Top 10 Biologic Drugs in the United States

These Drugs Are Changing the Way Illnesses Are Treated

Biologics are drugs made from complex molecules manufactured using living microorganisms, plants, or animal cells. Many biologics are produced using recombinant DNA technology. They are sometimes referred to as biopharmaceuticals or biological drugs.

Biologics have revolutionized the treatment of many serious and chronic illnesses and have nudged traditional small-molecule drugs out of the top sales slots. Rheumatoid arthritis, certain cancers, and diabetes have the greatest numbers of dedicated biologic treatments.

Biologics are changing the ways doctors treat common conditions that have plagued individuals for years.

Generic Biologics

While most drugs are chemicals synthesized from other chemicals, biologics are much more expensive due to their complex manufacturing process. Because of their high cost, there is a great demand for generic versions of biologic medications.

Several pharmaceutical companies are lobbying for the right to manufacture generic versions. However, because they are so difficult to manufacture, there are concerns about the ability to manufacture generics both safely and reliably.

The 10 drugs on the list all have exceeded the monetary definition of a "blockbuster" which designates a drug as having generated more than $1 billion in annual sales. Figures are based on 2018 sales data reported by the respective manufacturers for revenues generated in 2017.
