Filitra 20 mg is a generic medication containing vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction (ED) in men. It enhances blood flow to the pill during sexual arousal, aiding in achieving and maintaining an erection. Vardenafil works by inhibiting the PDE5 enzyme, which breaks down cyclic GMP—a molecule that helps relax smooth muscles and dilate blood vessels in the pill. By blocking PDE5, vardenafil maintains higher levels of cyclic GMP, promoting increased blood flow during sexual stimulation. https://www.genericday.com/filitra-20-mg.html
