Avanafil is a phosphodiesterase (PDE) inhibitor that brings about type 5-mediated metabolism of cyclic guanosine monophosphate (cGMP) in the corpus cavernosum, which is responsible for the smooth muscle relaxation due to increased cGMP levels and sexual stimulation by increasing inflow of blood into the corpus cavernosum of the penis, thereby producing an erection. In the absence of sexual stimulation, this drug will not initiate its effect.
