Use Of Cheap Levitra

The usage of drugs which improve the erection is a quite delicate question. The most famous representative of this group of drugs is Viagra, but it has several disadvantages. From one side, the drug has a significant list of side effects and it has it`s safer substitutes. On the other hand, the high cost of Viagra is dictated solely by its fame and popularity in popular culture. One can buy Levitra online, which will be not only be more efficient, but also better in terms of price / quality ratio.

Active ingredient of the drug

Levitra is produced by the German company Bayer. It consists of the active ingredient vardenafil, which belongs to the class of phosphodiesterase-5 inhibitors (PDE-5). All drugs from this pharmaceutical group are the remedies to eliminate erectile dysfunction.
This Levitra is available in two forms: ordinary tablets in a protective coating and tablets soluble in the oral cavity (Levitra ODT). The last ones are much more expensive, but lead to a more rapid development of a positive effect.

Mechanism of action

The basis of the development of an erection is the relaxation of the musculature of the cavernous bodies of the penis and the dilatation of the vessels contained in it. These processes lead to the filling of the cavernous bodies with blood, which manifests itself in the form of an erection. During sexual arousal, the cells of the inner lining of the arteries of the penis begin to produce NO. Nitric oxide pulls the formation of guanylate cyclase and an increase in the formation of cGMP in the smoothes muscles of the cavernous bodies. The enzyme phosphodiesterase-5 cleaves cGMP, controlling the degree and duration of erection.
Since cGMP is itself responsible for the relaxation of smoothness of muscle cells, it is most advantageous to cause an increase in its concentration. It is not possible to do this by introducing NO: nitric oxide quickly decomposes, and the resulting cGMP rapidly decomposes under the action of PDE-5. Thus, it is much more effective to affect on the cGMP degrading enzyme.
Vardenafil, which is part of Levitra, blocks the activity of the PDE-5 enzyme. This leads to the accumulation of cGMP, increased relaxation of the smooth muscles of the penis, blood flow and the development of erection.
There are more than 10 types of phosphodiesterase. Its fifth type (PDE-5) participates in the processes of sexual arousal, while others take part in the regulation of vascular tone of other organs and tissues, the regulation of color perception and other processes. The main disadvantage of Viagra is the relatively low selectivity in relation to the suppression of PDE activity. This leads to the main side effects of the drug in the form of a drop in blood pressure, facial flushing, nasal congestion, and visual impairment.
Levitra interacts primarily with PDE-5. It is 15 to 1000 times more active with respect to this form of the enzyme than with other phosphodiesterases.
