Fildena is a brand name for a medication used to treat erectile dysfunction (ED) in men. The active ingredient in Fildena is Sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. Sildenafil works by increasing blood flow to the penile when a man is sexually aroused, enabling him to achieve and maintain an erection. Fildena is primarily prescribed to men who have difficulty getting or maintaining an erection sufficient for sexual activity. It is not a cure for ED but can help improve erectile function when used as directed. https://www.genericday.com/fildena-100-mg.html
