Application
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.
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.
It is available in 2.5 mg, 5 mg, 10 mg, and 20 mg doses in round orange tablets. The normal starting dose is 10 mg (roughly equivalent to 50 mg of sildenafil). Vardenafil should be taken 1 to 2 hours prior to sexual activity, with a maximum dose frequency of once per day. In some territories, such as the UK, only certain doses may be available.
Vardenafil is also available under the name Staxyn as a tablet which dissolves on the tongue rather than being swallowed in the form of a pill.
The recommended dosage of Staxyn is one 10 mg tablet taken 60 minutes before sexual activity. Certain antidepressants, antifungal, antibiotic, heart, and blood pressure medications can interact with Staxyn. Tell your doctor all medications you use.
Vardenafil is a drug for erectile dysfunction in men and is the first-line treatment for erectile dysfunction. Developed by the German company Bayer, it was first listed in the United States in 2002. Like sildenafil, it belongs to the second generation of type 5 phosphodiesterase inhibitors, and the onset of action is very rapid, about 15~20 minutes. The effect is ten times stronger than sildenafil. Clinical data show that 50%~60% of male diabetic patients over 50 years old suffer from erectile dysfunction, and erectile dysfunction caused by nerve and vascular damage caused by diabetes is particularly difficult to treat. Bayer's potent and selective phosphodiesterase 5 (PDE5) inhibitor, vardenafil, has the potential to be a boon for those with diabetes-induced erectile dysfunction. These drugs are used as disposable treatment drugs, and after oral administration about 1 hour before sexual intercourse, they increase the concentration of cGMP induced by selective inhibition of PDE5 action, nitric oxide (NO) released after blocking stimulation, relax arterial vascular smooth muscle, and enhance erectile function.
