Vidalista, containing the active ingredient Tadalafil, is a popular medication used to treat Erectile disorder. It belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. Tadalafil works by blocking the PDE5 enzyme, which increases the levels of a chemical called cyclic guanosine monophosphate (cGMP). This leads to relaxation of the smooth muscles in the blood vessels of the penis, allowing for increased blood flow and helping men achieve and maintain an erection. https://www.flatmeds.com/product/vidalista/
