Yes No Report as inappropriate viagra 25mg 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.Using oral drugs properly
On October 6, 2011, the U.S. FDA approved tadalafil [15] to treat the signs and symptoms of benign prostatic hyperplasia (BPH). BPH is a condition in males in which the prostate gland becomes enlarged, obstructing the free flow of urine. Symptoms may include sudden urges to urinate (urgency), difficulty in starting urination (hesitancy), a weak urine stream, and more frequent urination- especially at night. The FDA has also approved tadalafil for treatment of both BPH and erectile dysfunction (ED) where the two conditions co-exist.

For once-a-day evaluation of tadalafil at doses of 2.5, 5, and 10 mg 3 clinical studies were initially conducted involving 853 patients of various ages (range 21-82 years) and ethnicities, with erectile dysfunction of various severities (mild, moderate, severe) and etiologies. In the two primary efficacy studies of general populations, the mean per-subject proportion of successful intercourse attempts were 57 and 67% on CIALIS 5mg, 50% on CIALIS 2.5mg as compared to 31 and 37% with placebo. In the study in patients with erectile dysfunction secondary to diabetes, the mean per-subject proportion of successful attempts were 41 and 46% on CIALIS 5mg and 2.5mg, respectively, as compared to 28% with placebo. Most patients in these three studies were responders to previous on-demand treatment with PDE5 inhibitors. In a subsequent study, 217 patients who were treatment-naive to PDE5 inhibitors were randomised to CIALIS 5mg once a day vs. placebo. The mean per-subject proportion of successful sexual intercourse attempts was 68% for CIALIS patients compared to 52% for patients on placebo.Deje de usar vardenafil y llame de inmediato a su médico si usted tiene:
