What is Fildena? Understanding its Working, Uses Dosage, Side Effects, and Interactions

Photo of author

Being unable to achieve a healthy erection during sexual activity is becoming common among men or Assigned Males at Birth (AMAB). 

It is commonly due to a sexual dysfunction known as Erectile Dysfunction (ED). Approximately 30 million men in the US are affected by ED.

However, there’s no need to worry if you are experiencing ED. It is a manageable sexual dysfunction.

There are several medications prescribed for treating ED, including Fildena. 

Let us dive into the article and find out what is Fildena, how it works, and what the complications are associated with Fildena.

What is Fildena

Fildena is a prescription-based ED medication that aids in improving the ability to achieve and maintain firm erections.

It helps to increase the flow of blood to the penis to achieve an erection during sexual intercourse.

It is the generic form of the most prescribed ED medicine, Viagra.

The active ingredient of Fildena is Sildenafil, an effective treatment for ED. It is also approved by the FDA or Food and Drug Administration for treating ED effectively.

What are the uses of Fildena

The primary use of Fildena is treating Erectile Dysfunction effectively and safely.

It helps enhance blood circulation in the penis to attain an erection during sexual intercourse.

Sildenafil in Fildena belongs to the group of medications called Phosphodiesterase 5 or PDE-5 inhibitors. According to a study, these PDE-5 inhibitors may aid in managing ED effectively.

Did you know?
Although Fildena is only used for treating ED, its key ingredient Sildenafil might also be prescribed for treating Pulmonary Arterial Hypertension (PAH).

How does Fildena work

As we already know, Fildena belongs to the class of medication called PDE-5 inhibitors.

Fildena works by inhibiting the effects of PDE-5 enzymes. These enzymes are responsible for the breakdown of a chemical known as cyclic Guanosine Monophosphate (cGMP).

Cyclic Guanosine Monophosphate plays an important role in achieving an erection by relaxing and widening the smooth muscles of the blood vessels of the penis. 

This relaxation causes an increase in the blood flow to the penis, causing an erection. 

When PDE 5 enzymes affect cGMP levels, this leads to reduced blood flow to the penis, causing loss of erection.

Fildena inhibits the PDE-5 enzyme and increases the production of cGMP, which causes an increase in the blood flow to the penile region, leading to firm erections

It is vital to note that Fildena only works when an individual is sexually stimulated.
