This medicine is intended to treat erectile dysfunction in men. This pathology is the lack of erection and inability to conduct intercourse by a man. The active substance of Levitra is vardenafil.
Levitra is available in tablet form. One tablet contains from 5 to 20 mg of the active ingredient vardenafil. The tablet is protected by a blister made of foil. The package contains one blister with tablets.
The drug resolves problems with erectile function and enables a man to hold sexual intercourse. Erection is achieved by filling of the cavernous bodies of the penis by blood. Normally this is possible by relaxing the smooth muscles and active inflow of arterial blood. Active ingredient Levitra blocks the enzyme that reduces the concentration of cGMP in cavernous bodies. This process is possible in the presence of nitric oxide. The whole process was studied in detail by a group of scientists, and they held clinical test series in which experimental animals (rabbits and a control group of rats) and male volunteers participated.
The active ingredient enters the bloodstream by absorption through the stomach mucous. This process takes only 15 minutes. After oral administration the total duration of Levitra action reaches 5-6 hours. The peak activity of the drug occurs within an hour after taking. Fatty food influences the time of activation of therapeutic action. Properties of the active ingredient are not reduced.
In order for a stable erection to occur, a certain kind of enzymes are needed, where the main role is played by cGMP. Under their influence, the genital arterioles relax, which are located in the muscles of the muscles of the cavernous bodies of the penis. This is a healthy mechanism for the male organ to take an erect state. In order to form cGMP, sexual arousal and an essential nitric oxide component are necessary. The drug acts precisely to block the splitting of the cGMP enzyme, which guarantees a long-lasting quality erection.
Vardenafil 20 mg allows you to achieve a long erection. Thanks to the active component, blood flow to the cavernous bodies of the penis is selectively enhanced, which is why a high-quality erection occurs. It is worth noting that the drug is not hormonal and does not affect the psyche. Levitra 20 mg is not intended for arousal, its reception only guarantees a quality erection if there is a strong sexual desire.
Vardenafil is prescribed only after consulting a cardiologist and andrologist, taking into account the peculiarities of the circulatory system and the accompanying illnesses. Despite good tolerability, an individual dosage can be selected only by a qualified specialist. All the risks are taken into account. Not following the rules for taking the drug, taking without indications or exceeding the dose is dangerous due to the development of hypertensive crisis and cardiac conduction failures. Usually, the drug is prescribed in a dose of 15-25 mg. Often, the dosage is started with a lower dose (10 mg) before the onset of clinical effect. A single maximum dosage should not exceed 40 mg per day.
According to the results of the Cologne clinic tests, the drug is much more effective and safer than its analogues. Clinical manifestations of Vardenafil significantly exceed the effect of drugs of the first generation, the action lasts up to five hours. This time period is the optimal balance between prolonged erection and the load on the circulatory system.

Medical experts associate the effectiveness of this drug with the individual characteristics of the body when entering into contact with vardenafil.
