Start a discussion cialis liquid Viagra (sildenafil) belongs to a class of medications, known as phosphodiesterase inhibitors, which are indicated for the treatment of erectile dysfunction in men. Other phosphodiesterase inhibitors include Levitra (vardenafil) and Cialis (tadalafil). These medications are not necessarily different types of Viagra, but treatment alternatives. Viagra, commonly referred to as the "little blue pill" was the first erectile dysfunction medication to be approved by the U.S. Food and Drug Administration (FDA). By inhibiting phosphodiesterase, Viagra enhances the effect of nitric oxide allowing for smooth muscle relaxation and increasing blood flow to specific areas of the body in the presence of sexual arousal or stimulation. Viagra exhibits no therapeutic responses in the absence of sexual stimulation. Possible side effects associated with treatment with Viagra include flushed skin, nausea or abdominal pain, congestion in the nose, diarrhea, vision clouded with a blue tint, headache and digestive problems.Dizziness 3% 4% 3% 2%
