1. Vardenafil was initially a co-marketing arrangement between three pharmaceutical companies - Bayer, GSK (GlaxoSmithKline) and Schering Plough (today part of Merck and Co.) - under the trade name . GSK returned co-promotion rights to Bayer in many territories outside the USA. Two companies sell Vardenafil in Italy under two different brand names -(Bayer) and Vivanza (GSK).
2. Vardenafil, known under the brand name is a prescription medication for male erectile dysfunctiontreatment. It belongs to a class of drugs called PDE5 inhibitors. increases blood flow to the penis, which helps gain and sustain an erection during sex. active ingredient works on the chain of reactions within the penis during arousal, when the corpus cavernosa (two large chambers) in the male's penis fills with blood, resulting in an erection.A penile erection happens when the penis fills with blood. This occurs when the blood vessels that supply the penis with blood expand (dilate), and the vessels that take blood away from the penis contract, resulting in an accumulation of blood in the penis.
Beyond its indications for erectile dysfunction, Vardenafil may be effective in the treatment of premature ejaculation, and it may significantly increase the time from vaginal penetration to ejaculation.
Vardenafil, as with all PDE5 inhibitors, should not be used by men taking nitrate medications, because combining them with Vardenafil might provoke potentially life-threatening hypotension (low blood pressure).
Further, Vardenafil lengthens the QT interval. Therefore it should not be taken by men taking other medications that affect the QT interval (such as Amiodarone).
