What is a blockbuster drug?
A blockbuster drug is a medication that generates annual sales of $1 billion or more. These drugs usually treat conditions that affect many people -- like hypertension, high cholesterol, cancer, arthritis, and diabetes -- and require chronic care over the long term.
Examples of blockbuster drugs include AbbVie's (ABBV +0.02%) Humira -- an anti-inflammatory drug used to treat a host of conditions, including rheumatoid arthritis and Crohn's disease -- and Pfizer's (PFE -0.02%) cholesterol drug Lipitor.
