The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Glucophage: Metformin senkt die hepatische Glukoseproduktion durch Hemmung des mitochondrialen Komplexes I, wodurch das zelluläre AMP/ATP-Verhältnis steigt und die AMP-aktivierte Proteinkinase aktiviert wird. 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 Glucophage is preferred
Das Arzneimittel ist als orale First-Line-Therapie bei Erwachsenen mit Diabetes mellitus Typ 2 indiziert, allein oder in Kombination mit anderen Antidiabetika einschließlich Insulin.
When Viagra Professional is preferred
