Mechanism and action
Januvia: La sitagliptine inhibe de façon réversible la DPP-4, enzyme responsable de la dégradation rapide du GLP-1 et du GIP. Levitra: Lors de la stimulation sexuelle, du monoxyde d'azote est libéré dans le corps caverneux et active une enzyme produisant du GMP cyclique, qui relâche le muscle lisse et augmente l'afflux sanguin nécessaire à l'érection.
When Januvia is preferred
