Fildena 100 is a popular medication used to treat erectile dysfunction in men. It contains the active ingredient sildenafil citrate, which works by increasing blood flow to the penis, allowing for a stronger and longer-lasting erection. But how exactly does Fildena 100 work? In this blog post, we will delve into the science behind this medication and explore its mechanism of action.

To understand how Fildena 100 works, it is important to first understand the physiological process of an erection. When a man is sexually aroused, the arteries in the penis relax and widen, allowing for increased blood flow. This increased blood flow fills the spongy tissue in the penis, causing it to become erect. However, in men with erectile dysfunction, this process is disrupted, leading to difficulties in achieving and maintaining an erection.

Sildenafil citrate, the active ingredient in Fildena 100, belongs to a class of medications known as phosphodiesterase type 5 (PDE5) inhibitors. PDE5 is an enzyme that breaks down cyclic guanosine monophosphate (cGMP), a molecule that is responsible for relaxing the smooth muscles in the penis and increasing blood flow. By inhibiting PDE5, sildenafil citrate allows cGMP to accumulate, leading to improved blood flow to the penis and a stronger erection.

When a man takes Fildena 100, the medication is rapidly absorbed into the bloodstream and reaches peak concentrations within 30 to 120 minutes. Once in the body, sildenafil citrate selectively inhibits PDE5, allowing cGMP levels to rise and promoting smooth muscle relaxation in the penis. This results in improved blood flow to the erectile tissue, leading to a firm and sustainable erection.

It is important to note that Fildena 100 does not cause an erection on its own. Sexual stimulation is still required to activate the release of nitric oxide, a chemical that triggers the production of cGMP. Without sexual arousal, Fildena 100 will not be effective in producing an erection.

In conclusion, Fildena 100 works by inhibiting the enzyme PDE5, allowing for increased levels of cGMP and improved blood flow to the penis. This mechanism of action helps men with erectile dysfunction achieve and maintain a satisfactory erection during sexual activity. If you are considering using Fildena 100 for erectile dysfunction, it is important to consult with a healthcare provider to determine if this medication is right for you.
