Fildena 25 mg is a medication used to treat erectile dysfunction (ED) in men. It contains Sildenafil Citrate, the same active ingredient found in Viagra. Fildena 25 mg works by increasing blood flow to the penis, helping men with ED achieve and maintain an erection when sexually stimulated. Sildenafil Citrate, the active ingredient in Fildena, works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). PDE5 normally breaks down cyclic GMP, a molecule that helps relax the smooth muscles and dilate blood vessels in the penis.
