Viagra, Pfizer's erectile dysfunction drug, will go before a U.S. review of tests performed in children with a rare form of high blood pressure in the lungs, according to a Bloomberg report.

Pfizer shares are up $0.22, or 1.43%, to $15.24.
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
