Viagra will soon get competition from Levitra and Cialis.
Levitra just came out in the U.S...and will be out mid-October in Canada. Cialis will be available later in both Canada and the U.S.
These drugs all work the same...they block phosphodiesterase-5 enzymes, cause vasodilation, and increase blood flow to the penis.
