Who can explain how Fildena 25 mg works?

Fildena 25 mg is a brand name for sildenafil citrate, a medicine most commonly prescribed to adult men for erectile dysfunction (ED). It works by helping improve blood flow, but it does not create sexual desire on its own. Inside the body, an enzyme called phosphodiesterase type-5 (PDE5) can reduce blood flow by breaking down a chemical messenger known as cGMP. cGMP is important because it relaxes smooth muscles in blood vessel Fildena 25 mg  . Fildena blocks the PDE5 enzyme, allowing cGMP levels to stay higher for longer. As a result, blood vessels relax and widen, leading to improved blood circulation in specific tissues. When a person is already sexually stimulated, this increased blood flow helps support a natural physical response. Without stimulation, the medicine has little or no effect. This is why Fildena 25 mg is not considered an aphrodisiac. The 25 mg strength is a low dose, often prescribed when starting treatment or for people who are sensitive to medications. Like all prescription medicines, Fildena should only be used under medical supervision, as it can interact with other drugs and may cause side effects such as headache, flushing, or dizziness.
