Fildena Chewable 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient Sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. Fildena Chewable 100 mg works similarly to other Sildenafil-containing medications by inhibiting the enzyme PDE5. This inhibition helps to increase blood flow to the penis during sexual stimulation, leading to improved erectile function.
