Key differences
Viagra belongs to Dysfonction érectile while Glucophage belongs to Traitement du diabète. 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
Viagra: Lors de la stimulation sexuelle, du monoxyde d'azote est libéré dans le corps caverneux et active une enzyme qui produit du GMP cyclique. Glucophage: La metformine réduit la production hépatique de glucose en inhibant le complexe I mitochondrial, ce qui élève le rapport AMP/ATP cellulaire et active l'AMP-kinase.
When Viagra is preferred
Le médicament est indiqué chez l'homme adulte dans le traitement de la dysfonction érectile, définie comme l'incapacité à obtenir ou à maintenir une érection suffisante pour l'activité sexuelle.
When Glucophage is preferred
Le médicament est indiqué en traitement oral de première intention chez l'adulte atteint de diabète de type 2, seul ou en association à d'autres antidiabétiques, dont l'insuline.
