Ready to combat ED confused, but what type of PDE-5 inhibitor to take? Those Äôre not alone. Of the 3 FDA approved PDE-5 inhibitors, Viagra (sildenafil citrate) is definitely the most popular, but popularity alone should not have, AOT is the determining factor.

At high levels of cGMP are present, the penile arteries relaxed and natural and hard erection occurs.

Unfortunately, most men with ED, PDE-5 enzyme neutralizes any available cGMP and without cGMP an erection will be slack, or not at all. That AOS to PDE-5 inhibitors like Viagra, Cialis and Levitra These drugs come in. “defend” or block the unwanted PDE-5, and so very wanted cGMP is allowed to remain in the penis after sexual stimulation, and thus help the erection process and keeping the penis erect.
