Levitra
Vardenafil is a prescription drug used in the treatment of male erectile dysfunction. It can assist men with this disorder in achieving and maintaining an erection during sexual activity. It should not be used with types of medicines called nitrates and alpha-blockers because of potentially dangerous interactions with these drugs. TV ads for the drug also warn that in the event an erection lasts for more than four hours, a condition known as priapism, that medical advice should be sought immediately.
Vardenafil is co-marketed by Bayer Pharmaceuticals and GlaxoSmithKline under the trade name Levitra® . It is available by prescription in tablet form.
