Mechanism of action
Tadalafil belongs to the group of phosphodiesterase type 5 inhibitors (PDE-5). It blocks the action of the enzyme PDE-5, which destroys cyclic guanosine monophosphate (cGMP). As a result, cGMP accumulates in the cavernous bodies of the penis, which leads to relaxation of smooth muscles and increased blood flow to the penis.
