Currently, there have been no head-to-head trials comparing effectiveness of the three drugs. A fourth oral erectile-dysfunction drug, apomorphine (Uprima®, TAP Pharmaceuticals), has been approved in Europe, and TAP Pharmaceuticals applied to the FDA for its approval at the end of 2002. It is a dopamine receptor agonist and works through an entirely different mechanism. Although the drug received the support of an FDA advisory panel in April 2000 (as reported by heartwire ), TAP Pharmaceuticals withdrew apomorphine's new drug application soon after, due to concerns that it caused fainting spells. It resubmitted the drug late last year after further studies.

Proportion of vardenafil subjects with a 50% or greater decrease from baseline in mean sperm concentration at 6 months (LOCF), compared to placebo after repeated usedate_rangeTime Frame:24 weeksenhanced_encryptionyesSafety Issue: Mean sperm concentrationdate_rangeTime Frame:24 weeksenhanced_encryptionyesSafety Issue: Mean sperm countdate_rangeTime Frame:24 weeksenhanced_encryptionyesSafety Issue: Proportion of sildenafil subjects with a 50% or greater decrease from baseline in mean sperm concentration at 6 months (LOCF), compared to placebo and vardenafil after repeated usedate_rangeTime Frame:24 weeksenhanced_encryptionyesSafety Issue: Washington, DC - The FDA gave approval yesterday to vardenafil (Levitra®, Bayer and Glaxo Smith Kline), an oral erectile-dysfunction drug that works through the same mechanism as sildenafil (Viagra®, Pfizer). Like sildenafil, vardenafil can seriously affect blood pressure and should not be taken by those on alpha blockers or nitrates.
The recommended dose is 10 mg taken one hour before sexual activity, with 20-, 5.0-, and 2.5-mg doses available. Vardenafil is a phosphodiesterase inhibitor and, like sildenafil, is strongly contraindicated if patients are taking nitrates (nitroglycerin tablets or patches) or alpha blockers, due to the possibility of a steep drop in blood pressure. Patients with QT prolongation are also advised not to take the drug, as there is a possibility of abnormal heart rhythm in these patients. The FDA warns that men whose underlying cardiovascular status makes sexual activity inadvisable should not take vardenafil. Patients who have suffered an MI or stroke within the last six months or have hypotension or hypertension, unstable angina, severe liver impairment, end-stage renal disease requiring dialysis, or retinitis pigmentosa should not take the drug.
"Today's approval of Levitra means there is now an important alternative in the treatment of erectile dysfunction," said Colin J Foster, president, Bayer Pharmaceuticals Corporation, in a press release. The drug will be comarketed by Glaxo Smith Kline and Bayer, and Bloomberg News reports packaging will feature the "Levitra flame" levitra 20 brand to help distinguish the round orange pills from Viagra's now-famous blue diamond-shaped ones. Both drugs are likely to soon have a third competitor stateside. Eli Lilly & Co and Icos Corporation intend to introduce tadalafil (Cialis®), another phosphodiesterase inhibitor, to the US market later this year. Tadalafil and vardenafil have both been approved in Europe. The recommended dose is 10 mg taken one hour before sexual activity, with 20-, 5.0-, and 2.5-mg doses available. Vardenafil is a phosphodiesterase inhibitor and, like sildenafil, is strongly contraindicated if patients are taking nitrates (nitroglycerin tablets or patches) or alpha blockers, due to the possibility of a steep drop in blood pressure.
