Fildena 150 is a generic form of Sildenafil Citrate, which is an active ingredient that boosts blood flow to the penis during sexual stimulation. It works by blocking the action of a special enzyme called PDE 5.

It also prevents the breakdown of cGMP, which is an important substance that allows blood to flow to the penis.

During sexual stimulation, nitric oxide is released into the penis and interacts with the haem group of soluble guanylate cyclase (sGC), which is responsible for the contraction and dilation of blood vessels. During sexual stimulation, sGC also stimulates the production of cGMP, which is necessary for sustaining an erection during intercourse.

Fildena 200 is available in tablet forms that should be taken once a day at regular intervals. It is best to consume it on an empty stomach, as fatty meals can delay its effect.

It is advisable to consult with an ED specialist before starting this medication. It is also important to avoid certain foods, beverages, and activities while taking it.
