Fildena Chewable 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate as its active ingredient, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Fildena Chewable 100 mg works by increasing blood flow to the penis during sexual stimulation, thereby helping men achieve and maintain an erection. Clinical studies have shown that sildenafil citrate is effective in treating ED and helping men achieve erections sufficient for sexual activity. However, it's important to note that sildenafil citrate does not cure ED or increase sexual desire; it only helps facilitate the erectile response when sexual stimulation occurs.
