Tadalista 40 mg is a high-strength erectile dysfunction (ED) medication that contains 40 mg of tadalafil, a long-acting PDE5 inhibitor. It is primarily intended for men with moderate to severe ED who have not responded adequately to lower doses such as 10 mg or 20 mg. Tadalafil works by inhibiting the PDE5 enzyme, which increases levels of cGMP in the penile tissue. This results in relaxed blood vessels and improved blood flow to the penis during sexual stimulation, enabling a firmer, longer-lasting erection. https://www.genericday.com/tadalista-40-mg.html
