Fildena 50 mg is a medication containing sildenafil citrate, a phosphodiesterase type-5 (PDE-5) inhibitor, used to treat erectile dysfunction (ED) in men. Sildenafil works by enhancing the effects of nitric oxide, which relaxes smooth muscles in the penis and increases blood flow during sexual stimulation, enabling a firm erection sufficient for sexual activity. The 50 mg dose is a standard starting dose for many men and can be adjusted up or down based on effectiveness and tolerance.
