Eli Lilly's tadalafil was the little blue pill's lesser sibling at first, but it's gained momentum, especially outside the U.S. With a low-dose pill approved yesterday by the FDA, is may just pull ahead domestically, too.
Taken daily, the low-dose version allows men to attempt sexual activity anytime. Previously, men had to take tadalafil ahead of time; it remained effective for 36 hours. Other treatments work for about four hours.
Lilly hopes that this new, more convenient dosing helps sales continue to grow: For the first nine months of 2007, the drug brought in $798 million, and the company expects it to top $1 billion for the full year. The nine-months results are 30 percent higher than same-period-last-year sales.
