Brief History of Vardenafil :
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 and Canada.
Treatment of ED:
Vardenafils 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). The difference between the vardenafil molecule and sildenafil citrate is a nitrogen atoms position and the change of sildenafils piperazine ring methyl group to an ethyl group. Tadalafil is structurally different from both sildenafil and vardenafil. Vardenafils relatively short effective time is comparable to but somewhat longer than sildenafils.
Beyond its indications for erectile dysfunction, vardenafil may be effective in the treatment of premature ejaculation, where it may significantly increase the time from penetration to ejaculation.
Function of Vardenafil:
It has a mechanism of action that is similar to sildenafil (Viagra), and tadalafil (Cialis). Penile erection is caused by the engorgement of the penis with blood. This engorgement occurs when the blood vessels delivering blood to the penis increase in size and increase the delivery of blood to the penis. At the same time, the blood vessels carrying blood away from the penis decrease in size and decrease the removal of blood from the penis. Sexual stimulation that leads to the engorgement and erection causes the production and release of nitric oxide in the penis. Nitric oxide then activates the enzyme, guanylate cyclase to produce cyclic guanosine monophosphate (cGMP). The cGMP is primarily responsible for increasing and decreasing the size of the blood vessels carrying blood to and from the penis, respectively. Vardenafil prevents an enzyme called phosphodiesterase-5 (PDE-5) from destroying cGMP so that cGMP persists longer. The longer cGMP persists, the more prolonged the engorgement of the penis. Vardenafil was approved by the FDA in August 2003.
This medication is a highly effective treatment for erectile dysfunction (impotence) in men. However, it is not meant for everyone. Here are a few warnings to consider before taking Levitra:
Do not take this drug if you are being treated with other medications that contain nitrates
Do not use this medication if you suffer from retinitis pigmentosa
Avoid this product it if you are allergic to vardenafil or any other ingredients in this medicine
Do not use if you have a history of severe heart, kidney and liver problems

Avoid if you have non-arteritic anterior ischaemic optic neuropathy (NAION)
Do not use if you have a condition that causes bleeding such as a stomach ulcer
Do not consume if you have sickle cell disease, bone cancer or leukaemia.
Possible Side Effects:
Levitra tablets are not known to have any serious side effects and, as a matter of fact, they probably exhibit the least negative side effects when compared to any other erectile dysfunction treatment. Mild side effects may include dizziness, facial flushing, blocked nose, nausea, impaired vision and upset stomach. If experienced, these side effects should subside within a few hours. Major side effects such as erections that last more than 4 hours, temporary vision loss or impairment of hearing are very rare. If you ever experience such effects, you need to report these immediately to a doctor.
