Biologic Drug

Definition

A medication derived from living organisms or their components, including proteins, antibodies, vaccines, and gene therapies. Biologics are larger and more complex than traditional small-molecule drugs, require specialized manufacturing, and are typically administered by injection or infusion.

Example

Insulin, monoclonal antibodies like trastuzumab (Herceptin), and mRNA vaccines are all biologic drugs produced using living cell cultures.
