The professional prognosticator EvaluatePharma recently released its World Preview 2019, Outlook to 2024 report, which projects prescription drug sales and R&D activity in the U.S. and abroad. (The report is free with site registration.)
You’ll find predictions for the ten best-selling U.S. drug products on page 24. Below is my handy summary chart comparing the 2024 list along with each product’s 2018 sales. For fun, I have also compared the 2018 actual sales with EvaluatePharma’s projections from 2013.
