Fildena and Viagra both contain sildenafil citrate and work similarly to treat erectile dysfunction. Viagra, the FDA-approved brand, has been available since 1998 and is known for its proven safety, but it comes at a higher cost. Fildena, a generic alternative introduced in 2013, offers the same effectiveness at a more affordable price. The choice between the two depends on budget, preference, and medical advice, making a doctor’s consultation essential before use.

Erectile dysfunction (ED) is a common issue that affects millions of men worldwide. It can impact confidence, relationships, and overall quality of life. Fortunately, medical advancements have made ED more manageable with the help of effective treatments. One of the most widely used solutions for ED is Sildenafil, a medication that helps men regain their sexual performance. Among Sildenafil-based treatments, Viagra and Fildena are the two popular options available in the market today. But in this Fildena vs Viagra comparison, which is a better option for you?

Is there a difference in effectiveness, safety, or value? In this guide, we will look into Fildena and Viagra, helping you choose the right ED medication for your needs.

Understanding Sildenafil Citrate

Sildenafil Citrate is a prescription medication primarily used to treat erectile dysfunction in men by increasing blood flow to the penis during sexual stimulation. It belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors, which work by relaxing the blood vessels and improving circulation in specific areas of the body.

First approved by the U.S. FDA in 1998, Sildenafil became widely recognized under the brand name Viagra.

While sildenafil citrate is widely recognized for its role in managing ED, its clinical use extends far beyond sexual health-

According to Dr. Goldstein, Clinical Professor of Surgery at the University of California, San Diego and Director of San Diego Sexual Medicine, sildenafil citrate can reduce the intensity and progression of erectile dysfunction over time. Beyond sexual function, sildenafil citrate is also a recognized treatment for pulmonary arterial hypertension (PAH). It is a type of high blood pressure that affects the lungs. It improves the ability to exercise and delays disease progression.

What Is Viagra?

Viagra is a medication developed by Pfizer and used to treat erectile dysfunction in men. Its active ingredient, sildenafil citrate, works by increasing blood flow to the penis, helping achieve and maintain an erection when sexually aroused [1].

What Is Fildena?

Fildena is a generic version of Viagra containing sildenafil citrate as the active compound. It was developed after Viagra’s patent expired, allowing pharmaceutical companies to produce more affordable alternatives.

Apart from Fildena, several other generic Sildenafil options are available, offering multiple dosage strengths. Some of them are Cenforce, Malegra, and Aurogra. Beginners can start with a lower dose, such as Cenforce 100 mg, to see how their body responds.

Fildena Vs Viagra- Key Similarities

Fildena Vs Viagra- Key Similarities

The key similarities between Viagra and Fildena ED medication are listed below.

Same Active Ingredient

Both Fildena and Viagra contain sildenafil citrate as the active compound. It is a PDE5 inhibitor that improves blood flow to the penis, helping achieve and maintain an erection.

Same Mechanism of Action

Fildena and Viagra works by enhancing blood flow to the penis. This helps men to achieve and maintain an erection. Its action begins when a man experiences sexual arousal, triggering the release of nitric oxide (NO) in the blood vessels of the penis. Nitric oxide activates the enzyme guanylate cyclase, which increases the levels of cyclic guanosine monophosphate (cGMP). This cGMP is crucial for relaxing the smooth muscles in the corpus cavernosum (the erectile tissue), allowing the blood vessels to expand (vasodilation) and blood to flow in more freely [2].

Onset of Action

Both Fildena and Viagra tablets take around 30 to 60 minutes to start working after intake.

Duration Of Action

The effects of Viagra and Fildena ED medication last for about 4 to 6 hours.
