비아그라 contains the active ingredient sildenafil which belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. It works by helping the blood vessels in the penis to dilate so that blood can flow to the penis when you are sexually stimulated. 비아그라 can only help you get an erection if you are sexually stimulated.
비아그라 is a treatment for adult men with erectile dysfunction, better known as impotence. This means that one cannot get or keep a hard, erect penis, sufficient for sexual activity.
