Vardenafil – General information
Vardenafil is used to treat erectile dysfunction (impotence), which happens when you can’t get and maintain a penile erection. It does so by relaxing the muscles in the walls of blood vessels in order to increase blood flow to certain areas of your body. Levitra is the brand name of vardenafil and is part of a group of drugs known as phosphodiesterase 5 (PDE5) inhibitors. The other components of this group are sildenafil (Viagra), tadalafil (Cialis), and avanafil (Stendra). They all work to treat erectile dysfunction by blocking an enzyme called phosphodiesterase type 5.
Differences between PDE5 Inhibitors
While these four drugs all have a similar mechanism of action, they have some different characteristics. It’s important to know what differentiates them because it can help you and your doctor choose the medicine that better suits your needs and lifestyle.

How and when to take Vardenafil Levitra
You should take the oral drug only when needed, about 60 minutes before sexual activity. Please note that the medicine will only work when you are sexually aroused. When you are ready to take the medicine, remove the Vardenafil HCl 20mg tab from the package and place it in your mouth. Let it dissolve without chewing. Levitra is a rapidly disintegrating tablet, so there is no need to take it with water.
The drug is available in tablets of 2.5 milligrams (mg), 5 mg, 10 mg, and 20 mg. Doses must be selected and prescribed by your doctor. You can take it with or without food, but drinking alcohol with the medication is not advised. Alcohol can reduce your chance of getting an erection, and using Vardenafil with alcohol can increase the risk of adverse effects.
In most cases, the effect of the drug can last up to 5 hours. You can take a maximum of one tablet, every 24 hours. Seek emergency medical attention if the erection is painful and lasts longer than 4-5 hours.
Common adult doses for erectile dysfunction
It is important that you decide the dosage with your doctor, in order to get the best results. However, the most common doses are:
- Initial dose of vardenafil Levitra: 10 mg once a day, 60 minutes before sexual activity. You may decide to increase the dosage depending on how you react to this initial dose.
- Maximum indicated dose: one tablet of vardenafil 20 mg per day.

Placebo vs. Vardenafil Study
We are now going to present to you the results of a placebo-controlled study with vardenafil. The measurements of penile rigidity and tumescence were made using the monitoring device RigiScan Ambulatory Tumescence Monitor.
The first phases of the study: 80% of patients experienced improved erections
During the first phase of the study, compared with a placebo, the drug significantly increased rigidity and duration of erections in response to visual sexual stimulation. In the second phase, 601 men were randomized to 12 weeks of treatment with placebo or 5, 10 and 20 mg of vardenafil. Results showed that 80% of patients experienced improved erections. In contrast, only 30% of those taking placebo experienced improvements. Improvements were not affected by factors such as age, etiology of the disorder and baseline severity and the effectiveness was maintained throughout the entire study period.
The final results
The third and final phase of the study was conducted across 54 centers in Canada and the United States. Patients included in the study had erectile dysfunction with various degrees of severity and many had comorbid diseases such as depression and heart disease.
All participants were randomized to 26 weeks of fixed-dose treatment with either vardenafil or a placebo. The drug substantially increased erectile function compared with the placebo. During the study, erections were reported by up to 85% of men who took vardenafil 20mg. In contrast, erections were noted by only up to 28% who took the placebo.
In summary, the study results showed that vardenafil improved patients’ ability to penetrate and maintain erections to completion of intercourse. The success rate of penetration doubled from 41% to 80% at week 12 for vardenafil patients, and the ability to maintain an erection for the duration of intercourse increased dramatically from 15% to 65%.
