U.S. prescription sales grew by 8.3%, to $274.9 billion, from 2005 to 2006.
According to IMS Health, measured by dollars, U.S. prescription sales grew by 8.3%, to $274.9 billion, from 2005 to 2006. Measured by number of prescriptions dispensed, the growth rate was 4.6% versus 3.2% in 2005. The market research firm attributes the growth in both dollars and units to several factors, including the implementation of Medicare Part D, increased use of generics in new drug classes, and the availability of new treatments for cancer and diabetes. Looking ahead, IMS predicts that four to seven product launches in 2007 have blockbuster potential and generics will take an even greater toll on brands.
