description:

vardenafil is an oral drug that is used to treat impotence, the inability to attain or maintain a penile erection. 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.

vardenafil (inn) is a pde5 inhibitor used for treating erectile dysfunction. vardenafil'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). the difference between the vardenafil 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 vardenafil. vardenafil's relatively short effective time is comparable to but somewhat longer than sildenafil's.

applications:
?vardenafil relaxes muscles and increases blood flow to particular areas of the body. vardenafil is used

to treat erectile dysfunction (impotence). vardenafil may also be used for purposes not listed in this

medication guide.beyond its indications for erectile dysfunction, vardenafil may be effective in the treatment of premature ejaculation, where 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 causing lengthening of the qt interval. therefore

it should not be taken by men taking other medications that affect the qt interval (such as amiodarone).

adverse drug reactions:
the common, adverse drug reactions (side-effects) are the same as with other pde5 inhibitors. the frequent vardenafil-specific side-effect is nausea; the infrequent side-effects are abdominal pain,

back pain, photosensitivity, abnormal vision, eye pain, facial edema, hypotension, palpitation, tachycardia, arthralgia, myalgia, rash, itch, and priapism.
