Web sites for Pfizer’s smoking cessation drug Chantix, erectile dysfunction drugs Cialis, marketed by Lilly and Pfizer’s Viagra were the top three online branded pharma product portals driving offline consumer prescription requests, a new study shows.

The product site rankings were based on an online consumer research study of 5,112 US adults conducted by market research firm Manahattan Research.

“Having the most unique visitors is no longer the ultimate goal of a successful pharmaceutical product site,” said Manhattan Research president Mark Bard in a statement. “Brand teams and agencies are being challenged to demonstrate the economic and strategic value created by these online destinations – beyond the raw number of visitors or page views.”
