Mechanism and action
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. 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 Lasix is preferred
