What Is a Biologic Drug?
A biologic drug is a medication made from living cells or organisms, or produced using biotechnology. Unlike many traditional medications that are made through chemical processes, biologic drugs are designed to target specific parts of the immune system or disease process.
Biologic drugs are commonly used to treat autoimmune diseases, inflammatory disorders, certain cancers, and other chronic medical conditions.
