Mechanisms compared
Avanafil: L'avanafil inhibe sélectivement la phosphodiestérase de type 5 dans le corps caverneux, ce qui augmente le GMP cyclique et amplifie la vasodilatation médiée par le monoxyde d'azote en réponse à la stimulation sexuelle. Sildenafil Citrate: Le citrate de sildénafil inhibe sélectivement la phosphodiestérase de type 5 (PDE5), l'enzyme qui dégrade le guanosine monophosphate cyclique dans le corps caverneux.
Indications compared
Avanafil: L'avanafil est autorisé dans la dysfonction érectile chez l'homme adulte. Sildenafil Citrate: Le citrate de sildénafil est autorisé chez l'homme adulte dans le traitement de la dysfonction érectile.
