The mechanism of action of sildenafil: the drug increases the amount of blood entering the penis. This helps a man to cause a natural erection. Sildenafil acts only when the man experiences natural sexual arousal, and when the sexual intercourse is completed, the penis naturally returns to a relaxed state. In other words, sildenafil acts only on the natural mechanisms of erection. |
