What is the Fildena tablet used for, and how does it work?


Buy Fildena Online is a pharmaceutical product known for its use in treating erectile dysfunction (ED) in men. Erectile dysfunction is a prevalent condition characterized by the inability to achieve or maintain an erection sufficient for sexual intercourse. Fildena contains an active ingredient called sildenafil citrate, a potent and selective inhibitor of the enzyme phosphodiesterase type 5 (PDE5). In this article, we will delve into the uses of Fildena tablets, exploring how they work to alleviate erectile dysfunction and providing insights into their mechanism of action.

Uses of Fildena Tablets

Erectile Dysfunction Treatment

The primary use of Fildena tablets is in the treatment of erectile dysfunction. ED can be caused by various factors, including psychological issues, hormonal imbalances, and underlying health conditions. Fildena helps address this condition by enhancing blood flow to the penile tissues, facilitating the attainment and maintenance of an erection during sexual stimulation.

Pulmonary Arterial Hypertension

Besides its well-known application for erectile dysfunction, sildenafil, the active ingredient in Generic Viagra Online, is also used to treat pulmonary arterial hypertension (PAH). PAH is a condition characterized by elevated blood pressure in the arteries that supply the lungs, making it difficult for the heart to pump blood through the pulmonary system. Fildena, in such cases, acts by relaxing the arterial walls, reducing pulmonary resistance, and improving exercise capacity.

Mechanism of Action

Inhibition of PDE5

The key to Fildena’s effectiveness lies in its ability to inhibit the enzyme phosphodiesterase type 5 (PDE5). PDE5 is responsible for the degradation of cyclic guanosine monophosphate (cGMP), a molecule that plays a crucial role in smooth muscle relaxation. In the absence of sexual stimulation, nitric oxide is released in the erectile tissue of the penis, leading to the synthesis of cGMP. However, PDE5 breaks down cGMP, preventing its accumulation and thereby reducing the ability of the smooth muscles in the penile arteries to relax.

Enhanced Nitric Oxide Action

Nitric oxide (NO) is a signaling molecule that plays a pivotal role in the erectile response. It is released from nerve endings and endothelial cells in response to sexual stimulation. Nitric oxide activates an enzyme called guanylate cyclase, which, in turn, increases the production of cGMP. Fildena works by inhibiting PDE5, allowing cGMP to accumulate, and promoting prolonged relaxation of the smooth muscles in the penile arteries. This enhanced relaxation facilitates increased blood flow to the erectile tissues, resulting in an erection.

Smooth Muscle Relaxation

The inhibition of PDE5 by Fildena leads to the accumulation of cGMP, promoting the relaxation of smooth muscle cells in the corpus cavernosum of the penis. This relaxation allows blood vessels to dilate, increasing blood flow to the erectile tissues. As a result, the penis becomes engorged with blood, leading to an erection that is sufficient for sexual activity.

Dual Action in PAH

In the case of pulmonary arterial hypertension, Fildena’s mechanism of action involves the same principle of PDE5 inhibition. By relaxing the smooth muscles in the pulmonary arteries, Fildena reduces resistance and pressure in the pulmonary circulation, improving blood flow to the lungs and alleviating symptoms associated with PAH.


Fildena tablets, with sildenafil citrate as their active ingredient, offer an effective solution for individuals experiencing erectile dysfunction. By inhibiting the enzyme PDE5 and enhancing the action of nitric oxide, Fildena promotes smooth muscle relaxation in the penile arteries, allowing for increased blood flow and the achievement of a satisfactory erection. Additionally, Fildena finds application in the treatment of pulmonary arterial hypertension, showcasing its versatility in addressing vascular issues beyond erectile dysfunction. While Fildena can be a valuable tool in managing these conditions, individuals need to consult with healthcare professionals before using the medication to ensure its suitability and safety in their specific case


What is Fildena, and what is it used for?

Fildena is a pharmaceutical product containing sildenafil citrate and is primarily used for the treatment of erectile dysfunction (ED) in men. It helps in achieving and maintaining erections during sexual activity.

How does Fildena work to treat erectile dysfunction?

Fildena works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). This inhibition allows for the accumulation of cyclic guanosine monophosphate (cGMP), promoting smooth muscle relaxation in the penile arteries. The relaxed muscles facilitate increased blood flow to the erectile tissues, leading to an erection.

What is the role of sildenafil citrate in Fildena?

Sildenafil citrate is the active ingredient in Fildena. It acts as a PDE5 inhibitor, preventing the breakdown of cGMP. This, in turn, enhances the vasodilatory effects of nitric oxide, promoting improved blood flow to the penis.

Can Fildena be used for conditions other than erectile dysfunction?

Yes, besides treating ED, Fildena, or sildenafil citrate, is also used to manage pulmonary arterial hypertension (PAH). In PAH, Fildena works by relaxing the smooth muscles in the pulmonary arteries, reducing resistance and improving blood flow to the lungs.

How long does it take for Fildena to start working?

The onset of action for Fildena varies among individuals but is generally around 30 minutes to an hour after consumption. It is advisable to take the medication on an empty stomach for faster absorption.

How long does the effect of Fildena last?

The duration of Fildena’s effect can last up to four to six hours. However, individual responses may vary, and the effectiveness may be influenced by factors such as age, overall health, and dosage.
