Vidalista 5 mg contains Tadalafil, a medication that works by blocking the enzyme PDE5 (phosphodiesterase type 5). This enzyme usually breaks down cGMP (cyclic guanosine monophosphate), a molecule that helps relax the muscles and widen blood vessels in the penis. By inhibiting PDE5, Tadalafil allows cGMP to remain active longer, promoting better blood flow to the penis and helping men achieve and maintain an erection when sexually stimulated. https://www.genericday.com/vidalista-5-mg.html
