Fildena 200 is a high-strength medication used to treat erectile dysfunction (ED) in men. It contains Sildenafil Citrate, the same active ingredient found in Viagra, which belongs to the PDE5 (phosphodiesterase type 5) inhibitor class of drugs. Fildena helps men achieve and maintain a firm erection by enhancing blood flow to the penile region when sexually stimulated. It is one of the strongest doses available and is usually recommended for men with severe ED who do not respond to lower doses.
