What is Verdanafil
LEVITRA (vardenafil hydrochloride) is administered orally for the treatment of erectile dysfunction. This monohydrochloride salt of vardenafil is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5).
Vardenafil HCl is designated chemically as piperazine, 1-[[3-(1,4-dihydro-5-methyl-4-oxo-7-propylimidazo[5,1-f][1,2,4]triazin-2-yl)-4-ethoxyphenyl]sulfonyl]-4-ethyl-, monohydrochloride
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 approved by FDA in August 2003.

What are the side effects of vardenafil?
The most common side effects are facial flushing (reddening), headaches, stomach upset, diarrhea, flu like symptoms, and nausea. Vardenafil also may cause chest pain, low blood pressure, blurred vision and changes in color vision, abnormal ejaculation and priapism (painful erection lasting more than 6 hours). Patients should seek immediate medical help if they experience an erection lasting more than 4 hours.
What is the dosage?
Recommended dose of vardenafil is 10 mg per day 60 minutes before intercourse. If no response or side effects, increase dose to 20 mg.
Individuals 65 years of age or older should begin therapy with 5 mg.
Orally disintegrating tablets (ODT) are not interchangeable with regular tablets because they are better absorbed and produce higher blood levels than regular tablets. However, the recommended dosing when using ODT is one tablet 60 minutes before intercourse. Place on the tongue until it disintegrates and not swallowed with water.
Which drugs or supplements interact with vardenafil?
The breakdown and elimination of vardenafil from the body is inhibited by erythromycin, clarithromycin (Biaxin), ketoconazole (Nizoral), itraconazole (Sporanox), indinavir (Crixivan), ritonavir (Norvir), atazanavir (Reyataz), grapefruit juice. Therefore, these drugs increase the concentration of vardenafil in the blood and should not be combined with vardenafil. Moreover, vardenafil reduces the concentration of ritonavir and indinavir and may reduce the effect these drugs.
Is vardenafil safe to take if I’m pregnant or breastfeeding?
However, Its not approved for use in women and has not been evaluated in women who are breastfeeding.
