Tadalis SX 20 MG works by inhibiting the action of the phosphodiesterase type 5 (PDE5) enzyme. This enzyme restricts blood flow to the penis by breaking down cyclic guanosine monophosphate (cGMP), which helps relax the smooth muscles in the blood vessels. By inhibiting PDE5, Tadalafil allows cGMP to accumulate, leading to smoother muscle relaxation and increased blood flow to the penis.
