Levitra Powder Vardenafil Briefing:
Vardenafil, known under the brand name Levitra is a prescription medication for male erectile dysfunction treatment. It belongs to a class of drugs called PDE5 inhibitors. Levitra increases blood flow to the penis, which helps gain and sustain an erection during sex. Levitra’s active ingredient works on the chain of reactions within the penis during arousal, when the corpus cavernosa (two large chambers) in the male’s penis fills with blood, resulting in an erection.
Vardenafil is best taken 1 hour before sexual activity and should only be taken once per day. Doses need to be taken at least 24 hours apart.

Levitra Powder Vardenafil Application:
Vardenafil is an oral drug that is used to treat impotence, the inability to attain or maintain a penile erection. It has a mechanism of action that is similar to sildenafil (Viagra), and tadalafil (Cialis). Penile erection is caused by the engorgement of the penis with blood. This engorgement occurs when the blood vessels delivering blood to the penis increase in size and increase the delivery of blood to the penis. At the same time, the blood vessels carrying blood away from the penis decrease in size and decrease the removal of blood from the penis. Sexual stimulation that leads to the engorgement and erection causes the production and release of nitric oxide in the penis. Nitric oxide then activates the enzyme, guanylate cyclase to produce cyclic guanosine monophosphate (cGMP). The cGMP is primarily responsible for increasing and decreasing the size of the blood vessels carrying blood to and from the penis, respectively. Vardenafil prevents an enzyme called phosphodiesterase-5 (PDE-5) from destroying cGMP so that cGMP persists longer. The longer cGMP persists, the more prolonged the engorgement of the penis. Vardenafil was approved by the FDA in August 2003.
How vardenafil and tadalafil work?
Like sildenafil, vardenafil and tadalafil are selective inhibitors of the phosphodiesterase (PDE) isoenzyme PDE-5, which is predominantly responsible for degrading cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the corpus cavernosum.During sexual stimulation, nitric oxide is released from cavernous nerves and endothelial cells and activates the enzyme guanylate cyclase, resulting in increased cGMP synthesis. The cGMP triggers relaxation of smooth muscles, allowing increased blood flow into the penis and expansion of sinusoidal spaces; this prevents venous blood outflow and results in erection. The PDE-5 inhibitors can potentiate erections by enhancing and prolonging the smooth musclerelaxant effects of the nitric oxide-cGMP cascade in the corpus cavernosum.1 PDE-5 inhibitors have no effect without sexual stimulation.
Vardenafil For Bodybuilding
Vardenafil is commonly used by bodybuilders and professional athletes as performance enhancing drugs.
Vardenafil can increase blood flow not only to the penis, but to the rest of the body as well. This will cause a much more intense “pump” and also increase the speed of nutrients being shuttled to the muscles.
Another thing Vardenafil do is actually increase testosterone levels.Vardenafil do this by preventing some conversion from testosterone to estrogen.This will actually result in higher testosterone and lower estrogen levels.Bodybuilders must remember that while Vardenafil is very effective as a “pre workout” drug,the body can become dependent on them very quickly.This could potentially lead to someone needing Vardenafil for sexual activity.
