The second most popular male erectile dysfunction drug on the market (second only to Viagra of course) called Cialis, is a drug under a company that is being absorbed by the drug giant Eli Lilly.  The deal was recently inked between the more well known Eli Lilly to aquire the smaller biotech firm who created Cialis called ICOS Corp. 

Reportedly Cialis has been Viagra’s toughest competitor since Eli Lilly and ICOS launched it in a joint marketing and manufacturing effort back in 1998, and in some areas it has even beaten the sales of Viagra. 

The company is hoping that its acquisition of the smaller biotech firm will help boost its profitability and investability in 2008 (guess 2007 is too early to expect a return).  Cialis has gained notoriety and sometimes preference over Viagra because it supposedly give a longer lasting erection than Viagra, many times working up to 36 hours (of course hopefully not with a full erection this whole time).

Cialis may exceed sales of 1 billion dollars by the end of 2007.
