Fildena Super Active works by inhibiting the phosphodiesterase type 5 (PDE5) enzyme, which is responsible for breaking down cyclic GMP in the body. Cyclic GMP is a molecule that relaxes the smooth muscle and dilates blood vessels, enabling blood to flow to the penis. By blocking PDE5, Fildena Super Active helps increase the levels of cyclic GMP, improving blood flow and helping men achieve an erection in response to sexual stimulation. https://www.genericday.com/fildena-super-active.html
