Mechanism of action

Levitra chemical formula
Levitra chemical formula
When a person gets horny, the little signals are forwarded thorough his nervous system. A bunch of chemical messages are released by these signals inside the tissues of male organ. Cyclic GMP is among these chemicals. Its main aim is to calm and soothe a layer of muscles that are in vessel walls of blood inside the penis's tissues. This relaxation and soothing makes the vessels of blood wider, which makes a constant blood flow into the penis. It makes a tough erection.

Actually, when the sexual intercourse is finished successfully, a bigger amount of chemical are forwarded through your body. One of these messenger's name is PDE-5. It can break down cGMP. When it happens, cGMP can not function any longer and the vessels of the blood decrease and become of their actual size. After that, penis becomes the previous form and flabby.

When a man takes vardenafil, PDE-5 stops doing its work and it doesn't break down the cGMP. Once cGMP is not broken down, vessels of blood can not be returned to their usual condition and the intense blood flow goes to the penis. It makes an erection much longer, lasting and stronger.


GlaxoSmithKine, Bayer Pharmaceuticals and Schering-Plough had made a joint marketing to produce vardenafil with a new brand name Levitra. In 2005, in lots of market outside United States, GSK had given back Levitra to Bayer. But in Italy, GSK sells vardenafil with a name Vivanza and Bayer sells it like Levitra. In this manner, to comply with some of trade rules of European Union, parallel imports have to be resulted in Vivanza traded next to Levitra in the EU.

Another form of vivanza that is disintegrated orally is sold with a nameStaxyn. Such countries like Canada and United Stated had already given their approval to it.

We ask you not to purchase generic Levitra, only if you are sure that this is and approved version.

Levitra's first patent is finishing in 2018. So, only after that date it is possible that there will be a generic Levitra. The exclusivity period could be stopped before 2018 under such circumstances like a lawsuit against the drug or some company will get a patent on using Levitra for another disease. The time when Levitra runs out from patent, a great amount of other companies will try to get in charge of manufacturing the generic drug.

Alpha blockers
A decreased blood pressure was observed during the studies that were made previously in the patients that had benign prostatic hyperplasia or high blood pressure when they used Levitra and alpha blockers at the same time. There were cases when people had dizziness, giddiness and fainted when they lied or sat and quickly stood up. Your doctor can adjust your doze of the medicine when you have treatment with alpha blockers.

Specific antifungals or antibiotics
The level of Levitra in your blood increases when you take specific antifungals and antibiotics, bringing more dangerous side effects. When you are using both of these drugs, you should ask the doctor if you should take a lower dose of Levitra. Those patients that use this medicine should limit their dose to 2.5-5 mg of the medicine during the period of 24 hours. But it depends what drugs and you are taking and what is their dose.

Grapefruit juice
We don't know how Levitra interacts with grapefruit juice because no studies have been made with it. It is possible that the level of Levitra will be increased in your blood because of grapefruit juice and therefore the side effects will be more dangerous. That is why we don't really recommend you to take this medicine until there will be more information about it.

Medicine for arrhythmia
Levitra is forbidden for those that use specific drugs for treating not normal rhythms of the heart, like sotalol, procainamide, quinidine, and amiodarone. Patients that take Levitra with one of these drugs can provoke a very perilous type of arrhythmia that is called QT prolongation.

It is not recommended to use this medicine when you get treatment with nitrates. It also concerns those recreational drugs which they name "poppers" that may include butyl nitrate or amyl nitrate. A patient could suffer from hypotension or decreased blood pressure when he combines this medicine and nitrates.

PDE5 Inhibitors
It is better not to take Levitra with other similar drugs, because it is also a PDE5 Inhibitor.

Protease inhibitors
The level of this medicine will be increased together with its side effects if you take protease inhibitors. May be it is better to take a decreased amount of Levitra. Ask for an advice from your doctor if you can take these two drugs together.


Probably we didn't list all of the interactions with this medicine in our article. That is why we recommend to speak with your doctor or a pharmacist about combination of this drug and the one that you are possibly taking at the moment.

My age is 78 and I was taking this medicine for more than four years. If I don’t eat and take a 5mg pill, my erection will be very strong. You need to wait for half an hour to get an effect. I have some redness on my face but it doesn’t really bother me.

I took a dose of 10mg of the medicine with water and didn't take food one hour before sex. I was so impressed by results!

My age is 36 years old. For the last time, it is difficult for me to maintain my erection when I am going to have sex. But I still have it, when I have foreplay. When I got a prescription for Levitra, it changed my life. I felt young and strong. There were some problems with engorgement and I sometimes I had headaches, but it is not compared to result. The negative side is that you have to know when you need to have sexual activity. No spontaneity and no romance. The price for medicine is also high.
