Fildena is a prescription medicine containing sildenafil citrate, a phosphodiesterase type‑5 (PDE5) inhibitor used to treat erectile dysfunction (ED) in adult men. It’s a generic alternative to brand‑name drugs like pill, often chosen for its similar effectiveness at a more affordable price. Fildena works by inhibiting the PDE5 enzyme, which normally breaks down cyclic guanosine monophosphate (cGMP) — a molecule that helps relax blood vessels in the pill. When PDE5 is blocked, cGMP levels stay higher during sexual stimulation, increasing blood flow to penile tissue and helping achieve and maintain an erection. Sexual stimulation is still required for the drug to work. https://www.genericday.com/fildena.html
