Tadacip 20 mg works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). PDE5 typically breaks down cGMP, a molecule that plays a crucial role in relaxing the smooth muscles of blood vessels. By blocking PDE5, tadalafil helps increase the levels of cGMP, leading to the relaxation of smooth muscle and increased blood flow to the penis, which is essential for achieving an erection.
