Tadalafil works similarly to other PDE5 inhibitors, such as sildenafil (Viagra), by blocking the action of the enzyme phosphodiesterase type 5 (PDE5). This inhibition increases levels of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the penis. Elevated cGMP levels lead to relaxation of the blood vessels in the penis, allowing for increased blood flow and facilitating erections during sexual stimulation.
