Vardenafil, also known by the brand name Levitra, is a prescription medication that treats male erectile dysfunction. Erectile dysfunction is when a man is unable to get or sustain an erection. ... Its action is similar to that of sildenafil, or Viagra, but Viagra lasts between 2 and 4 hours, while Levitra lasts 4 hours.
Vardenafil was co-marketed by Bayer Pharmaceuticals, GlaxoSmithKline, and Schering-Plough under the trade name Levitra. As of 2005, the co-promotion rights of GSK on Levitra have been returned to Bayer in many markets outside the U.S. In Italy, Bayer sells vardenafil as Levitra and GSK sells it as Vivanza. Thus, because of European Union trade rules, parallel imports might result in Vivanza sold next to Levitra in the EU.
An orally disintegrating form, marketed as Staxyn and Levitra Soft, has been gaining approvals in countries such as the United States[1]and Canada.[2]
