No.  Viagra is part of a class of drugs known, as we discussed above, as PDE-5 drugs called phosphodiesterase-5  inhibitors.  Others are similar drugs, many of which you have seen in an estimated 6 zillion television commercials, including Cialis (tadalafil), Levitra (vardenafil), Revatio (sildenafil), Adcirca (tadalafil), and Staxyn (vardenafil).   So if you buy into the "PDE-5A inhibitors is the problem here" all of these drugs could potentially be implicated.
