Fildena Chewable 100 mg is a variant of Sildenafil Citrate, the same active ingredient found in Viagra, designed to treat erectile dysfunction (ED) in men. This formulation comes in a chewable tablet form, making it easier to take for those who may have difficulty swallowing pills. Like other Sildenafil-based medications, Fildena Chewable 100 mg works by inhibiting the PDE5 enzyme. This enzyme normally restricts blood flow to the penis, and by blocking its action, Sildenafil promotes increased blood flow to the penis during sexual arousal, allowing for a firm erection.
