Vidalista 20 is a medication commonly used to treat erectile dysfunction. It contains the active ingredient Tadalafil, which is classified as a phosphodiesterase type 5 (PDE5) inhibitor. PDE5 inhibitors work by blocking the enzyme that typically degrades cyclic guanosine monophosphate (cGMP), a substance that helps relax the blood vessels in the penis, thereby promoting increased blood flow.
