What is the difference between Levitra and Viagra?

Viagra and Levitra are drugs that are used for erectile dysfunction. The chemical compound in Viagra takes about half-hour to start its course of action, and the effects last for about four hours. It was the first approved drug for this purpose and was discovered during a drug trial for pulmonary hypertension medication. It is in the class of PDE-5 inhibitors. PDE-5 inhibitors stop the action, which causes degradation of cyclic GMP in smooth muscle cells. Levitra, on the other hand, is not as well- known as a drug for this disorder. It is mainly used to treat ED, and the effects are said to last for a long time. This drug is effective in small doses of 10-20mg. The duration of onset biological action is low. Levitra tends to give a higher duration of six hours.
