ED and Levitra

Erectile dysfunction (ED,buy levitra ) — the consistent or recurrent inability of a man to attain and/or maintain a penile erection sufficient for sexual performance(5) — is a common health condition among men that is largely untreated. It is estimated that some degree of ED affects more than one half of all men over the age of 40(6) — 152 million men worldwide(7) and 30 million men in the United States alone.(8) Despite the high prevalence of sexual problems, nine out of 10 men in the U.S. have not yet sought treatment from a physician.

Bayer and GlaxoSmithKline signed a worldwide co-promotion and co-development agreement for Levitra in November 2001. To date, Levitra has received regulatory approval for the treatment of ED in more than 50 countries. It was launched in major European (levitra order) markets beginning on March 7, 2003.

As previously disclosed, Pfizer has filed suit in the United States alleging that one of its patents would be infringed by the sale of Levitra. The case is in its early stages.
