Fildena 50 mg is a medication used to treat erectile dysfunction (ED) in men. Its active ingredient is Sildenafil Citrate, a phosphodiesterase type 5 (PDE5) inhibitor that helps improve blood flow to the penis during sexual stimulation, enabling an erection. Sildenafil in Fildena 50 mg works by blocking the PDE5 enzyme, which regulates blood flow in the penis. Sexual arousal triggers an increase in cyclic guanosine monophosphate (cGMP), relaxing smooth muscles and dilating blood vessels.
