Vardenafil (Levitra) ---Description:
Vardenafil (Levitra) works by helping to relax muscles and increase blood flow into the penis during sexual stimulation. This helps men to achieve and maintain an erection. Levitra is used to treat erectile dysfunction (impotence). Do not take Vardenafil (Levitra) if you are also using a nitrate drug for chest pain
or heart problems (such as nitroglycerin).
During sexual activity, if you become dizzy or nauseated, or have pain, numbness, or tingling in your chest, arms, neck, or jaw, stop and call your doctor right away.
You could be having a serious side effect of Levitra. Contact your doctor or seek emergency medical
attention if your erection is painful or lasts longer than 4 hours. A prolonged erection (priapism) can
damage the penis.
Vardenafil (Levitra)--- is a PDE5 inhibitor used for treating erectile dysfunction.Vardenafil (Levitra)'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.
