Filitra is a brand of medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient Vardenafil, which is a phosphodiesterase type 5 (PDE5) inhibitor. Like other PDE5 inhibitors, Filitra works by increasing blood flow to the penis during sexual stimulation, enabling men to achieve and maintain erections. Vardenafil, the active ingredient in Filitra, inhibits the PDE5 enzyme, leading to increased levels of cyclic guanosine monophosphate (cGMP). Elevated cGMP levels relax the smooth muscles in the blood vessels of the penis, allowing enhanced blood flow and promoting erections when sexually aroused. Filitra is taken orally, usually about 30 minutes to an hour before sexual activity. Sexual stimulation is necessary for its effects to work; the medication doesn't cause automatic erections. https://www.genericday.com/filitra-20-mg.html
