Fildena Professional contains sildenafil citrate, which primarily acts on the blood vessels of the penis to treat erectile dysfunction (ED). Here’s how it works in the body: Target tissue: Sildenafil inhibits the enzyme phosphodiesterase type 5 (PDE5) in the smooth muscle of the penile corpus cavernosum. This inhibition increases cyclic GMP (cGMP) levels, which relaxes the smooth muscle and allows more blood flow into the penis during sexual stimulation. Effect: Increased blood flow causes the penis to become erect when sexually aroused. It does not directly stimulate sexual Fildena Professional sexual stimulation is still required for the medication to work. Secondary effects: Sildenafil can cause mild relaxation of blood vessels elsewhere, sometimes leading to flushing, headache, or nasal congestion. It does not act on the brain or hormonal system directly, so its main site of action is vascular and localized to erectile tissue. Duration and metabolism: Onset: 30–60 minutes, depending on food intake and metabolism. Active effects last 4–6 hours before the body metabolizes and eliminates it through the liver and kidneys. In short, Fildena Professional acts mainly in the penile blood vessels to enable erections, with mild systemic vascular effects elsewhere.
