Biotechnology-derived therapeutic protein is a term used to describe a class of medicines that are created through the use of biotechnology techniques. These proteins are designed to mimic the effects of naturally occurring proteins in the body, and are used to treat a wide variety of medical conditions. There are several synonyms for biotechnology-derived therapeutic protein, including biologic, biopharmaceutical, and biosimilar. Biologics are a type of medicine that is produced using living cells, while biopharmaceuticals are medicines that are made using biological processes. Biosimilars are similar to biologics, but are not exact copies, and are designed to produce similar effects in the body.
