Levitra Online from My Canadian PharmacyTable of Contents

What Is Levitra?

Levitra is a medication created to carry out treatment of erectile dysfunction. The active agent of medicine is Vardenafil. What does occur in an organism under its influence? Cavernous bodies and genital vessels relax and freely pass blood. At the same time, the blood-groove in bodies of a small pelvis and in genitals amplifies and actively fills cavernous bodies. At natural sexual excitement (and only in this case) there is a firm erection.

Erection disappearance is connected with the production of the special substance PDE-5. It brings the cavernous body to a sluggish state again, narrows vessels and pushes out blood from a penis. Vardenafil slows down development of PDE-5. Blood for a long time remains in a penis. The erection remains longer, and sexual intercourse becomes longer. Besides, the genitals which are plentifully filled with blood are much more sensitive. Therefore feelings during proximity become brighter and intensive.

Vardenafil is completely brought from an organism within 24 hours. To avoid overdose, the interval between reception of means has to be not less than twenty-four hours.

And, the issue “Levitra Price” with generics is resolved easily. They are several times cheaper than original preparations. Therefore it is much simpler to any human being to buy Levitra now. The price of generics is quite available to their average inhabitant, especially on My Canadian Pharmacy.

Many are guarded by such difference in the price. But the reason is perfect as well as is transparent. Development of a new original preparation demands from the company developer of huge costs for researches, tests, advertising and development of the production technology.

Therefore at the same properties also the price is lower.

During a study in healthy volunteers, Vardenafil was tested in single doses of up to 120 mg per day. One-time doses of vardenafil to 80 mg and multiple doses up to 40 mg of Vardenafil, administered once a day for 4 weeks were tolerated without the occurrence of serious adverse side effects.

However, with Vardenafil application in a dosage of 40 mg 2 times per day, pronounced lower back pain without signs of toxic effects on the muscular and nervous systems was recorded.

In cases of overdose, standard maintenance therapy should be carried out.

Since Vardenafil combines highly with plasma proteins, and only a small amount of the drug is excreted by kidneys, the level of hemodialysis effectiveness is low.Levitra - Read More About Side Effects and Contraindications
