Key differences
Pepcid belongs to Gastrointestinale Medikamente while Viagra Professional 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
Pepcid: Famotidin blockiert reversibel und kompetitiv die Histamin-H2-Rezeptoren an den Belegzellen des Magens und vermindert sowohl die basale als auch die stimulierte Magensäuresekretion. 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 Pepcid is preferred
Pepcid ist bei Erwachsenen und Kindern zur Kurzzeitbehandlung des aktiven Duodenal- und Magenulkus, zur Erhaltungstherapie des Duodenalulkus, der gastroösophagealen Refluxkrankheit, des Zollinger-Ellison-Syndroms und anderer hypersekretorischer Zustände zugelassen.
