Generic Levitra was co-marketed by Bayer Pharmaceuticals, GSK, and SP 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 Generic Levitra 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.
This medicine's indications and contra-indications are the same as with other PDE5 inhibitors; it is closely related in function to sildenafil citrate (Viagra) and tadalafil (Cialis). Structurally, the difference between the Levitra molecule and sildenafil citrate is a nitrogen atom's position and the change of sildenafil's piperazine ring methyl group to an ethyl group. Tadalafil is structurally different from both sildenafil and Brand Levitra. Vardenafil's relatively short effective time is comparable to but somewhat longer than sildenafil's.
Vardenafil, as with all PDE5 inhibitors, should not be used by men taking nitrate medications, because combining them with Levitra might provoke potentially life-threatening hypotension (low blood pressure).
