These ED pills work by relaxing penile muscles which in turn increases blood flow in the penis and helps in getting an erection.

These pills are phosphodiesterase type 5 inhibitors and restrict the degradation of cGMP (cyclic guanosine monophosphate)in the corpus cavernosum surrounding the penis. This cGMP is responsible for smooth muscle relaxation of the corpus cavernosum.On sensual stimulation, nitric oxide release from the endothelial cells and nerve terminals of the corpus cavernosum and binds to the cGMP receptors which results in increased production of cGMP.The increased level of cGMP leads to relaxation of penile muscles which in turn increase vasodilation and increased blood flow in the penis and helps in getting and maintaining a firm erection on sensual stimulation.

One thing should be noted that these pills only work on sensual stimulation. In the absence of stimulation, these pills will not be effective.
