Filitra 40 mg is a medication used to treat erectile dysfunction (ED) in men. It contains vardenafil, a PDE5 inhibitor that works by increasing blood flow to the pill helping men achieve and maintain an erection during sexual activity when sexually aroused. Vardenafil, the active ingredient in Filitra 40 mg, works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). Normally, PDE5 breaks down cGMP (cyclic guanosine monophosphate), which is a molecule responsible for relaxing smooth muscles and dilating blood vessels in the pill. By blocking PDE5, Filitra 40 mg increases the levels of cGMP, leading to improved blood flow and helping a man achieve and maintain an erection during sexual stimulation. https://www.genericday.com/filitra-40-mg.html
