Erectile dysfunction is defined as a condition in which maintaining and attaining satisfied erections is a questionable aspect for a man.

There are many factors that play a role in the functioning of erectile system and impairment in any factor can lead to the development of erectile dysfunction.

Sildenafil is an oral phosphodiesterase type 5 inhibitor which is considered to be one of the best therapy for erectile dysfunction and it is due to its effectiveness and low rate side effects. Not only erectile dysfunction, sildenafil is also a recommended dose to treat other sexual problems. Sildenafil is a hypertensive drug. Multiple studies have reported that a significant improvement is witnessed in patients having erectile dysfunction after consumption of sildenafil as compared to those patients who did not take sildenafil.
Getting an erection is a complicated process which requires an increased flow of blood in the penis region which results from the messages that are sent to the blood vessels in the penis. Sildenafil works by blocking or inhibiting the phosphodiesterase enzyme which leads to the degradation of cGMP (Cyclic guanosine monophosphate). Availability of cGMP is important to get or maintain the proper erection as it relaxes the muscles in the penis region and allows the blood flow to the penis region, which results in an erection. It is important to note that sildenafil works only after sexual stimulation. This is because When the brain senses sexual stimulation, it sends an impulse to the nerves of the penis that causes the muscles of the corpora muscles to relax.
