Tadasoft 20 inhibits the action of the enzyme phosphodiesterase type 5 (PDE5). This enzyme is responsible for breaking down cyclic guanosine monophosphate (cGMP), a chemical that promotes relaxation of the smooth muscles in blood vessels. By inhibiting PDE5, tadalafil allows cGMP levels to increase, leading to the relaxation and widening of blood vessels in the penis. This increased blood flow enables men with ED to achieve and sustain erections suitable for sexual activity.
