Genetic Engineering & Biotechnology News has compiled a list of the top 20 best-selling prescription drugs worldwide for 2012. GEN's list, which the journal released on March 5 (see "Top 20 Best-Selling Drugs of 2012"), was based on sales figures obtained from biopharma company press announcements, annual reports, and conference calls during 2012 and 2011. For each drug on its list, GEN has provided 2011 and 2012 sales, percent change from 2011 to 2012, and Q4 sales and percent change for both 2011 and 2012. 2012 sales for the top 20 drugs range from $3.81 billion to $9.265 billion. GEN's top 20 rankings are shown below, with the additional designation of small molecule or biologic for each drug that made GEN's list.
