Fildena Double 200 mg is a higher-strength medication used to treat erectile dysfunction (ED) in men. It contains Sildenafil Citrate, the same active ingredient found in Viagra and other Fildena products, but at a much stronger dose. Fildena Double 200 mg works by inhibiting phosphodiesterase type 5 (PDE5), an enzyme that breaks down cGMP, which is important for relaxing the muscles in the blood vessels of the penis. This leads to increased blood flow, helping a man achieve and maintain an erection during sexual activity. https://www.flatmeds.com/product/fildena-double-200-mg/
