What is Levitra

order cheap levitra

The levitra pills are the medicine that belongs to a group for treatment of erectile dysfunctions with vardenafil as main working ingredient.This active component possesses a selective action towards PDE-5, which plays key role in the physiological mechanism of male erection. Vardenafil suppresses the PDE-5 leads to an increase of the levels of cyclic guanosine monophosphate, relaxation of the unstriated muscular tissue of the blood vessels, and as a result to an increased blood inflow towards penis tissues. According to levitra reviews, its effect can be developed only in presence of sexual stimulation which is required for the release of nitrogen oxide from the nerves ends of cavernous bodies; and this in turn triggers the reaction of rising level of guanosine monophosphate (cyclic form). Thanks to the high level of vardenafil selective action in regard of PDE-5 original and generic levitra does not have impact on organs and systems, which functions are being regulated by other kinds of PDE.

After specified levitra dosage has been taken orally    the peak of plasma concentration of vardenafil can be observed in 45-90 minutes, or in 30-120 minutes. The half-live of levitra main ingredient varies from four to six hours; its excretion is mainly done through intestine and partly by kidneys.

There is some possibility of some alterations of pharmaceutical kinetic profile of vardenafil among elderly patients and patients with reduced kidney and liver functions. However, such alterations are not significant, hence, no need to correct the initially prescribed dosage.

The daily dose of the drug should not be taken more than once a day. Also the initial dose of levitra should not exceed 5 mg for the patients with decreased kidneys and liver functions.

  • Confirmed non-tolerance of vardenafil or any other levitra components;
  • Phenylketonuria;
