FDA grants pediatric extension for Viagra and Revatio:

http://online.wsj.com/article/BT-CO-20120217-711435.html

Viagra now has US exclusivity until Apr 2020 and Revatio has US exclusivity until Sep 2012 (oral) and May 2013 (IV).

Viagra has US exclusivity for seven years longer than Revatio because PFE’s “use” patent for sildenafil in treating ED stood up to judicial scrutiny in a case decided last summer. As noted in #msg-66190222, it probably helped PFE’s case considerably that the use of sildenafil for ED was discovered by accident.

“The efficient-market hypothesis may be
the foremost piece of B.S. ever promulgated
in any area of human knowledge!”
