen Urtikaria zugelassen.
When Viagra Professional is preferred
