Upraise of Erectile Dysfunction Drugs usage
June 01, 2007

In this world of 21st century everybody have change their mentality. People are now more focused on their issues and are more opened. Now people do not feel shy to discuss about erectile dysfunction and its related issue. Every evening while watching TV, I see at least one ad, and sometimes several ads, for a pill that treats erectile dysfunction, ED. And this is during prime time.

Since these were not available before 10 years ago that's might be the reason that early people are not that much open to such issues. Like Viagra wasn't approved for use by the Food and Drug Administration until March 27, 1998. Cialis came to approved in the year 2003. After the drugs approval by FDA people feels free to discuss such issues.

Viagra, which is also known as Sildenafil citrate, was the first medicine approved to treat Erectile Dysfunction in the United States. It has put on by Pfizer Inc. Viagra is giving good sales with a yield of 4.3%. It has a P/E of 10.5 and its PEG is 2.5. The latest year over year, quarterly salary from continuing operations were up over 245%, however, income were down over 7%.

Another participant in the ED market is the Bayer AG, which produces vardenafil; it is famous with the name of Levitra. This German stock, which trades on the New York Stock Exchange, has giving a PEG of 1.6. and P/E of 27. It pays a small yield of 1.5%.
Cialis (the most important drug), and can be called as tadalafil. It has been created by Eli Lilly And Company in 2003. Most of people called Cialis as weekend pill as its consequence last up to 36 Hours. Lilly has given a PEG of 2.3 and a P/E of 27.

From all the above three drugs cialis is giving the maximum advantage i.e it can works for 36 hours. Due to its extra feature people prefer to take cialis as it avoid the time boundation to enjoy that time.
