How does Sildenafil work?

Sildenafil helps you get and maintain an erection by helping more blood get into your penis when you are sexually aroused.

An erection is created by a compound chain of actions that involves the nervous system. The release of chemical messengers within the tissues of the penis as well. One of the couriers released when you are aroused is called cyclic GMP. It relaxes and widens the blood vessels in the penis. Wherein, it allows more blood to enter. This causes the penis to get hard and erect.

Cyclic GMP is normally broken down by an enzyme in the body called phosphodiesterase type-5 (PDE5). Sildenafil stops this enzyme from breaking down the cyclic GMP. It allows the blood vessels in the penis to stay dilated for longer. In which, it improves blood flow to the penis and helps produce and maintain an erection.

Sildenafil will only work once the messenger responsible for producing an erection starts to be produced. Therefore, you have to be sexually aroused for Sildenafil to create and keep an erection.
