About Sildenafil  

Sildenafil medicines which are the unbranded version of Viagra medicines are used for managing erection difficulties in men. Another branded version of Sildenafil medicine known as Revatio is prescribed for treating the symptoms of pulmonary arterial hypertension (PAH).

For treating erectile dysfunction, the medicine relaxes the blood vessels of the penile and boosts the blood flow through them. The increase in the blood flow to the penile helps restore the erection function and it triggers stronger erections.

In the case of PAH, the medicine relieves the pain, inflammation, and discomfort felt in the lungs because of the increased blood pressure. The medicines ease the blood flow in the lungs by causing vasodilation.

The dose for managing both these conditions will be decided by the healthcare provider. The dosage will be based on several factors like age, gender, severity, health conditions, allergies, etc.

Sildenafil medicine active ingredient

The active ingredient of Sildenafil medicine is Sildenafil Citrate. This component is classified under the category of phosphodiesterase type 5 (PDE5) inhibitor drugs. Sildenafil citrate is the key ingredient of these medicines as it dilates the blood vessels and eases the blood flow through them.

The function of the active ingredient is to expand the blood vessels by relaxing the muscles. The relaxation of the blood vessels helps overcome their narrowing and constrictions. This causes their widening and blood flow happens more efficiently.

In addition to the active ingredient, Sildenafil medicines consist of several inactive ingredients such as microcrystalline cellulose, magnesium stearate, anhydrous dibasic calcium phosphate, croscarmellose sodium, hypromellose, titanium dioxide, lactose, triacetin, and FD & C Blue #2 aluminum lake.

How does Sildenafil treat erectile dysfunction?

The active ingredient of Sildenafil medications is a PDE5 inhibitor compound. It suppresses the action of PDE5 enzymes in the walls of the penile blood vessels. By inhibiting PDE5 enzymes, the medicine prevents the buildup of plaque in the passages of the penile blood vessels.

PDE5 enzymes are present in the smooth muscle cells of the walls of the penile blood vessels. They contribute to the narrowing of the blood vessels. This limits the circulation of blood to the penile. However, the medicine conducts vasodilation in the penile.

Vasodilation boosts the blood flow through the passages of the blood vessels. Consequently, the blood supply to the penile increases, and the erection function gets restored for some time. The increase in blood flow improves the ability to get and sustain harder erections.

Sildenafil alternatives

Sildenafil has many generic versions. One of them is Fildena 100mg. These are high-dose medicines that help manage moderate to severe forms of erection difficulties. In the presence of arousal, they dilate the penile blood vessels and allow more blood flow to the penile.

Without arousal, ED medicine fails to deliver its required action, since they do not trigger erections spontaneously.
