As a PED5 Inhibitor, Vardenafil functions by relaxing the muscles and forcing more blood into the penis in order for an erection to be obtained or maintained. ED can be defined by the inability to obtain or maintain an erection or in some cases the inability to obtain or maintain a full and ridged erection.
The ED drug Levitra, like all similar PED5’s, functions by binding nitric oxide to the guanylate cyclase receptors thereby increasing cGMP levels. This creates a smooth relaxation of the muscle and creates a pathway for increased blood flow
While Levitra is very similar to Viagra and Cialis it is more closely related to Viagra with the only difference being the position of a nitrogen atom and the addition of an ethyl group rather than methyl group. The slight alteration gives Levitra a slightly longer active life than Viagra but still much shorter than Cialis.
Levitra is found in a round orange tablet form, medication is available in 2.5mg, 5mg, 10mg and 20mg forms. The drug may be taken with or without food and is to be taken 1-2 hours prior to sexual activity.
Levitra is an excellent ED medication and most users will find it very similar to Viagra. When comparing Levitra to Viagra, in terms of which one to pick, it will almost always boil down to individual preference. You may have to try both at different times to find which one works best for you. The same can be said of Cialis, although because Cialis carries such a long active life, 36-48 hours, it is somewhat in a class of its own.
