CONSIDERATIONS TO KNOW ABOUT VIAGRA

Sildenafil is often a potent and selective inhibitor of cGMP-certain phosphodiesterase form 5 (PDE5), which can be answerable for degradation of cGMP in the corpus cavernosum. The molecular structure of sildenafil is analogous to that of cGMP and functions for a aggressive binding agent of PDE5 during the corpus cavernosum, resulting in additional
