Tazzle 20 mg is a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient tadalafil, which belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. Tadalafil works by inhibiting the enzyme phosphodiesterase-5 (PDE5), which is responsible for the degradation of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells. By inhibiting PDE5, tadalafil increases the levels of cGMP, leading to relaxation of the smooth muscles and increased blood flow to the during stimulation. This helps men achieve and maintain an erection. https://www.genericday.com/tazzle-20-mg.html
