PDE 5 inhibitor
is the abbreviation for phosphodiesterase type 5 inhibitor.
PDE 5 inhibitor prevents normal PDE 5 from breaking
down cGMP. Men can then have longer-lasting, more rigid
erections. Common PDE 5 inhibitors are as sildenafil,
varendafil, and tadalafil and are trademarked respectively
as Viagra, Levitra, and Cialis. PDE 5 inhibitors can
help men who have undergone prostate cancer treatment
and experience impotence as a result. PDE inhibitors,
however, will not help patients unless they become sexually
aroused.
