Vardenafil Technical Information
This section includes technical information about Levitra (vardenafil), the class of drug that it is and how it works.
The active ingredient in the Levitra tablet is a compound called vardenafil. Vardenafil works by inhibiting phosphodiesterase type 5 (PDE5) and is used in the treatment of erectile dysfunction. It can help around 70% of men to achieve and maintain an erection during sexual activity. It is commonly marketed under the trade name Levitra or less often under the name Vivanza.
Vardenafil is closely related in both function and marketing to sildenafil (Viagra) and tadalafil (Cialis). Structurally, the vardenafil molecule differs from sildenafil by only a methyl group and the position of one nitrogen atom in its structure. It has a relatively short effective time, making it more similar to sildenafil than tadalafil.
The Formal Chemical Name (IUPAC) is:
2-(2-ethoxy-5-(4-ethylpiperazin-1-ylsulfonyl)phenyl)-5-methyl-7-propylimidazo[1,5-f][1,2,4]triazin-4(1H)-one
